        <form >
        <input type="search" className="search" placeholder='search' />
        <p>filter by type card</p>
        <ul className='filter'>
        <input type="range" className="price-filter" min={0}  max={40}  />

Please post a link to your full project code to make it easier to test your project.

Thank you.

If you move the sticky elements out of the containers they are inside it should work (the offset is relative to its nearest scrolling ancestor/containing block).

It should also work as is if you use position fixed but that will require some more CSS to have the same layout (because the element is now out of flow).
