How to keep the elements of different background colors consistent in width?

In web design, it is often encountered that different background color elements need to be displayed side by side and have the same width. Due to style differences such as padding or border, the actual display width may be inconsistent, resulting in visual deviation. The following figure shows this problem:

[The picture should be inserted here, described as: an element with a blue background and an element with a red background side by side, and the width of the blue element is slightly larger than the red element]

In the figure, the blue and red elements are not fixed and inconsistent in width. How to solve it?

An effective way is to remove the inner margin of the blue element and add that inner margin to the red element.

In this way, the width of the content area of ​​the two elements remains consistent, and the visual effect is also achieved. The width of the blue element is determined by the content and borders; the width of the red element is determined by the content, borders and newly added margins. By adjusting the inner margin value, the red element width can be precisely controlled to visually consistent with the blue element.
