Position: sticky doesn't seem to work for me when I apply it to a child of a div. How to solve?

HTML:

Lorem Ipsum
<div class="this-parent-div-is-necessary">
   <div class="div-sticky-class">
     Test
   </div>
</div>
Lorem Ipsum

CSS:

.div-sticky-class{
  color: red;
  position: sticky;
  position: -webkit-sticky;
  top: 0;
}

  • Can you share more of your CSS; such as the parent `div` CSS? `overflow:auto` in a parent element prevents `sticky` from functioning in Safari. I assume Safari is a concern based on your use of `-webkit-sticky` – Robert Jul 20 '17 at 17:48

    You'll need javascript for this or get rid of the parent somehow. firefox understands `display:contents` https://jsfiddle.net/n8Le2tva/1/ but what's the point ? `display:inline` would do too https://jsfiddle.net/n8Le2tva/2/ – G-Cyrillus Jul 20 '17 at 17:48
  • @Bob Here https://jsfiddle.net/n8Le2tva/3/ add `br`s inside of the parent, your parent is too short for it to stick, it is sticky relative to the parent div – Huangism Jul 20 '17 at 17:51
  • @GCyrillus, two fantastic solution, but they don't work on Safari... – Bob Jul 20 '17 at 17:54
  • then, mind javascript to take care of it. it is the most solid way at this time :) – G-Cyrillus Jul 20 '17 at 17:56
  • @GCyrillus thank you, I will use Javascript :( – Bob Jul 20 '17 at 17:59
  • @Bob what are you trying to achieve? It doesn't look like you need js – Huangism Jul 20 '17 at 18:09

Your sticky element is working as intended, you can't see it because your container div is as short as the sticky element itself, so as soon as it sticks, the parent container is already scrolled out of view.

If you add the br tags inside of the parent div then you can see it stick. Once you scroll past the parent then it will scroll with the parent and will not be visible anymore as you can see from your original fiddle. Example on this page https://developer.mozilla.org/en/docs/Web/CSS/position

If you are trying to dock this for the entire page then you just need to place the sticky element under a higher level div, for example a div that contains all page content. Just remember when it sticks it only sticks within the parent container

HTML

<div class="this-parent-div-is-necessary">
  <div class="div-sticky-class">
      Test
  </div>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/>
</div>

This example here https://jsfiddle.net/n8Le2tva/10/ I moved the sticky element out so it sticks to the overall viewport

    Not sure about you but I can't help to cringe seeing all those `
    `s , even in a demo. You can just do `

    lorem1000

    `+TAB instead. Then delete the paragraph once done testing. Just sayin'.

  • @GustvandeWal None really, it's just Emmet, the code completion toolkit: https://emmet.io/ - Most text editors already come with it. FWIW, I use Sublime Text. – Ricardo Zea Dec 09 '19 at 20:22

Put everything inside your this-parent-div-is-necessary container.

.div-sticky-class {
  color: red;
  position: sticky;
  position: -webkit-sticky;
  top: 0;
}
<div class="this-parent-div-is-necessary">
  Lorem Ipsum
  <div class="div-sticky-class">
    Test
  </div>
  Lorem Ipsum
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
  <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
</div>

Sticky position only works inside the parent div, your html should be like this:

Lorem Ipsum
<div class="this-parent-div-is-necessary">
   <div class="div-sticky-class">
     Test
   </div>
   <div>Lorem ...</div>
   <div>Lorem ...</div>
   <div>Lorem ...</div>
   <div>Lorem ...</div>
   <div>
     <p>It will works here too</p>
   </div>
</div>
Won't work here because it's outside the parent of div-sticky-class
<br/><br/><br/><br/><br/><br/><br/><br/><br/>

Well it is actually working .But the div with class div-sticky-class is inside another div (with class this-parent-div-is-necessary ) that moves. Well if you want it to work you can give the outer div the same class e.g

Lorem Ipsum
<div class="this-parent-div-is-necessary div-sticky-class">
  <div class="div-sticky-class">
      Test
  </div>
</div>
Lorem Ipsum

Most likely you are wanting to apply sticky to the nav links of a header but not the logo itself.

<header>
  <img src="/logo.svg" alt="Logo"/>
  <ul>
     <li><a href="/">Home</a></li>
     <li><a href="/">About</a></li>
     <li><a href="/">Contact</a></li>
  </ul>
</header>

Here is potential css you can use.

header {
  position: sticky;
  top: -100px;
}

This way, the bottom part of your header is the part that appears sticky!

The top value would have to be calculated by JS if your image does not have a fixed size. Then, you can find the ul and set the top attribute to the img's negative height.

Of course, on desktop view, you would most likely want the whole header element sticky, with the img, so on your desktop layout width's just set top to 0 with css breakpoints.
