Why are the inline-block elements misaligned? How to solve this problem?

Inline-block element misalignment problem and coping strategies

In web page layout, the misalignment of inline-block elements occurs from time to time, causing a lot of trouble to front-end developers. This article will analyze the causes of this problem and provide effective solutions.

Problem phenomenon

Assume that the HTML structure is as follows, including two inline-block elements:

<div>
    <span class="desc">11<br> twenty two<br> 33<br> 44</span>
    <span>Other content</span>
</div>

CSS style:

 span {
    display: inline-block;
}
.desc {
    overflow: hidden;
}

After the .desc element is set to overflow: hidden , the second span element may experience vertical misalignment.

The root cause of dislocation

The misalignment problem stems from the baseline alignment mechanism of the inline-block element. overflow: hidden attribute will affect the baseline position of the element, resulting in deviations when the subsequent inline-block element is aligned with the previous element's baseline.

Effective solution

This problem can be solved by adjusting the vertical-align attribute. Modified CSS code:

 .desc {
    display: inline-block;
    width: 80px;
    height: 80px;
    overflow: hidden;
    vertical-align: middle; /* key modification*/
}

span {
    display: inline-block;
    vertical-align: middle; /* key modification*/
}

Set vertical-align to middle to align all inline-block elements with a vertical midline, avoiding misalignment caused by baseline alignment.

Through the above analysis and solutions, we can effectively avoid the problem of inline-block element misalignment and improve the accuracy and aesthetics of web page layout.
