What does collapse mean in css?
The border-collapse property in CSS is used to set whether table borders are merged. It has three values. Among them, separate means separating borders, collapse means merging borders, and inherit means inheriting attributes from the parent.
When making a table, we can use the border-collapse attribute to merge the two borders into one, making the border effect more beautiful. Beautiful.
The border-collapse property sets whether the table's borders are collapsed into a single border, or displayed separately as in standard HTML.
The example is as follows:
<html>
<head>
<style type="text/css">
table{
border-collapse:collapse;
}
table, td, th{
border:1px solid black;
}
</style>
</head>
<body>
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
</tr>
<tr>
<td>Bill</td>
<td>Gates</td>
</tr>
<tr>
<td>Steven</td>
<td>Jobs</td>
</tr>
</table>
