Utility

The utility module contains all the utilities and helper classes that you might want when designing a website or application. They solve common design problems efficiently and provide you with generic rules you can easily apply everywhere.

All examples showcased refer to the mini-default flavor, some class names and styles might differ based on the flavor you're using.

Utility

Quick overview

Every website or app has different needs and no UI toolkit can predict them all. The utility module addresses this issue by providing you with a handful of utility and helper classes to make common, repetitive declarations easier. These classes include, but are not limited to, generic border styling and shadows, floats, centering and clearfix classes, some responsive sizing and spacing utilities and a few other things, like a close icon, breadcrumbs styling and visiblity helpers for screen readers.

Quick start

To use the utility module, simply include the link to the flavor you are using and start writing your HTML page as usual. One suggestion we will make is to add the following line inside your HTML page's <head> to utilize the viewport meta tag:

<meta name="viewport" content="width=device-width, initial-scale=1">

Visibility helpers

You can hide content for all your users, using the default hidden attribute. However, we provide you with the .hidden class for the same purpose, as well as the .visually-hidden class which will make your content hidden, except for screen readers.

Sample code

<span class="hidden">Hidden text</span>
<span class="visually-hidden">Screen-reader-only text</span>

Notes

Both classes utilize !important declarations, so be careful when and how to use them.

<span class="hidden visually-hidden">Not a good idea</span>

Don't: Avoid using both classes at the same time. Instead, use .hidden to hide content for all users, .visually-hidden to hide it for non-screen-reader users or aria-hidden="true" to hide it for screen-reader-only users.

Generic borders & shadows

This is a paragraph with a piece of bordered text.

No shadow Small shadow Medium shadow Large shadow

Use the .bordered class to apply a generic black border with 25% opacity to any element. Apart from that you can use the .rounded and .circular classes to create generic border radiuses. Finally, you can use the .shadow-small, .shadow-medium and .shadow-large to add a generic box-shadow to any element, as well as the .shadow-none class to remove it entirely.

Sample code

<span class="bordered">Bordered</span>
<span class="rounded">Rounded</span>
<span class="circular">Circular</span>
<span class="shadow-none">No shadow</span>
<span class="shadow-small">Small shadow</span>
<span class="shadow-medium">Medium shadow</span>
<span class="shadow-large">Large shadow</span>

Notes

All of these classes utilize !important declarations, so be careful when and how to use them.
The .bordered class was originally created with elements such as buttons in mind, to allow users highlighting certain elements in their designs, without having to change any default styles.
All of the above classes can be used with most modern HTML elements.

<span class="bordered rounded shadow-small">Stylized element</span>

Do: You can combine a generic border with any border radius or shadow or even both.

<span class="rounded circular">Bad radius</span>
<!-- or -->
<span class="shadow-small shadow-large">Bad shadow</span>

Don't: Avoid combining two classes of the same type (i.e. two radii or two shadow styles), as they might overwrite each other and cause unexpected behavior.

Responsive sizing & spacing classes

Helper classes for the padding and margin attributes are provided in the form of .responsive-margin and .responsive-padding classes. Both of these classes are responsive, allowing you to collapse the spacing and size of elements on different displays to make better use of the device's viewport.

Sample code

<div class="responsive-padding">Responsive padding</div>
<div class="responsive-margin">Responsive margin</div>

Notes

If the default values of these classes are not suited to your needs, check out the customization page.
Both classes utilize !important declarations, so be careful when and how to use them.

<div class="responsive-padding responsive-margin">Responsive padding and margin</div>

Do: You can use both of these classes to make certain element adapt to changes. This could be especially useful for certain grid layouts.

Breadcrumbs

Root
Folder
File

Breadcrumbs are usually used to show the navigational hierarchy of pages or folders. To use them, simply create a <ul> element that implements the .breadcrumbs class. Inside this unordered list, add as many <li> elements as needed to show your hierarchy. You can add links to the list elements, as necessary.

Sample code

<ul class="breadcrumbs">
  <li><a href="#">Root</a></li>
  <li><a href="#">Folder</a></li>
  <li>File</li>
</ul>

Notes

The separators between breadcrumbs are added using some tricky CSS rules. Due to that, there might be a few browser versions or devices where you can see part of the seams between the element separators.
Breadcrumbs show a hierarchy, an ordered list. However, we do not use the <ol> element, as it might conflict with some custom styles we've seen people use.

<ol class="breadcrumbs">
  <li><a href="#">Does</a></li>
  <li><a href="#">Not</a></li>
  <li>Work</li>
</ol>

Don't: The structure of the breadcrumb component prohibits the use of <ol> in place of the <ul> element.

<ul class="breadcrumbs">
  <li><a href="#">Root</a>
    <ul class="breadcrumbs">
      <li><a href="#">Folder</a></li>
    </ul>
  </li>
  <li>File</li>
</ul>

Don't: Avoid nesting lists, breadcrumbs or a combination of the two inside the .breadcrumbs list, as this might cause unexpected behavior.

Close icon

To create a close icon, simply add an element implementing the .close class.

Sample code

<span class="close"></span>

Notes

The close icon behaves similar to a button when hovering over it or otherwise focusing or selecting it.

<div class="close"></div>

Do: You can use a handful of other HTML elements instead of the <span> element showcased in the example above, most commonly <div> elements.

<button class="close"></button>

Do: If you want your close icon to behave like a button (i.e. register as a button on screen readers and have the required logic attached to it), you can apply the .close class to a <button> element instead. You can even apply any of the button color variant classes.
