Extending Bootstrap Row Beyond Container
Problem Description
Bootstrap's grid system provides a convenient way to create responsive layouts. However, in some instances, you may encounter situations where you need an element to extend beyond the container's width. This can present challenges in achieving the desired design.
Solution
Option 1: Using CSS Pseudo Element
Create a pseudo ::before element with a negative left offset extending past the container's width. This element will act as a spacer that pushes the target element beyond the container.
#main {
background: lightgreen;
height: 100vh;
}
#main > .row {
height: 100vh;
}
.left {
background: red;
position: relative;
top: 50%;
transform: translateY(-50%);
}
.left:before {
left: -999em;
background: red;
content: '';
display: block;
position: absolute;
width: 999em;
top: 0;
bottom: 0;
}
Option 2: Using Absolute Positioned Container
Use a container-fluid with absolute positioning that extends to the screen edges behind the primary container acting as a "ghost" container.
.abs {
position: absolute;
right:0;
top:0;
bottom:0;
z-index: 1;
}

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.
