How to create a collapsible border in HTML?

We use the border-collapse attribute to create a collapsed border in HTML. border-collapse is a CSS property that sets whether the table border should collapse into a single border or be separated from its own border in HTML.

How to create a collapsible border in HTML?

Border-collapse attribute has four values: separate, collapse, initial, inherit.

Collapse with value

If collapse is passed as the value of the border-collapse property, the table's border will simply collapse to a single border. Following is the syntax for creating a collapsible border in HTML.

border-collapse: collapse;

Example 1

In the example given below, we are trying to create a folding border in HTML -

<!DOCTYPE html>
<html>
<head>
   <meta charset="UTF-8">
   <meta http-equiv="X-UA-Compatible" content="IE=edge">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <style>
      table,
      tr,
      th,
      td {
         border: 1px solid black;
         border-collapse: collapse;
      }
   </style>
</head>
<body>
   <h2 id="Tables-in-HTML">Tables in HTML</h2>
   <table style="width: 100%">
   <tr>
      <th>First Name </th>
      <th>Job role</th>
   </tr>
   <tr>
      <td>Tharun</td>
      <td>Content writer</td>
   </tr>
   <tr>
      <td>Akshaj</td>
      <td>Content writer</td>
   </tr>
   </table>
</body>
</html>

The following is the output of the above example program.

Example 2

Let's look at another example, using collapse as the value of the border-collapse property -

<!DOCTYPE html>
<html>
<head>
   <style>
      table {border-collapse: collapse; }
      table, td, th { border: 1px solid blue; }
   </style>
</head>
<body>
   <h1 id="Technologies">Technologies</h1>
   <table>
      <tr>
         <th>IDE</th>
         <th>Database</th>
      </tr>
      <tr>
         <td>NetBeans IDE</td>
         <td>MySQL</td>
      </tr>
   </table>
</body>
</html>

Separate as value

If we create a collapsed border by passing separate as the value of the border-collapse property , the individual cells will be wrapped in separate borders.

border-collapse:separate;

Example 1

In the example given below, we are trying to create a separate collapsible border in HTML.

<!DOCTYPE html>
<html>
<head>
   <meta charset="UTF-8">
   <meta http-equiv="X-UA-Compatible" content="IE=edge">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <style>
      table,tr,th,td {
         border:1px solid black;
         border-collapse:separate;
      }
   </style>
</head>
<body>
   <h2 id="Tables-in-HTML">Tables in HTML</h2>
   <table style="width: 100%">
      <tr>
         <th >First Name </th>
         <th>Job role</th>
      </tr>
      <tr>
         <td >Tharun</td>
         <td >Content writer</td>
      </tr>
      <tr>
         <td >Akshaj</td>
         <td >Content writer</td>
      </tr>
      </table>
</body>
</html>

The following is the output of the above example program.

Example 2

Let's look at another example where split is used as the value of the border-collapse property -

<!DOCTYPE html>
<html>
<head>
   <style>
      table {
         border-collapse: separate;
      }
      table,
      td,
      th {
         border: 1px solid blue;
      }
   </style>
</head>
<body>
   <h1 id="Technologies">Technologies</h1>
   <table>
   <tr>
      <th>IDE</th>
      <th>Database</th>
   </tr>
   <tr>
      <td>NetBeans IDE</td>
      <td>MySQL</td>
   </tr>
   </table>
</body>
</html>

Use initial value as value

If initial is passed as the value of the border-collapse property, it will be set to its default value, which is alone. Below is the syntax, which uses the initial properties of the border-collapse attribute in HTML.

border-collapse:initial;

Example

An example is given below, which uses the initial attribute of the border-collapse attribute in HTML.

<!DOCTYPE html>
<html>
<head>
   <meta charset="UTF-8">
   <meta http-equiv="X-UA-Compatible" content="IE=edge">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <style>
      table,tr,th,td {
         border:1px solid black;
         border-collapse:initial;
      }
   </style>
</head>
<body>
   <h2 id="Tables-in-HTML">Tables in HTML</h2>
   <table style="width: 100%">
      <tr>
         <th >First Name </th>
         <th>Job role</th>
      </tr>
      <tr>
         <td >Tharun</td>
         <td >Content writer</td>
      </tr>
      <tr>
         <td >Akshaj</td>
         <td >Content writer</td>
      </tr>
   </table>
</body>
</html>
