Scroll code in css

Making a div vertically scrollable using CSS

gives a div that the user can scroll in both in horizontally and vertically. How do I change it so that the div is only scrollable vertically?

You have it covered aside from using the wrong property. The scrollbar can be triggered with any property overflow , overflow-x , or overflow-y and each can be set to any of visible , hidden , scroll , auto , or inherit . You are currently looking at these two:

• auto — This value will look at the width and height of the box. If they are defined, it won’t let the box expand past those boundaries. Instead (if the content exceeds those boundaries), it will create a scrollbar for either boundary (or both) that exceeds its length.
• scroll — This values forces a scrollbar, no matter what, even if the content does not exceed the boundary set. If the content doesn’t need to be scrolled, the bar will appear as «disabled» or non-interactive.

If you always want the vertical scrollbar to appear:

You should use overflow-y: scroll . This forces a scrollbar to appear for the vertical axis whether or not it is needed. If you can’t actually scroll the context, it will appear as a»disabled» scrollbar.

If you only want a scrollbar to appear if you can scroll the box:

Just use overflow: auto . Since your content by default just breaks to the next line when it cannot fit on the current line, a horizontal scrollbar won’t be created (unless it’s on an element that has word-wrapping disabled). For the vertical bar,it will allow the content to expand up to the height you have specified. If it exceeds that height, it will show a vertical scrollbar to view the rest of the content, but will not show a scrollbar if it does not exceed the height.

using overflow: auto somehow creates a gigantic empty block of space at the bottom of the page. Is this a common occurrence?

if you set the overflow-y value to ‘auto’, the scroll will be visible after defined height. for example

For 100% viewport height use:

overflow: auto; max-height: 100vh; 

Use overflow-y: auto; on the div.

Also, you should be setting the width as well.

@LeeGee you need width to calculate whether the content of the div has gone outside the div boundaries and thus whether to enable scroll or not.

You can use this code instead.

overflow-x: The overflow-x property specifies what to do with the left/right edges of the content — if it overflows the element’s content area.
overflow-y: The overflow-y property specifies what to do with the top/bottom edges of the content — if it overflows the element’s content area.

Values
visible: Default value. The content is not clipped, and it may be rendered outside the content box.
hidden: The content is clipped — and no scrolling mechanism is provided.
scroll: The content is clipped and a scrolling mechanism is provided.
auto: Should cause a scrolling mechanism to be provided for overflowing boxes.
initial: Sets this property to its default value.
inherit Inherits this property from its parent element.

You can use overflow-y: scroll for vertical scrolling.

How TO — Custom Scrollbar

Note: Custom scrollbars are not supported in Firefox or in Edge, prior version 79.

How To Create Custom Scrollbars

Chrome, Edge, Safari and Opera support the non-standard ::-webkit-scrollbar pseudo element, which allows us to modify the look of the browser’s scrollbar.

The following example creates a thin (10px wide) scrollbar, which has a grey track/bar color and a dark-grey (#888) handle:

Example

/* width */
::-webkit-scrollbar width: 10px;
>

/* Track */
::-webkit-scrollbar-track background: #f1f1f1;
>

/* Handle */
::-webkit-scrollbar-thumb background: #888;
>

/* Handle on hover */
::-webkit-scrollbar-thumb:hover background: #555;
>

This example creates a scrollbar with box shadow:

Example

/* width */
::-webkit-scrollbar width: 20px;
>

/* Track */
::-webkit-scrollbar-track box-shadow: inset 0 0 5px grey;
border-radius: 10px;
>

/* Handle */
::-webkit-scrollbar-thumb background: red;
border-radius: 10px;
>

Scrollbar Selectors

For webkit browsers, you can use the following pseudo elements to customize the browser’s scrollbar:

• ::-webkit-scrollbar the scrollbar.
• ::-webkit-scrollbar-button the buttons on the scrollbar (arrows pointing upwards and downwards).
• ::-webkit-scrollbar-thumb the draggable scrolling handle.
• ::-webkit-scrollbar-track the track (progress bar) of the scrollbar.
• ::-webkit-scrollbar-track-piece the track (progress bar) NOT covered by the handle.
• ::-webkit-scrollbar-corner the bottom corner of the scrollbar, where both horizontal and vertical scrollbars meet.
• ::-webkit-resizer the draggable resizing handle that appears at the bottom corner of some elements.

CSS Layout — Overflow

The CSS overflow property controls what happens to content that is too big to fit into an area.

This text is really long and the height of its container is only 100 pixels. Therefore, a scrollbar is added to help the reader to scroll the content. Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat. Duis autem vel eum iriure dolor in hendrerit in vulputate velit esse molestie consequat, vel illum dolore eu feugiat nulla facilisis at vero eros et accumsan et iusto odio dignissim qui blandit praesent luptatum zzril delenit augue duis dolore te feugait nulla facilisi. Nam liber tempor cum soluta nobis eleifend option congue nihil imperdiet doming id quod mazim placerat facer possim assum. Typi non habent claritatem insitam; est usus legentis in iis qui facit eorum claritatem.

CSS Overflow

The overflow property specifies whether to clip the content or to add scrollbars when the content of an element is too big to fit in the specified area.

The overflow property has the following values:

• visible — Default. The overflow is not clipped. The content renders outside the element’s box
• hidden — The overflow is clipped, and the rest of the content will be invisible
• scroll — The overflow is clipped, and a scrollbar is added to see the rest of the content
• auto — Similar to scroll , but it adds scrollbars only when necessary

Note: The overflow property only works for block elements with a specified height.

Note: In OS X Lion (on Mac), scrollbars are hidden by default and only shown when being used (even though «overflow:scroll» is set).

overflow: visible

By default, the overflow is visible , meaning that it is not clipped and it renders outside the element’s box:

You can use the overflow property when you want to have better control of the layout. The overflow property specifies what happens if content overflows an element’s box.

Example

overflow: hidden

With the hidden value, the overflow is clipped, and the rest of the content is hidden:

You can use the overflow property when you want to have better control of the layout. The overflow property specifies what happens if content overflows an element’s box.

Example

overflow: scroll

Setting the value to scroll , the overflow is clipped and a scrollbar is added to scroll inside the box. Note that this will add a scrollbar both horizontally and vertically (even if you do not need it):

You can use the overflow property when you want to have better control of the layout. The overflow property specifies what happens if content overflows an element’s box.

Example

overflow: auto

The auto value is similar to scroll , but it adds scrollbars only when necessary:

You can use the overflow property when you want to have better control of the layout. The overflow property specifies what happens if content overflows an element’s box.

Example

overflow-x and overflow-y

The overflow-x and overflow-y properties specifies whether to change the overflow of content just horizontally or vertically (or both):

overflow-x specifies what to do with the left/right edges of the content.
overflow-y specifies what to do with the top/bottom edges of the content.

You can use the overflow property when you want to have better control of the layout. The overflow property specifies what happens if content overflows an element’s box.

Example

div <
overflow-x: hidden; /* Hide horizontal scrollbar */
overflow-y: scroll; /* Add vertical scrollbar */
>
