I used display:inline-block; when making H5 horizontal sliding cards, but found that there were gaps between elements on the same horizontal line. This was obviously not the effect I wanted, so I I changed it to left floating, which solved the problem of gaps, but the width of the parent element needs to be set to achieve horizontal left and right scrolling, which increases the amount of code. Because the number of cards is not fixed, the width of its parent element needs to be set in real time. Width requires js, so the amount of code increases, which is not the best choice. It seems that the best solution is to use display:inline-block;, so the gap problem arises. The code is as follows:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
<title>document</title>
<style>
*{margin:0;padding:0;}
.box{overflow-x:auto;background:#fff;white-space:nowrap;}
.box span{display:inline-block;width:100px;height:30px;line-height:30px;text-align:center;background:#f00;color:#fff;}
</style>
</head>
<body>
<p class="box">
    <span>111</span>
    <span>111</span>
    <span>111</span>
    <span>111</span>
</p>
</body>
</html>

The effect is as follows:

This gap obviously exists. It is said that this performance is what it should be in compliance with the specifications. It is caused by whitespace characters caused by line breaks. But this effect is obviously not what we want. The gap we want is the margin we set according to our actual needs. So how to eliminate this gap? There are three methods:

Method one: No line breaks between elements, the code is as follows:

<p class="box">  <span>111</span><span>111</span><span>111</span><span>111</span>
</p>

The effect is as follows:

Method 2: Set font-size:0 for its parent element; set the actual required font size for itself. The bad thing is that some browsers, such as chrome and opera, have minimum font settings, but chrome doesn’t seem to have this setting anymore. The code is as follows:

css:

.box{overflow-x:auto;background:#fff;white-space:nowrap;font-size:0;}
.box span{display:inline-block;width:100px;height:30px;line-height:30px;text-align:center;background:#f00;color:#fff;font-size:14px;}

Copy after login

html:

<p class="box">
    <span>111</span>
    <span>111</span>
    <span>111</span>
    <span>111</span>
</p>

Copy after login

The effect is as follows:

Method 3: Negative margin method, what needs to be paid attention to is the gap and the font size The size is related, so the gap is not a definite value.

Of the above three methods, the first two are better solutions, and the third method is not recommended. There are other solutions online, but I think the first two are better.
