Headings

Use the <h1> to <h6> elements to define your headings.

Example

h1 Heading 1

h2 Heading 2

h3 Heading 3

h4 Heading 4

h5 Heading 5

h6 Heading 6

You can add the .uk-h1, .uk-h2, .uk-h3, .uk-h4, .uk-h5 or .uk-h6 class to alter the size of your headings, for example have a h1 look like a h3.

Paragraphs

The global font-size, line-height and regular margins between elements are set through variables, which can be customized. Paragraphs and other block elements stick to these values.

Text-level semantics

The following list gives you a short overview of the most commonly used text-level semantics and how to utilize them.

Horizontal rule

Create a horizontal rule by using the <hr> element.

Example

Blockquotes

For quoting multiple lines of content from another source within your document, use the <blockquote> element.

Example

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam.

Markup

<blockquote>
    <p>Quotation</p>
    <small>Source</small>
</blockquote>

Code blocks

For multiple lines of code, use the <pre> element which defines preformatted text. It creates a new text block that preserves spaces, tabs and line breaks. Nest a <code> element inside to define the code block.

IMPORTANT Be sure to escape any angle brackets in the code for proper rendering.

Example

<pre>
    <code>...</code>
</pre>

NOTE Optionally, you can add the .uk-scrollable-text class from the Utility component, which will set a max-height of 300px and provide a y-axis scrollbar.

Lists

Create an unordered list using the <ul> element and the <ol> element for ordered lists. The <li> element defines the list item.

Example

Markup

<ul>
    <li>...</li>
    <li>...
        <ul>
            <li>...</li>
        </ul>
    </li>
</ul>

<ol>
    <li>...</li>
    <li>...
        <ol>
            <li>...</li>
        </ol>
    </li>
</ol>

Description lists

Create a description list using the <dl> element. Use <dt> to define the term and <dd> for the description.

Example

Description lists

A description list defines terms and their corresponding descriptions.

This is a term

This is a description.

This is a term

This is a description.

Markup

<dl>
    <dt>...</dt>
    <dd>...</dd>
</dl>

Responsive images

All images in UIkit are responsive by default. If the layout is narrowed, images adjust their size and keep their proportions.

Example

Resize the browser window to see the responsive behavior of the image.

NOTE To avoid the responsive behavior and preserve the original image dimensions, add the .uk-img-preserve class to one of your single images. If you have more than one image, you can also add the class to the parent container. This is not required for Google Maps.

Grid

The grid system of UIkit follows the mobile-first approach and accomodates up to 10 grid columns. It uses units with predefined classes inside each grid, which define the column width. It is also possible to combine the grid with classes from the Flex component, although it works only in modern browsers.

Usage

To create the grid container, add the .uk-grid class to a parent element. Add one of the .uk-width-* classes to child elements to determine, how the units shall be sized. The grid supports 1, 2, 3, 4, 5, 6 and 10 unit divisions. This table gives you an overview of the uk-width-* classes that can be applied to units.

We built an intentional redundancy into each set of unit classes, so that for instance the .uk-width-5-10 class will work just as well as .uk-width-1-2.

Example

Take a closer look at the following grid example, which gives you a great overwiew of all basic .uk-width-* classes.

NOTE The grid has no style related CSS. In our example we used panels from the Panel component.

Markup

Here is a simple code example of how the default grid with 2 columns would look like:

<div class="uk-grid">
    <div class="uk-width-1-2">...</div>
    <div class="uk-width-1-2">...</div>
</div>

Responsive width

UIkit provides a number of very useful responsive widths classes. Basically they work just like the usual width classes, except they are prefixed, so that they only come to effect at certain breakpoints. These classes can be combined with the visibility classes from the Utility component. This is great to adjust your layout and content for different device sizes.

IMPORTANT To create a margin between stacking grid columns, just add the data-uk-grid-margin attribute.

Example

Grid gutter

Grids automatically create a horizontal gutter between columns and a vertical one between two succeeding grids. By default, the grid gutter is wider on large screens.

Example

Large gutter

To apply a large gutter between grid columns, just add the .uk-grid-large class.

Example

Medium gutter

To apply a medium sized gutter between grid columns, just add the .uk-grid-medium class.

Example

Small gutter

To apply a smaller gutter between grid columns, just add the .uk-grid-small class.

Example

Collapse gutter

To remove the gutter entirely, just add the .uk-grid-collapse class.

Example

Nested grid

You can easily extend your grid layout with nested grids.

Example

Markup

<div class="uk-grid">
    <div class="uk-width-1-2">...</div>
    <div class="uk-width-1-2">
        <div class="uk-grid">
            <div class="uk-width-1-2">...</div>
            <div class="uk-width-1-2">...</div>
        </div>
    </div>
</div>

Center grid

Add the .uk-container-center class from the Utility component to center a grid column.

Example

Grid divider

Add the .uk-grid-divider class to separate grid columns with lines. To separate grids with a horizontal line, just add the class to a <hr> or <div> element.

Example

Markup

<div class="uk-grid uk-grid-divider">...</div>
<hr class="uk-grid-divider">
<div class="uk-grid uk-grid-divider">...</div>

NOTE The horizontal divider can not be applied to grids with any of the uk-push-* or uk-pull-* classes.

Source ordering

You can change the display order of the columns to keep a specific column order in the source code. Add one of the .uk-push-* classes to move the column to the right and add one of the .uk-pull-* classes to move a column to the left. This allows you for example to flip the columns' display order for wider viewports. The classes can also be used to offset columns, creating additional space between them.

Source ordering is useful for SEO and responsive design, because in narrow viewports the grid will be displayed according to the source order of the markup.

NOTE This feature only works in combination with one of the .uk-width-medium-* classes.

Example

Markup

<div class="uk-grid">
    <div class="uk-width-medium-1-2 uk-push-1-2">...</div>
    <div class="uk-width-medium-1-2 uk-pull-1-2">...</div>
</div>

Match column heights

The Grid component uses Flexbox, so the height of grid columns is matched automatically. To achieve the same effect in older browsers that don't support Flexbox, just add the data-uk-grid-match attribute to your grid. If your grid wraps into multiple rows, only grid columns within the same row are matched. To match grid columns accross all rows just use data-uk-grid-match="{row: false}".

Example

Markup

<div class="uk-grid" data-uk-grid-match>...</div>

NOTE If grid columns extend to a width of 100%, their heights will no longer be matched. This makes sense, for example, if they stack vertically in narrower viewports.

Match height of panels

If you want to match the heights of panels in a grid, just add the .uk-grid-match class. When using the data attribute, you need to add the {target:'.uk-panel'} selector.

Example

Markup

<div class="uk-grid uk-grid-match" data-uk-grid-match="{target:'.uk-panel'}">
    <div class="uk-width-medium-1-3">
        <div class="uk-panel">...</div>
    </div>
</div>

Wrap multiple rows

You can also create a grid with as many columns as you want, which automatically break into the next line. Just add the data-uk-grid-margin attribute to create a margin between the grid rows. Typically this layout is built using a <ul> element.

Example

• Box
• Box
• Box
• Box
• Box
• Box

NOTE You can also apply a custom width to your grid columns. Just add the .uk-width class and use an inline style to define the width. This example uses fixed pixel values for the widths as you would do with images.

• Box
• Box
• Box
• Box
• Box
• Box
• Box
• Box

Markup

<ul class="uk-grid" data-uk-grid-margin>

    <!-- These elements have a width in percent -->
    <li class="uk-width-medium-1-5">...</li>
    <li class="uk-width-medium-3-10">...</li>

    <!-- These elements have a width in pixel -->
    <li class="uk-width" style="width: 100px;">...</li>
    <li class="uk-width" style="width: 150px;">...</li>

</ul>

Even grid columns

To create a grid whose child elements' widths are evenly split, you don't have to apply the same class to each list item within the grid. Just add one of the .uk-grid-width-* classes to the grid itself.

Example

• Box
• Box
• Box
• Box
• Box

Markup

<ul class="uk-grid uk-grid-width-1-5">
    <li>...</li>
    <li>...</li>
</ul>

Responsive width

UIkit also provides responsive grid width classes. You can apply these to maintain evenly sized grid columns, regardless of the device width.

Example

• Box
• Box
• Box
• Box
• Box

Markup

<ul class="uk-grid uk-grid-width-1-2 uk-grid-width-medium-1-3 uk-grid-width-large-1-5">
    <li>...</li>
    <li>...</li>
</ul>

Buttons

To apply this component, add the .uk-button class to an <a> or <button> element. Now you have created a button. Add the disabled attribute to a <button> element to disable the button.

Example

Link Button Disabled

Markup

<a class="uk-button" href="">...</a>
<button class="uk-button" type="button">...</button>
<button class="uk-button" type="button" disabled>...</button>

NOTE If you are displaying a number of buttons in a row, you can add a top margin to them, when they stack on smaller viewports. Just add the data-uk-margin attribute from the Utility component to their parent element.

Color modifiers

There are several color modifiers available. Just add one of the following classes to apply a different look.

Size modifiers

Add the .uk-button-mini, .uk-button-small or .uk-button-large class to a button to make it smaller or larger.

Mini button Mini button

Small button Small button

Default button Default button

Large button Large button

Full width button

Add the .uk-width-1-1 class from the Grid component and the button will take up full width.

Example

Button Button

Markup

<button class="uk-button uk-width-1-1 uk-margin-small-bottom">...</button>
<button class="uk-button uk-width-1-1">...</button>

Button group

To create a button group, add the .uk-button-group class to a <div> element around the buttons. That's it! No further markup needed.

Example

Markup

<div class="uk-button-group">
    <a class="uk-button" href="">...</a>
    <button class="uk-button">...</button>
    <button class="uk-button">...</button>
</div>

JavaScript

You can toggle button states via JavaScript. Just add the data attibute data-uk-button.

Example

Button

Markup

<button class="uk-button uk-button-primary" type="button" data-uk-button>Button</button>

Checkbox buttons

Toggle between a group of buttons like a checkbox by wrapping a <div> element with the data attribute data-uk-button-checkbox around them. This can also be applied to a button group.

Example

Markup

<div data-uk-button-checkbox>
    <button class="uk-button">...</button>
    <button class="uk-button">...</button>
    <button class="uk-button">...</button>
</div>

Radio buttons

Toggle between a group of buttons, like radio buttons, by wrapping a div element that uses data-uk-button-radio around them. This can also be applied to a button group.

Example

Markup

<div data-uk-button-radio>
    <button class="uk-button">...</button>
    <button class="uk-button">...</button>
    <button class="uk-button">...</button>
</div>

Button with dropdowns

A button can be used to trigger a dropdown menu from the Dropdown component. Just add the .uk-button-dropdown class and the data-uk-dropdown attribute to a <div> element that contains the button and the dropdown itself.

Example

Markup

<!-- This is the container enabling the JavaScript -->
<div class="uk-button-dropdown" data-uk-dropdown>

    <!-- This is the button toggling the dropdown -->
    <button class="uk-button">...</button>

    <!-- This is the dropdown -->
    <div class="uk-dropdown uk-dropdown-small">
        <ul class="uk-nav uk-nav-dropdown">
            <li><a href="">...</a></li>
            <li><a href="">...</a></li>
        </ul>
    </div>

</div>

Button group with dropdowns

Use button groups to split buttons into a standard action on the left and a dropdown toggle on the right. Just wrap a <div> element around the button and the dropdown and add the data-uk-dropdown="{mode:'click'}" attribute. Of course, a dropdown can also be applied to a button within a button group.

Example

Markup

<div class="uk-button-group">

    <!-- This is a button -->
    <button class="uk-button">...</button>

    <!-- This is the container enabling the JavaScript -->
    <div data-uk-dropdown="{mode:'click'}">

        <!-- This is the button toggling the dropdown -->
        <a href="" class="uk-button">...</a>

        <!-- This is the dropdown -->
        <div class="uk-dropdown uk-dropdown-small">
            <ul class="uk-nav uk-nav-dropdown">
                <li><a href="">...</a></li>
                <li><a href="">...</a></li>
            </ul>
        </div>

    </div>
</div>
