How to Maintain Uniform Flex-Item Width After Wrapping
Flexbox offers the ability to create flexible layouts, but when it comes to wrapping flex-items, their widths may vary drastically. To address this issue, let's delve into a clever workaround using CSS media queries.
The Solution
While not strictly a solution, the following approach provides an elegant alternative using media queries and without resorting to JavaScript.
SCSS Mixin
@mixin flex-wrap-fix($flex-basis, $max-viewport-width: 2000px) {
flex-grow: 1;
flex-basis: $flex-basis;
max-width: 100%;
$multiplier: 1;
$current-width: 0px;
@while $current-width < $max-viewport-width {
$current-width: $current-width + $flex-basis;
$multiplier: $multiplier + 1;
@media (min-width: $flex-basis * $multiplier) {
max-width: percentage(1/$multiplier);
}
}
}Usage
Apply the mixin to your flex item:
.flex-item {
@include flex-wrap-fix(100px)
}Advanced Alternative
If your flex container's width is not constrained to the viewport size, you can use element queries instead of browser media queries. Here's a mixin for the flex container:
@mixin flex-container-wrap-items($flex-basis, $max-expected-width: 2000px) {
display: flex;
flex-wrap: wrap;
> * {
max-width: 100%;
flex-grow: 1;
flex-basis: $flex-basis;
}
$multiplier: 1;
$current-width: 0px;
@while $current-width < $max-expected-width {
$current-width: $current-width + $flex-basis;
$multiplier: $multiplier + 1;
&[min-width~="#{$flex-basis * $multiplier}"] > * {
max-width: percentage(1/$multiplier);
}
}
}
Explanation
For each specified flex-basis, we calculate the maximum number of items per row based on the viewport width. We then create media queries to restrict the item's maximum width as a percentage of the viewport width.

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.
