'Override bootstrap font size

I am using Bootstrap v5.0.2 but I need to override the font size to some custom value.

In the html I am using <a href="#" class="btn btn-outline-danger">Click</a> This gives me some predefined button sizes. In my main .css file I have:

body{font-size: 22px;}
h1{font-size: 24px;}

I want to match the button font size to the the page font size.

What is the best way to override the font size of the button?

I would add a class in your main css file . For Example

.pageButtonSize {  font-size: 22px !important; }

and then add the class to your button markup.

<a href="#" class="btn btn-outline-danger pageButtonSize">Click</a>

If you want the custom size applied to all .btns then in a stylesheet loaded after BS override the body font size by setting the value of the CSS variable and the .btn font size to use the variable:

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous">

<style>
  h1 {
    font-size: 24px;
  }
  
  body {
    --bs-body-font-size: 22px;
  }
  
  .btn {
    font-size: var(--bs-body-font-size);
  }
</style>
<h1>
  heading
</h1>
<p>
  paragraph
</p>
<button class="btn btn-primary">
  button
</button>

This will adjust the font size of any element that is based on the var(--bs-body-font-size) value. There is no need to use !important nor an additional class name (on every single .btn).

you can create your own file.css containing all styles you want to override

then, add this file to your project after bootstrap is added

Note: to make sure your styles will be applied, consider adding !important for each style for example:

h1{
  font-size: 50px !important;
  }
