Define the height of elements depending on the viewport or match the heights of different elements.

Height

Define the height of elements depending on the viewport or match the heights of different elements.

UIkit’s Height component offers three options to set heights: using simple fixed height utility classes, depending on the viewport or by matching the heights of different elements.

Usage

UIkit provides a number of useful classes to alter an element’s height.

ClassDescription
.uk-height-1-1This class applies a height of 100%. This only works if the parent element has a set height.
.uk-height-small
.uk-height-max-small 		These classes apply a height or max-height of 150px.
.uk-height-medium
.uk-height-max-medium 		These classes apply a height or max-height of 300px.
.uk-height-large
.uk-height-max-large 		These classes apply a height or max-height of 450px.
<div class="uk-height-small"></div>

Viewport height

Add the uk-height-viewport attribute to create a container that fills the height of the entire viewport. You can change the height behavior by adding the offset-top, offset-bottom or expand option to the attribute. Learn more

OptionValueDefaultDescription
offset-topBooleanfalseSubtracts the element’s top offset from its height.
offset-bottomBoolean, Number, Pixel, CSS SelectorfalseSubtracts the height (true) of the sibling that immediately follows the element, the given percentage (Number), Pixel (px) value from element’s own height or the given element’s height.
expandBooleanfalseExpands the element’s height to make a short page fill the viewport.
min-heightNumber0Sets a minimum height. Useful if all children are positioned absolute.
<div uk-height-viewport></div>

<div uk-height-viewport="offset-top: true"></div>

<div uk-height-viewport="offset-bottom: 20"></div>

<div uk-height-viewport="expand: true"></div>

<div uk-height-viewport="min-height: 300"></div>

You can view examples in the tests for Height Viewport and Height Expand.

Match height

To expand all children of a container to the same height regardless of their content, for example inside a grid, add the uk-height-match attribute. You can change the height matching behavior by setting the target or row option to the attribute. Learn more

OptionValueDefaultDescription
targetString> *Elements that should match.
rowBooleantrueBy default only items in the same row will be matched. For example, once 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.
<div uk-height-match>
    <div></div>
    <div></div>
</div>

target is the Primary option, and its key may be omitted if it’s the only option in the attribute value.

<span uk-height-match=".my-class"></span>

Match cards

You can also target and match specific elements inside the container, like cards. Just add the target: SELECTOR option to the attribute.

<div uk-grid uk-height-match="target: SELECTOR">…</div>

Match all

If your grid wraps into multiple rows, only grid columns within the same row are matched. To match grid columns across all rows, just add the row: false option to the attribute.

<div uk-grid uk-height-match="row: false">…</div>

Component options

The table below lists the available settings of the uk-height-match attribute. Learn more

OptionValueDefaultDescription
