How to Create Equal-Sized CSS Grid Columns Regardless of Content?

Equally Sized CSS Grid Columns

Many programmers face challenges in achieving equal-width columns in CSS Grid layouts. While Flexbox simplifies this task, this can be accomplished using CSS Grid as well.

The most common approach is to use the repeat() function, as in grid-template-columns: repeat(3, 1fr);. However, this shorthand can be problematic if the content exceeds the track size, as it only distributes available space. To ensure equal width regardless of content size, use the following syntax:

grid-template-columns: repeat(3, minmax(0, 1fr));

The minmax() property allows tracks to be as small as 0 and as large as 1fr, ensuring equal-sized columns. However, note that this may cause overflows if the content is too large or cannot be wrapped.

Here's an example that illustrates the difference:

• repeat(3, 1fr): If content exceeds track size, columns may have uneven widths.
• repeat(3, minmax(0, 1fr)): Columns always remain equal in width, but overflows may occur.
