Bootstrap 3 Full-Height Columns: A Custom CSS Solution
Introduction:
Creating full-height layouts with Twitter Bootstrap 3 can be challenging. While Bootstrap's native classes do not support this feature, it is possible to achieve this effect using custom CSS.
Custom CSS Approach:
-
Setting 100% Height:
Set the height of the body, container, and row elements to 100% to ensure that they span the full height of the viewport. -
Displaying as a Table:
Convert the container element into a table using display: table. This allows the contents of the container to be arranged in a tabular structure. -
Floating Cell:
Add a custom class, such as no-float, to the navigation column. Set this class to have display: table-cell and float: none. This will prevent the navigation column from floating and allow it to vertically align with the content column.
Markup:
<header>Header</header>
<div class="container">
<div class="row">
<div class="col-md-3 no-float">Navigation</div>
<div class="col-md-9 no-float">Content</div>
</div>
</div>
CSS:
html, body, .container {
height: 100%;
}
.container {
display: table;
width: 100%;
margin-top: -50px;
padding: 50px 0 0 0;
}
.row {
height: 100%;
display: table-row;
}
.row .no-float {
display: table-cell;
float: none;
}
Advantages and Considerations:
- This custom CSS solution provides a full-height layout that is compatible with Bootstrap 3.
- The 1:3 ratio of navigation to content can be adjusted by modifying the column widths in the CSS.
- However, it's important to use the custom class (e.g., no-float) instead of modifying Bootstrap's native column classes to avoid conflict.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
