Sticky

Ready Added in 2.0.0

Make elements remain at the top of the viewport, like a sticky navigation.

Usage

To create an element that remains at the top of the viewport when scrolling down the site, add the gls-sticky attribute to that element.

<div gls-sticky></div>
  • Stick to the top
  • <div class="gls-background-muted gls-height-large">
    <div class="gls-card gls-card-outline gls-card-body gls-text-center gls-position-z-index" gls-sticky="end: !.gls-height-large; offset: 80">Stick to the top</div>
</div>

Note Example elements on this page are only sticky until you scroll down to the next heading and disappear afterwards. This was done so as not to clutter your screen with all variations of sticky containers.

Position

By default, the element sticks to the top of the viewport. You can set the position: bottom option to stick it to the bottom of the viewport.

<div gls-sticky="position: bottom"></div>
  • Stick to the bottom
  • <div class="gls-background-muted gls-height-large">
    <div class="gls-card gls-card-outline gls-card-body gls-text-center gls-position-z-index" gls-sticky="position: bottom; end: !.gls-height-large">Stick to the bottom</div>
</div>

Start

To apply an offset to when the element should start being sticky, add the start option. The value can be in vh, % and px. It supports basic mathematics operands + and -. The default value of 0 means that the element’s top border and viewport’s top border intersect. A CSS Selector will set start to the selected element’s bottom border and the element’s top border.

<!-- Sticks after 200px scrolling -->
<div gls-sticky="start: 200"></div>

<!-- Sticks after scrolling the elements height -->
<div gls-sticky="start: 100%"></div>

<!-- Sticks after 20vh scrolling -->
<div gls-sticky="start: 20vh"></div>

<!-- Sticks after the top of the selected element -->
<div id="my-id">
    <div gls-sticky="start: #my-id"></div>

        </div>
        <div>
            <div class="gls-card gls-card-outline gls-card-body gls-text-center gls-position-z-index" gls-sticky="start: 100%; end: !.gls-height-large; offset: 80">100%</div>

        </div>
    </div>

</div>
<div style="height: 200px"></div>

End

To apply an offset to when the element should stop being sticky, add the stop option. The value can be in vh, % and px. It supports basic mathematics operands + and -. A value of 0 means that the element’s top border and viewport’s top border intersect, which would cause the element not to be sticky at all if start is also set to 0. A CSS Selector will set the end to the selected element’s bottom border and the element’s bottom border. false will make the element stick until the end of the page. true selects the parent element.

<!-- Sticks until 200px scrolling -->
<div gls-sticky="end: 200"></div>

<!-- Sticks until scrolling the elements height -->
<div gls-sticky="end: 100%"></div>

<!-- Sticks until 20vh scrolling -->
<div gls-sticky="end: 20vh"></div>

<!-- Sticks until the bottom of the selected element -->
<div gls-sticky="end: #my-id"></div>
<div id="my-id"></div>

<!-- Sticks until the bottom of its parent container -->
<div>
    <div gls-sticky="end: true"></div>

        </div>
    </div>

</div>

Offset

To set an offset to the viewport’s edge when the element is sticky, add the offset option. The value can be in vh, % and px. It supports basic mathematics operands + and -.

<div gls-sticky="offset: 200"></div>
  • Stick 200px below the top
  • <div class="gls-background-muted gls-height-large">
    <div class="gls-card gls-card-outline gls-card-body gls-text-center gls-position-z-index" gls-sticky="end: !.gls-height-large; offset: 200">Stick 200px below the top</div>
</div>

Animation

Add an animation from the Animation component in order to have the sticky element reappear smoothly if a start offset is set.

<div gls-sticky="start: 200; animation: gls-animation-slide-top"></div>
  • Animation Slide Top
  • <div class="gls-background-muted gls-height-large">
    <div class="gls-card gls-card-outline gls-card-body gls-text-center gls-position-z-index" gls-sticky="start: 200; end: !.gls-height-large; offset: 80; animation: gls-animation-slide-top">Animation Slide Top</div>
</div>

Show On Up

You can make the sticky element show only when scrolling up to save space. Together with an animation, this makes for a very smooth experience.

<div gls-sticky="show-on-up: true"></div>
  • Slide in on scroll up
  • <div class="gls-background-muted gls-height-large">
    <div class="gls-card gls-card-outline gls-card-body gls-text-center gls-position-z-index" gls-sticky="end: !.gls-height-large; offset: 80; show-on-up: true; animation: gls-animation-slide-top">Slide in on scroll up</div>
</div>

Responsive

It’s possible to disable the sticky behavior for different device widths by applying the media option to the attribute and adding the appropriate viewport width. Add a number in pixel, for example media: 640, or a breakpoint, for example media: @m. The element will be sticky from the specified viewport width and upwards, but not below.

<div gls-sticky="media: 640"></div>
  • Only be sticky on viewports larger than 640px.
  • <div class="gls-background-muted gls-height-large">
    <div class="gls-card gls-card-outline gls-card-body gls-text-center gls-position-z-index" gls-sticky="end: !.gls-height-large; offset: 80; media: 640">Only be sticky on viewports larger than 640px.</div>
</div>

Oversized Content

Sticky content that is larger than the viewport will scroll down and stick to the bottom of the viewport. Changing the scroll direction will immediately scroll the sticky content up and change the sticky behavior to stick to the top of the viewport. Scrolling down will change the behavior again.

Overflow Flip

The overflow-flip option disables the sticky behavior for oversized content. Instead, it only flips the sticky position if the element is larger than the viewport. Changing the scroll direction will not affect the sticky position. Together with the start and end options, two nice sticky effects can be achieved. Cover an element by following content or reveal it by previous content.

<!-- Section will be covered by the next section -->
<div gls-sticky="overflow-flip: true; end: 100%"></div>

<div>Some section.</div>

<!-- Section will be revealed by the previous section -->
<div gls-sticky="position: bottom; overflow-flip: true; start: -100%; end: 0"></div>
  • overflow-flip: true
    end: 100%
    Cover previous section.
    Reveal next section.

Component options

Any of these options can be applied to the component attribute. Separate multiple options with a semicolon. Learn more

Option Value Default Description
position top, bottom top The position the element should be stuck to.
start Length, CSS Selector 0 Start offset. The value can be in vh, % and px. It supports basic mathematics operands + and -. The default value of 0 means that the element’s top border and viewport’s top border intersect. A CSS Selector will set start to the selected element’s bottom border and the element’s top border.
end Length, CSS Selector, Boolean false End offset. The value can be in vh, % and px. It supports basic mathematics operands + and -. A value of 0 means that the element’s top border and viewport’s top border intersect, which would cause the element not to be sticky at all if start is also set to 0. A CSS Selector will set the end to the selected element’s bottom and the element’s bottom border. false will make the element stick until the end of the page. true selects the parent element.
offset Length 0 The offset the Sticky should be fixed to. The value can be in vh, % and px. It supports basic mathematics operands + and -.
overflow-flip Boolean false Flip the Sticky’s position option if the element overflows the viewport and disable overflow scrolling.
animation String false The animation to use when the element becomes sticky.
cls-active String gls-active The active class.
cls-inactive String '' The inactive class.
show-on-up Boolean false Only show sticky element when scrolling up.
media Number, String false Condition for the active status - a width as integer (e.g. 640) or a breakpoint (e.g. @s, @m, @l, @xl) or any valid media query (e.g. (min-width: 900px)).
target-offset false, Length false Initially make sure that the Sticky element is not over a referenced element via the page’s location hash. The offset defines by how far the element will be above the referenced element. false will disable this behavior.

Events

The following events will be triggered on elements with this component attached:

Name Description
