How to create a fixed sidebar layout with Bootstrap?
Using Bootstrap to create a fixed sidebar layout requires a combination of the grid system and custom CSS. 1. Use container-fluid, row and col-* classes to divide the sidebar and the main content area; 2. Fix the sidebar through position:fixed, and set properties such as top, bottom, z-index to make it always visible; 3. The main content area uses margin-left to avoid the sidebar; 4. Use response classes such as d-md-block to hide the sidebar on small screens, and can be used with offcanvas to achieve mobile folding. Getting the width and margins right is key.

How to override Bootstrap default CSS styles?
First, load the custom CSS file after Bootstrap in HTML to ensure style priority; second, override the default style by increasing selector specificity (such as using parent elements to qualify or combine class names); if necessary, you can use the !important statement to force it to take effect, but you should be careful to avoid abuse; it is recommended to combine with the Sass preprocessor to modify variable values before introducing Bootstrap to achieve in-depth customization. This method effectively and neatly overrides Bootstrap default styles.

How to change the number of columns in the Bootstrap grid?
The answer is: Bootstrap uses a 12-column grid system by default. Different layouts can be achieved by adjusting column span classes such as col-md-4 without changing the total number of columns. If you need to customize the number of columns, you can modify the Sass variable $grid-columns and recompile the CSS.
