How to Remove Margins from the Last Element in a Row When Row Size Varies?

How to Remove Margins from Last Elements in a Row (Regardless of Row Size)

In situations where you have multiple elements in a row, and the number of elements per row may vary dynamically, removing margins from the last element in each row can be challenging using pure CSS.

Using Negative Margins

One effective technique is to use negative margins on the parent element. This creates the illusion that child elements fit perfectly within the parent while maintaining spacing between them.

<code class="css">ul {
    margin-left: -5px;
    margin-right: -5px;
}

li {
    margin-left: 5px;
    margin-right: 5px;
}</code>

By splitting the margin and applying it to both sides, you can achieve better results, especially for designs that require compatibility with both left-to-right (LTR) and right-to-left (RTL) orientations.

Utilizing Media Queries

Another approach, if you can predict the number of elements per row within specific screen sizes, is to use media queries to target last elements in rows using nth-child(). This method allows for more specific styling adjustments:

<code class="css">@media (min-width: 400px) and (max-width: 499px) {
    li:nth-child(even) {
        margin-right: 0;
        border-right: none;
    }
}

@media (min-width: 500px) and (max-width: 599px) {
    li:nth-child(3n+3) {
        margin-right: 0;
        border-right: none;
    }
}

/* Add more media queries as needed... */</code>
