Let’s stick the footer to the bottom when page content is less. Just one CSS class solves the problem.
The first step is to make sure your website layout consists of 3 containers (header – content – footer) that will make our life easier. because the problem is when the page content is less than the height of the screen viewport, the footer moves up. So what we need to do is to give the content container a minimum height that equals the viewport height subtracted by the header container and footer container. The CSS calc function will help us with that equation.
.min-h-for-page-content {
min-height: calc(100vh - 60px - 148px);
}100vh: the viewport height is 100%- 60px: The header height, it can be changed as you want
- 148px: the footer height,
All you need to do is to use this class min-h-for-page-content with the page content container.
Here is an example with Bootstrap.
This an album example made by bootstrap 5, we stuck the footer to the bottom with our new CSS class
.min-h-content{
min-height: calc(100vh - 56px - 148px);
