Step 3: Add custom CSS
Step 2: Add custom CSS
Custom CSS in Webflow
Curious about where to put custom CSS in Webflow? Ilja explains it in the below video:
CSS
Documentation
This setup is aimed at giving you a super flexible function, with which you can make almost any parallax effect you need for your project. The complete GSAP tween is dynamic, even the actual property that we animate. Below is the list of all available attributes you can use. You don't need to specify every attribute on each parallax trigger. This is important to understand, and the reason we have set default values. Only add the attributes you actually need to override the default for.
data-parallax="trigger"
The main attribute that the code will look for. By default, the element that we 'tag' as the trigger
, will also be the element that we animate, our target. So any other attributes that you want to add, need to go on your trigger
.
data-parallax="target"
Alternatively, if you want to animate a child element of your trigger
, you can give it the target
attribute. All other attributes still need to go on your trigger
. If your trigger
is the element you want to animate, you do not need to add this attribute anywhere.
data-parallax-direction
- Default:
vertical
- Options:
horizontal
orvertical
Controls the property that we animate, so either the xPercent or yPercent of an element. If you want to move an element vertically (along the y-axis) you don't need to add this, the default will rule.
data-parallax-scrub
- Default:
true
- Options: boolean or number
Links the progress of the animation directly to the scrollbar so it acts like a scrubber. Our default is true
because that feels most natural paired with Lenis Scrolling. If you add a number value here, you'll define the amount of seconds it takes for your parallax to "catch up", so data-parallax-scrub="2"
would cause the animation's playhead to take 2 seconds to catch up with the scrollbar's position.
data-parallax-scroll-start
- Default:
top bottom
- Options: String, Number, or Function (See GSAP docs for all info)
This attribute defines when your parallax trigger
or target
will start moving. Our default of top bottom
means the defined target will start moving when the top of the trigger
, reaches the bottom of our screen (so when it starts to enter your viewport). Definitely check out the GSAP docs for the full explanation of this option.
data-parallax-scroll-end
- Default:
bottom top
- Options: String, Number, or Function (See GSAP docs for all info)
Similar to the previous attribute, except this controls when our parallax element will stop moving. Our default of bottom top
means our parallax will stop when the bottom of our trigger, reaches the top of our screen.
data-parallax-start
- Default:
20
- Options: number (including negative)
This is the starting position in % of our target
once your target reaches data-parallax-scroll-start
. This is either for xPercent or yPercent depending on data-parallax-direction
. Example: you have an element with data-parallax-direction="horizontal"
and you add data-parallax-start="35"
. Your target will start 35% to the right of its original position.
data-parallax-end
- Default:
-20
- Options: number (including negative)
This is the end position in % of our target
once it hits the position defined with data-parallax-scroll-end
.
data-parallax-disable
- Default: none
- Options:
tablet
ormobileLandscape
ormobile
If you have a parallax effect that needs to be disabled on smaller breakpoints, you can add data-parallax-disable
to it. We have defined 3 breakpoints for you, but feel free to adjust them for your needs. Since we're working with GSAPs MatchMedia function, we don't have to add our own resize handlers, everything is taken care of. Simply don't add this attribute if your parallax should always run.
Tip for backgrounds:
A common effect for parallax is to have an image, that seems to move inside of a 'mask'. You can see it in our Live Preview link as well. Here's how to do that:
- Create a parent “mask” div with overflow: hidden and give it a position relative. This will be your
data-parallax="trigger"
. - Inside the mask, add a wrapper div that is taller than 100% (e.g. height: 120%). This extra height gives the image room to move without exposing empty space. Give it a position of absolute to sit behind other content.
- Place your image inside that taller wrapper so it completely fills the 120%-high area.
- On the taller, inner wrapper div, add
data-parallax="target"
. - When GSAP animates the target wrapper’s yPercent (or xPercent), the image has 20% extra height to shift into view inside the masked container. The mask (trigger) stays fixed at its original height, hiding any overflow.
- Result: as you scroll, the taller wrapper moves up or down inside the overflow-hidden mask, creating a smooth parallax “image-inside-a-frame” effect without ever showing blank gaps.
