Implementing Vertical Flexbox Space Filling
Problem:
Within a flexbox row, it's possible to designate a specific element to fill the available horizontal space using the flex property. However, achieving the same behavior vertically has proven challenging, as the element designated to fill the space lacks height.
Question:
Is there a way to utilize flexbox to have a content element fill the remaining vertical space within a flexbox column, similar to how it can be done in a flexbox row?
Answer:
Yes, by employing the following two modifications:
- Set flex-direction: column for the flex container.
- Assign flex: 1 to the element that should occupy the remaining vertical space.
By applying these techniques, you can ensure that the specified element extends to the bottom of the flex container, effectively filling the available vertical space.
Example:
Consider the following code snippet, which demonstrates how this approach can be implemented in practice:
<div class="row"> <div>some content</div> <div class="flex">This fills the available space</div> <div>another content</div> </div>
body {
margin: 0;
}
*{
box-sizing: border-box;
}
.row {
display: flex;
flex-direction: column;
height: 100vh;
}
.flex {
flex: 1;
}
.row, .row > * {
border: 1px solid;
}
By setting flex-direction: column for the parent container and flex: 1 for the desired element, we effectively create a flexbox layout that fills the vertical space as intended.
This approach eliminates the need for absolute positioning, providing a more elegant and flexible solution for filling vertical space in flexbox layouts.

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.
