Changing the style of bootstrap.css

I need to make modifications to an HTML page that is using bootstrap.css. The specific line I am focusing on is 

        <input type="submit" class="btn btn-primary btn-block btn-md" value="Create">

This points to 

.btn {
  display: inline-block;
  *display: inline;
  padding: 4px 12px;
  margin-bottom: 0;
  *margin-left: .3em;
  font-size: 24px;
  line-height: 20px;
  ..
}

within the bootstrap.css file. Despite adjusting the font-size, I do not see any changes reflected in the browser after refreshing. What could be causing this issue?

Answer №1

It is advised not to alter the default CSS file of Bootstrap as it can lead to potential issues. Instead, create your own CSS file and utilize it to override the default styles.

To do this, simply create a new file named myown.css and include it in your project after the Bootstrap CSS file.

This approach allows you to customize the styles without needing to use !important, which is discouraged when working with frameworks.

Answer №2

Avoid altering any library files as it is considered bad practice. Instead, create a copy of the styles and add them to your local style sheets. To ensure that your styles take precedence over those in 'bootstrap.css', you can use the !important rule.

.btn {
  font-size: 24px !important;
}
