  • Cory Andrew hofstad

    Shalom, I am Cory Hofstad and this is my personal web space for my friends, family and clients to follow my latest projects, adventures, news and updates.

    I am here on a mission for the people, by the people, to make the necessary changes to human society required to recognizably advance our civilization to a point in which we can enter the cosmos and freely travel the stars in a productive and peaceful matter.

    Our species has come to a point where we have two primary choices which we are forced to deal with. Either we continue living in the same ways in which we are currently invested in, which are bringing death, starvation and disease to our planet. Or, we decide to step up to the plate and develop new and innovative strategies to halt the destruction and kick start the process of rebuilding what we have lost and start working toward a better future.

    With the cornered markets refusing to allow any form of sustainable technology through which would cut profits, it is now in my opinion to start forcing through new technologies related to energy, medicine, travel, manufacturing and production.

    While some may say that great advancements are being made in technology, they are for the most part advances in entertainment and distractions from the important staples of human survival. In the last 50 years, we have downsized computers into pocket sized devices, yet we are still forced utilize outdated fossil fuels as a means of energy, while highly advanced clean energy patents are bought out and thrown under the rug.

    The current field of medicine is designed to manufacture patients through prescribing drugs that cause more problems than they solve, and dis-guarding natural solutions for those that come with an expensive patent. Fake diseases and symptoms are created to sell pharmaceuticals which create an unnatural brain chemistry and force chemical dependance on the human population.

    Throughout this website, I intend to utilize my presentation skills to promote free thinking and innovative creation in an attempt to reach those who are also invested in the survival and evolution of the human species and spirit. Some of my ideas may be controversial, but they are in fact ideas, thoughts for the reader to ponder on when they are facing the daily issues of economical, ecological, pharmaceutical and mental slavery. I do not intend to offend, I merely intend to spark the thought of "what if things could be different" and to get the wheels turning in a positive direction to actually making things better for the current and future generations.

Typography

Headings

All HTML headings, <h1> through <h6> are available.

h1. Heading 1

h2. Heading 2

h3. Heading 3

h4. Heading 4

h5. Heading 5
h6. Heading 6

Built with Less

The typographic scale is based on two LESS variables in variables.less: @baseFontSize and @baseLineHeight. The first is the base font-size used throughout and the second is the base line-height. We use those variables and some simple math to create the margins, paddings, and line-heights of all our type and more. Customize them and Bootstrap adapts.

Body copy

Bootstrap's global default font-size is 14px, with a line-height of 1.7em. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their line-height (9px by default).

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Nullam id dolor id nibh ultricies vehicula.

<p>...</p>

Lead body copy

Make a paragraph stand out by adding .lead.

Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.

<p class="lead">...</p>

Emphasis

Make use of HTML's default emphasis tags with lightweight styles.

<em>

For emphasizing a snippet of text with stress

The following snippet of text is rendered as italicized text.

<em>rendered as italicized text</em>

<strong>

For emphasizing a snippet of text with important

The following snippet of text is rendered as bold text.

<strong>rendered as bold text</strong>

<small>

For de-emphasizing inline or blocks of text, use the small tag.

This line of text is meant to be treated as fine print.

<p>
  <small>This line of text is meant to be treated as fine print.</small>
</p>

Note: Feel free to use <b> and <i> in HTML5. <b> is meant to highlight words or phrases without conveying additional importance while <i> is mostly for voice, technical terms, etc.

Notice Styles

Use the <p> tag with .success, .warning, .info or .error classes.

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="success">...</p>

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="info">...</p>

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="warning">...</p>

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="error">...</p>

Abbreviations

Stylized implementation of HTML's <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a title attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover.

<abbr>

For expanded text on long hover of an abbreviation, include the title attribute.

An abbreviation of the word attribute is attr.

<abbr title="attribute">attr</abbr>

<abbr class="initialism">

Add .initialism to an abbreviation for a slightly smaller font-size.

HTML is the best thing since sliced bread.

<abbr title="attribute" class="initialism">attr</abbr>

Addresses

Stylized implementation of HTML's element to present contact information for the nearest ancestor or the entire body of work.

<address>

Preserve formatting by ending all lines with <br>.

Blockquotes

For quoting blocks of content from another source within your document.

Default blockquote

Wrap <blockquote> around any HTML as the quote. For straight quotes we recommend a <p>.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

<blockquote>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
</blockquote>

Blockquote options

Style and content changes for simple variations on a standard blockquote.

Naming a source

Add <small> tag for identifying the source. Wrap the name of the source work in <cite>.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
<blockquote>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <small>Someone famous <cite title="Source Title">Source Title</cite></small>
</blockquote>

Alternate displays

Use .pull-right for a floated, right-aligned blockquote.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
<blockquote class="pull-right">
  ...
</blockquote>

</dl>

Note: Horizontal description lists will truncate terms that are too long to fit in the left column fix text-overflow. In narrower viewports, they will change to the default stacked layout.

Horizontal description

Make terms and descriptions in <dl> line up side-by-side.

Description lists

Inline

Wrap inline snippets of code with <code>.

For example, <section> should be wrapped as inline.
For example, <code><section></code> should be wrapped as inline.

Note: Be sure to keep code within <pre> tags as close to the left as possible; it will render all tabs.

You may optionally add the .pre-scrollable class which will set a max-height of 350px and provide a y-axis scrollbar.

Basic block

Use <pre> for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.

<p>Sample text here...</p>
<pre>
  &lt;p&gt;Sample text here...&lt;/p&gt;
</pre>

Prettify

To add colored syntax highlight to the <pre> tag, then use the .prettyprint class or the .prettyprint linenums class.

<?php /** Begin Debug **/ if ($gantry->countModules('debug')) : ?>
    <div id="rt-debug">
    <div class="rt-container">
      <?php echo $gantry->displayModules('debug','standard','standard'); ?>
      <div class="clear"></div>
    </div>
  </div>
  <?php /** End Debug **/ endif; ?>
<pre class="prettyprint linenums"><?php /** Begin Debug **/ if ($gantry->countModules('debug')) : ?>
  <div id="rt-debug">
    <div class="rt-container">
      <?php echo $gantry->displayModules('debug','standard','standard'); ?>
      <div class="clear"></div>
    </div>
  </div>
  <?php /** End Debug **/ endif; ?></pre>

    </tr>
  </tbody>
</table>

Default styles

Individual form controls receive styling, but without any required base class on the <form> or large changes in markup. Results in stacked, left-aligned labels on top of form controls.

Legend Example block-level help text here.
<form>
  <legend>Legend</legend>
  <label>Label name</label>
  <input type="text" placeholder="Type something…">
  <span class="help-block">Example block-level help text here.</span>
  <label class="checkbox">
    <input type="checkbox"> Check me out
  </label>
  <button type="submit" class="btn">Submit</button>
</form>

Optional layouts

Included with Bootstrap are three optional form layouts for common use cases.

Search form

Add .form-search to the form and .search-query to the <input> for an extra-rounded text input.

<form class="form-search">
  <input type="text" class="input-medium search-query">
  <button type="submit" class="btn">Search</button>
</form>

Inline form

Add .form-inline for left-aligned labels and inline-block controls for a compact layout.

<form class="form-inline">
  <input type="text" class="input-small" placeholder="Email">
  <input type="password" class="input-small" placeholder="Password">
  <label class="checkbox">
    <input type="checkbox"> Remember me
  </label>
  <button type="submit" class="btn">Sign in</button>
</form>

Horizontal form

Right align labels and float them to the left to make them appear on the same line as controls. Requires the most markup changes from a default form:

  • Add .form-horizontal to the form
  • Wrap labels and controls in .control-group
  • Add .control-label to the label
  • Wrap any associated controls in .controls for proper alignment
Legend
<form class="form-horizontal">
  <div class="control-group">
    <label class="control-label" for="inputEmail">Email</label>
    <div class="controls">
      <input type="text" id="inputEmail" placeholder="Email">
    </div>
  </div>
  <div class="control-group">
    <label class="control-label" for="inputPassword">Password</label>
    <div class="controls">
      <input type="password" id="inputPassword" placeholder="Password">
    </div>
  </div>
  <div class="control-group">
    <div class="controls">
      <label class="checkbox">
        <input type="checkbox"> Remember me
      </label>
      <button type="submit" class="btn">Sign in</button>
    </div>
  </div>
</form>

Supported form controls

Examples of standard form controls supported in an example form layout.

Inputs

Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.

Requires the use of a specified type at all times.

<input type="text" placeholder="Text input">

Textarea

Form control which supports multiple lines of text. Change row attribute as necessary.

<textarea rows="3"></textarea>

Checkboxes and radios

Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.

Default (stacked)


<label class="checkbox">
  <input type="checkbox" value="">
  Option one is this and that—be sure to include why it's great
</label>

<label class="radio">
  <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
  Option one is this and that—be sure to include why it's great
</label>
<label class="radio">
  <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
  Option two can be something else and selecting it will deselect option one
</label>

Inline checkboxes

Add the .inline class to a series of checkboxes or radios for controls appear on the same line.

<label class="checkbox inline">
  <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="checkbox inline">
  <input type="checkbox" id="inlineCheckbox2" value="option2"> 2
</label>
<label class="checkbox inline">
  <input type="checkbox" id="inlineCheckbox3" value="option3"> 3
</label>

Selects

Use the default option or specify a multiple="multiple" to show multiple options at once.


<select>
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

<select multiple="multiple">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

Extending form controls

Adding on top of existing browser controls, Bootstrap includes other useful form components.

Prepended and appended inputs

Add text or buttons before or after any text-based input. Do note that select elements are not supported here.

Default options

Wrap an .add-on and an input with one of two classes to prepend or append text to an input.

@

.00
<div class="input-prepend">
  <span class="add-on">@</span><input class="span2" id="prependedInput" size="16" type="text" placeholder="Username">
</div>
<div class="input-append">
  <input class="span2" id="appendedInput" size="16" type="text"><span class="add-on">.00</span>
</div>

Search form

<form class="form-search">
  <div class="input-append">
    <input type="text" class="span2 search-query">
    <button type="submit" class="btn">Search</button>
  </div>
  <div class="input-prepend">
    <button type="submit" class="btn">Search</button>
    <input type="text" class="span2 search-query">
  </div>
</form>

Combined

Use both classes and two instances of .add-on to prepend and append an input.

$ .00
<div class="input-prepend input-append">
  <span class="add-on">$</span><input class="span2" id="appendedPrependedInput" size="16" type="text"><span class="add-on">.00</span>
</div>

Buttons instead of text

Instead of a <span> with text, use a .btn to attach a button (or two) to an input.


<div class="input-append">
  <input class="span2" id="appendedInputButton" size="16" type="text"><button class="btn" type="button">Go!</button>
</div>

<div class="input-append">
  <input class="span2" id="appendedInputButtons" size="16" type="text"><button class="btn" type="button">Search</button><button class="btn" type="button">Options</button>
</div>

Form actions

End a form with a group of actions (buttons). When placed within a .form-horizontal, the buttons will automatically indent to line up with the form controls.

<div class="form-actions">
  <button type="submit" class="btn btn-primary">Save changes</button>
  <button type="button" class="btn">Cancel</button>
</div>

Help text

Inline and block level support for help text that appears around form controls.

Inline help

Inline help text
<input type="text"><span class="help-inline">Inline help text</span>

Block help

A longer block of help text that breaks onto a new line and may extend beyond one line.
<input type="text"><span class="help-block">A longer block of help text that breaks onto a new line and may extend beyond one line.</span>

Control sizing

Use relative sizing classes like .input-large or match your inputs to the grid column sizes using .span* classes.

Relative sizing






<input class="input-mini" type="text" placeholder=".input-mini">
<input class="input-small" type="text" placeholder=".input-small">
<input class="input-medium" type="text" placeholder=".input-medium">
<input class="input-large" type="text" placeholder=".input-large">
<input class="input-xlarge" type="text" placeholder=".input-xlarge">
<input class="input-xxlarge" type="text" placeholder=".input-xxlarge">

Note: In future versions, we'll be altering the use of these relative input classes to match our button sizes. For example, .input-large will increase the padding and font-size of an input.

Uneditable inputs

Present data in a form that's not editable without using actual form markup.

Some value here
<span class="input-xlarge uneditable-input">Some value here</span>

Form control states

Provide feedback to users or visitors with basic feedback states on form controls and labels.

Input focus

We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.

<input class="input-xlarge" id="focusedInput" type="text" value="This is focused...">

Disabled inputs

Add the disabled attribute on an input to prevent user input and trigger a slightly different look.

<input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>

Validation states

Bootstrap includes validation styles for error, warning, and success messages. To use, add the appropriate class to the surrounding .control-group.

Something may have gone wrong
Please correct the error
Username is taken
Woohoo!
<div class="control-group warning">
  <label class="control-label" for="inputWarning">Input with warning</label>
  <div class="controls">
    <input type="text" id="inputWarning">
    <span class="help-inline">Something may have gone wrong</span>
  </div>
</div>
<div class="control-group error">
  <label class="control-label" for="inputError">Input with error</label>
  <div class="controls">
    <input type="text" id="inputError">
    <span class="help-inline">Please correct the error</span>
  </div>
</div>
<div class="control-group info">
  <label class="control-label" for="inputError">Input with info</label>
  <div class="controls">
    <input type="text" id="inputError">
    <span class="help-inline">Username is taken</span>
  </div>
</div>
<div class="control-group success">
  <label class="control-label" for="inputSuccess">Input with success</label>
  <div class="controls">
    <input type="text" id="inputSuccess">
    <span class="help-inline">Woohoo!</span>
  </div>
</div>

Default buttons

Button styles can be applied to anything with the .btn class applied. However, typically you'll want to apply these to only <a> and <button> elements for the best rendering.

Button class="" Description
btn Standard gray button with gradient
btn btn-primary Provides extra visual weight and identifies the primary action in a set of buttons
btn btn-info Used as an alternative to the default styles
btn btn-success Indicates a successful or positive action
btn btn-warning Indicates caution should be taken with this action
btn btn-danger Indicates a dangerous or potentially negative action
btn btn-inverse Alternate dark gray button, not tied to a semantic action or use
btn btn-link Deemphasize a button by making it look like a link while maintaining button behavior

Cross browser compatibility

IE9 doesn't crop background gradients on rounded corners, so we remove it. Related, IE9 jankifies disabled button elements, rendering text gray with a nasty text-shadow that we cannot fix.

Button sizes

Fancy larger or smaller buttons? Add .btn-large, .btn-small, or .btn-mini for additional sizes.

<p>
  <button class="btn btn-large btn-primary" type="button">Large button</button>
  <button class="btn btn-large" type="button">Large button</button>
</p>
<p>
  <button class="btn btn-primary" type="button">Default button</button>
  <button class="btn" type="button">Default button</button>
</p>
<p>
  <button class="btn btn-small btn-primary" type="button">Small button</button>
  <button class="btn btn-small" type="button">Small button</button>
</p>
<p>
  <button class="btn btn-mini btn-primary" type="button">Mini button</button>
  <button class="btn btn-mini" type="button">Mini button</button>
</p>

Create block level buttons—those that span the full width of a parent— by adding .btn-block.

<button class="btn btn-large btn-block btn-primary" type="button">Block level button</button>
<button class="btn btn-large btn-block" type="button">Block level button</button>

Disabled state

Make buttons look unclickable by fading them back 50%.

Anchor element

Add the .disabled class to <a> buttons.

Primary link Link

<a href="#" class="btn btn-large btn-primary disabled">Primary link</a>
<a href="#" class="btn btn-large disabled">Link</a>

Note: We use .disabled as a utility class here, similar to the common .active class, so no prefix is required.

Button element

Add the disabled attribute to <button> buttons.

<button type="button" class="btn btn-large btn-primary disabled" disabled="disabled">Primary button</button>
<button type="button" class="btn btn-large" disabled>Button</button>

One class, multiple tags

Use the .btn class on an <a>, <button>, or <input> element.

Link
<a class="btn" href="">Link</a>
<button class="btn" type="submit">Button</button>
<input class="btn" type="button" value="Input">
<input class="btn" type="submit" value="Submit">

As a best practice, try to match the element for your context to ensure matching cross-browser rendering. If you have an input, use an <input type="submit"> for your button.
