How to solve the problem of inconsistent width of elements in different background colors?

In web page layout, inconsistent widths of elements of different background colors are a common problem. For example, the difference in widths of elements on red and blue backgrounds is obvious. The following figure shows this problem:

(The picture should be inserted here, and the picture shows the inconsistent width of a red element and a blue element.)

The problem may be due to the padding, margin, or content width difference of the element. The solution is as follows:

First, check and adjust the inner and outer margins of the element. If the inner margin of the blue element is large, causing its visual width to exceed that of the red element, the inner margin of the blue element should be reduced and the inner margin of the red element should be adjusted accordingly to make the visual widths of the two consistent.

If the problem persists after the inner and outer margin adjustments, you need to check the width of the element content. You can use CSS attributes such as width , min-width , or max-width to control the width of the element to ensure that all elements have the same width. Consider using Flexbox or Grid layouts to easily control element width and alignment, and easily solve such problems. By setting width to a fixed or percentage value, you can precisely control the element width.

By adjusting the inner margin, outer margin and CSS width attributes, the problem of inconsistent width of elements in different background colors can be effectively solved, thereby achieving a neat and beautiful web layout.
