Overflow Scroll CSS Is Not Working in the Div

overflow-y: scroll not working, showing style but cannot be scrolled?

There is no need to scroll.

The browser will only scroll if the content within the div needs to scroll in order to see more items in the ul. To make the scroll bar appear only if it needs to be there, you can use overflow-y: auto.

You implicitly tell the browser to show to the scroll bar even though it's not needed with such little ul elements. Try adding more elements to see the scroll bar work properly.

.list {
    margin: auto;
    height: 285px;
    width: 300px;
    overflow-y: auto; /* This changed */
}

<div class="list">
    <ul>
        <li> hello world </li>
        <li> hello jupiter </li>
        <li> hello mars </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello world </li>
        <li> hello jupiter </li>
        <li> hello mars </li>
    </ul>
</div>

Deleting some of those li elements will cause the scroll bar to shrink until it is not needed anymore.

overflow-y scroll not working for ul nested in div

Remove overflow-y: hidden from the div container element.

Add an explicit height to the ul.

div {
  background-color:#FFFFEE;
  width: 200px;
  height: 100px;
  //overflow-y: hidden;
}

ul {
  height: 100px;
  overflow-y:scroll;
}

Should do the trick.

CSS overflow not working as expected and unable to scroll to bottom of div

The problem is with BelowNavContainer Component.

You've set its height to 100vh, but notice that there is header above it, so the total height of the full page now is :

header Height + 100vh(BelowNavContainer height).

and as you put thier parent component: ProjectContainer height to 100%, overflow: hidden, this will hide the bottom of the DashboardBody' component.

Solution:

to put height of BelowNavContainer as follows:
height: calc(100vh - 100px)

as 100px:is the hieght of your header

you can see this wrking demo

Overflow Scroll css is not working in the div as expected

If you want the vertical scrollbar to apply to just the scrollable content, you can put everything into a container that’s set to the full viewport height, and then use flex to have a second container that’s used for the content to fit the space left after the navbar. Applying overflow: auto to the second container will give it a scrollbar like your illustration.

body {
    margin: 0;
    padding: 0;
}
.container {
    height: 100vh;
    display: flex;
    flex-direction: column;
}
.nav {
    padding: 1rem;
    background-color: blue;
}

.content {
    padding: 1rem 35%;
    overflow: auto;
    flex-grow: 1;
    font-size: large;
}

<div class="container">
    <div class="nav">
        <h1>Nav content</h1>
    </div>
    <div class="content">

Overflow-y auto not working in this case

You must give perfect height to the content element in order for the scroll to work.

height: calc(100vh - 24px - 40px - 40px);

html {

  height: 100%;

}

body {

  font-family: 'Open Sans';

  font-weight: 300;

  font-size: 20px;

  color: #3d5266;

  margin: 12px;

  background: lightblue;

}

#container {

  max-width: 800px;

  position: relative;

  overflow: hidden;

  max-height: calc(100vh - 24px);

  border-radius: 6px;

  box-shadow: 0 1px 3px 1px rgba(0,0,0,0.2);

  margin: auto;

}

header, footer {

  position: absolute;

  width: 100%;

  height: 40px;

  line-height: 40px;

  background: #fff;

  z-index: 5;

  outline: 1px solid rgba(0,0,0,0.1);

  padding: 0 8px 0 8px;    

}

header {

  top: 0;

  border-radius: 6px 6px 0 0;  

}

footer {

  bottom: 0;  

  border-radius: 0 0 6px 6px; 

}

section {

  margin: 40px 0;

}

.content {

  position: relative;

  height: calc(100vh - 24px - 40px - 40px);

  overflow-y: auto;

  overflow-x: hidden;

  background: #fff;

  padding: 8px;

}

</style>

Setting overflow to scroll on fixed div doesn't work

Problem solved.
Using min-height keeps the menu render forever but when used height only scroll works perfectly.

Nested div will not scroll

If you set 100% at your height property from .items class, your <div> tag will expand until all nested items are shown. To enable your scroll , the height of the <div> with class .items must be lower to what it would have if your div expanded to accommodate all nested tags.

Try to set your height property lower than 100% or set in pixels (100px, for instance).
