How to make Bootstrap navbar sticky on top?
Use the fixed-top class or position: sticky to enable the navigation bar to fix the top. Bootstrap provides a fixed-top class, which can be fixed by adding directly to the navbar, but you need to add padding-top to the body to avoid the content being blocked; if you need more flexible control, you can set position: sticky, top value and z-index by custom CSS; in addition, you need to note that the parent container cannot have overflow: hidden, top value must be set, and z-index is recommended; common problems include style overlay, element overlap, and the incorrect introduction of CSS files. It is recommended to use developer tools to troubleshoot style application and avoid naming conflicts.
Sometimes we want the navigation bar to always be fixed at the top when the page is scrolling, so that users can click on the menu at any time without having to scroll back. Bootstrap itself has provided ready-made classes to implement this function, which can be done by just using it correctly.
Quick implementation using fixed-top class
Bootstrap provides a very convenient class: fixed-top , which can be fixed on the top by adding it directly to the navbar.
<nav class="navbar navbar-expand-lg navbar-light bg-light fixed-top"> <!-- Navigation Content--> </nav>
After doing this, the navigation bar stays at the top no matter how you scroll the page. But it should be noted that since the navigation bar is separated from the document stream, the content below it may be obscured. The solution is to add a padding-top to body or main content area, and the value is roughly equal to the height of the navigation bar (usually 56px):
body {
padding-top: 56px;
}This way the page content will not be blocked.
Custom style or behavior
If you don't want to use the default style of Bootstrap, or want to control sticky positioning more flexibly, you can also write CSS yourself using position: sticky :
.my-sticky-nav {
position: sticky;
top: 0;
z-index: 1020;
background-color: white; /* Avoid transparent background affecting display*/
}Then add the class name to your navbar:
<nav class="navbar navbar-expand-lg navbar-light bg-light my-sticky-nav"> <!-- Navigation Content--> </nav>
The advantage of this method is that it can control the position and conditions of "stickiness" more carefully, such as taking effect only within the scope of a certain container.
But a few things to note:
- The parent element cannot have
overflow: hidden, otherwise sticky will not take effect -
topvalue must be set, otherwise it will not work - It is recommended to set
z-indexto ensure that the level is high enough
Notes and FAQs
Sometimes you will find that the navigation bar is missing after setting fixed-top , or the style is inconsistent, which may be caused by the following reasons:
- The page structure is not processed well, such as multiple fixed positioning elements overlap
- The padding of the body is not set, causing the content to be blocked
- Custom styles are used to override Bootstrap default styles
Suggested practices:
- First confirm whether the correct Bootstrap CSS file has been introduced
- Check whether the elements in the browser developer tool have the expected style applied
- If you use your own style, pay attention to naming conflict issues
Basically these are the methods. Using fixed-top is the fastest way. If you need more control, you can use position: sticky to write the style yourself. Both are not complicated, but details are easy to ignore, especially the issue of layout and cascade order.

How to use Bootstrap forms?

Horizontal forms are displayed in line with labels and controls by combining grid systems (such as col-sm-*), and inline forms use practical classes such as d-flex to replace the removed form-inline in Bootstrap5; 3.
