How to change the right margin of the vertical scroll bar in CSS
The sample code is as follows:
/* CSS */
::-webkit-scrollbar {
width: 10px;
margin-right: 20px; /* Set the right margin to 20px */
}
::-webkit-scrollbar-thumb {
background-color: #ccc;
border-radius: 5px;
}
::-webkit-scrollbar-track {

}
2. Using the scrollbar-width Property
In Firefox, you can use the scrollbar-width property to control the width of the scrollbar, thereby changing the right margin of the scrollbar.
The sample code is as follows:
/* CSS */
body {
scrollbar-width: thin;
scrollbar-color: #ccc #f1f1f1;
margin-right: 20px; /* Set the right margin to 20px */
}
3. Use JavaScript to Dynamically Calculate the Right Margin
If you need to dynamically calculate the right margin of the scrollbar based on the width of the page content, you can use JavaScript to achieve this.
Sample code is as follows:
<!-- HTML -->
<div id="content">

</div>
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Set the initial right margin to 20px */
}
// JavaScript
window.onload = function() {
var content = document.getElementById('content');
var scrollbarWidth = content.offsetWidth - content.clientWidth;
content.style.marginRight = scrollbarWidth + 'px'; // Dynamically calculate the right margin
}
The above example code allows you to dynamically calculate the right scrollbar margin based on the content width.
4. Using the calc() Function
In CSS, you can use the calc() function to perform mathematical calculations, allowing for more flexible styling.
The sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: calc(20px + 10%); /* Set the right margin to 20px + 10% */
}
Using the calc() function, you can dynamically calculate the right scrollbar margin based on percentages.
5. Using the @media Query
In responsive design, you can use the @media query to set different right scrollbar margins based on different screen sizes.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
@media screen and (max-width: 768px) {
margin-right: 10px; /* Set right margin to 10px on small screens */
}
}
Using the @media query, you can set different right scrollbar margins for different screen sizes.
6. Using position: sticky
In some cases, you can use position: sticky to achieve a fixed right scrollbar margin.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
position: sticky;
right: 0; /* Set right margin to 0 */
}
Using the position: sticky property, you can achieve a fixed right scrollbar margin.
7. Using the float Property
In some special cases, you can use the float property to adjust the right margin of the scrollbar.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
float: right; /* Set right float */
}
The float property can be used to adjust the right margin of the scrollbar.
8. Using Flexbox Layout
When using flexbox layout, you can adjust the right scrollbar margin by setting the flex-grow property.
Sample code is as follows:
/* CSS */
#container {
display: flex;
}
#content {
flex-grow: 1;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* The default right margin is 20px */
}
Using the flex-grow property, you can adjust the right scrollbar margin in a flexbox layout.
9. Using grid Layout
When using a grid layout, you can adjust the right scrollbar margin by setting the grid-template-columns property.
Sample code is as follows:
/* CSS */
#container {
display: grid;
grid-template-columns: 1fr auto; /* Set the right margin to auto */
}
#content {
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
}
The grid-template-columns property allows you to adjust the right scrollbar margin in a grid layout.
10. Using the overflow Property
In some special cases, you can adjust the right scrollbar margin by setting the overflow property.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
overflow: hidden; /* Set overflow content to be hidden */
}
By setting the overflow property, you can adjust the right scrollbar margin.
11. Using the padding-right Property
In addition to directly setting the margin-right property, you can also adjust the right scrollbar margin by setting the padding-right property of the parent element.
Sample code is as follows:
/* CSS */
#container {
padding-right: 20px; /* Set the parent element's right padding to 20px */
}
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
}
By setting the parent element’s padding-right property, you can indirectly adjust the scrollbar’s right padding.
12. Using the box-sizing Property
In some cases, you can adjust the scrollbar’s right padding by setting the box-sizing property.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
box-sizing: border-box; /* Set the box model to border-box */
}
By setting the box-sizing property to border-box, you can adjust the right scrollbar margin.
13. Using the transform Property
In some special cases, you can adjust the right scrollbar margin by setting the transform property.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
transform: translateX(20px); /* Horizontal translation 20px */
}
By setting the transform property, you can adjust the right margin of the scroll bar.
14. Using position: absolute
In some special cases, you can adjust the right margin of the scroll bar by setting position: absolute.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
position: absolute;
right: 20px; /* Set right margin to 20px */
}
By setting the position: absolute property, you can adjust the right margin of the scroll bar.
15. Using the z-index Property
In some special cases, you can adjust the right margin of the scroll bar by setting the z-index property.
Sample code is as follows:
/* CSS */
#content {
width: 500px;
height: 200px;
overflow-y: scroll;
margin-right: 20px; /* Default right margin is 20px */
position: relative;
z-index: 1; /* Set level to 1 */
}
By setting the z-index property, you can adjust the right margin of the scrollbar.
