Html Question posted in
Some basic documentation can be found here.

down Why doesn’t my sidebar stay at the top when I scroll down HTML?

I tried to make my sidebar sticked at the top when everytime I scrolled but I dunno why it won’t stick at the top.

Here’s what I did and I expect it to sticked at the top when scrolled.

See my code below:

<section id="blog" class="blog">
      <div class="container">

        <div class="row">
          <div class="col-lg-8">...</div>

          <div class="col-lg-4">
            <div class="sidebar">
              I'm trying to stick this column at the top when scrolled.
            </div>
          </div>
        </div>

      </div>
    </section>

CSS:
.blog .sidebar {
  position: sticky;
  top: 0;
  right: 0;
  overflow-y: auto;
}

    The <section> needs to be sticky as well.

    .blog, .blog .sidebar {
  position: sticky;
  top: 0;
  right: 0;
  overflow-y: auto;
}
    <section id="blog" class="blog">
  <div class="container" >

    <div class="row">
      <div class="col-lg-8">...</div>

      <div class="col-lg-4">
        <div class="sidebar">
          I'm trying to stick this column at the top when scrolled.
        </div>
      </div>
    </div>

  </div>
</section>
<div style="height: 200vh">
    For testing...
</div>

    It really depends on what that row class is doing. For example if it’s a flex container that displays its child elements in a row like the example below then your sticky rule will work (with a minor adjustment).

    .row { display: flex; justify-content: space-between;}
.main, .sidebar { padding: 0.25rem; border: 1px solid #555; border-radius: 5px; }
.main { height: 200vh; width: 80%; top: 10px; }
.sidebar { margin-left: auto; position: sticky; top: 10px; width: 80%; }
    <section id="blog" class="blog">
  <div class="container">
    <div class="row">
      <div class="col-lg-8 main">"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure

        </div>
      </div>
    </div>
  </div>
</section>

    your problem is you don’t have a parent element with position: relative. so to solve your problem you need to set:

    .blog {
  position: relative;
}

    and sidebar:

    .sidebar {
  position: sticky;
  top: 0;
  right: 0;
  overflow-y: auto;
}

    hope it will help you. Let me know the result
