How to Make a Div Vertically Scrollable Using CSS

There are several ways to make a div vertically scrollable using CSS. Here are two possible solutions:

Solution 1: Using the overflow property

One way to make a div vertically scrollable is by using the CSS overflow property. The overflow property specifies what should happen if the content of an element exceeds the size of the element's box.

To make a div vertically scrollable, you can set the overflow property to "auto" or "scroll" for the y-axis. Here's an example:

.scrollable-div {
  height: 200px;
  overflow-y: auto;
}

In the example above, the "scrollable-div" class sets the height of the div to 200 pixels and enables vertical scrolling by setting the overflow-y property to "auto". This will add a scrollbar to the div when its content exceeds the specified height.

Solution 2: Using Flexbox

Another way to make a div vertically scrollable is by using CSS Flexbox. Flexbox is a useful layout system that allows you to create flexible and responsive layouts.

To make a div vertically scrollable using Flexbox, you can use the flex property with the overflow property. Here's an example:

.scrollable-div {
  display: flex;
  flex-direction: column;
  height: 200px;
  overflow-y: auto;
}

In the example above, the "scrollable-div" class sets the display property to "flex" and the flex-direction property to "column". This creates a vertical flex container. The height property sets the height of the div to 200 pixels, and the overflow-y property enables vertical scrolling.

- When using the overflow property, it's important to specify a fixed height or max-height for the scrollable div. Otherwise, the div will expand to fit its content and scrolling won't be necessary.

- If you want to make the entire page vertically scrollable, you can apply the scrollable styles to the body element instead of a specific div.

- If you want to customize the appearance of the scrollbar, you can use CSS pseudo-elements like ::-webkit-scrollbar, ::-webkit-scrollbar-track, ::-webkit-scrollbar-thumb, etc. to style different parts of the scrollbar.

- In some cases, you may need to combine the overflow property with other CSS properties like position: absolute or position: fixed to achieve the desired scrolling behavior.
