CSS border-collapse Property

CSS border-collapse property specifies whether the two borders of a table cell should collapse into a single border table cell or not.

Notice the difference between the two tables:

CSS border-collapse property

In the above image, the first table has its border-collapse property set to its default value separate. Therefore, two borders appear around each cell. While the second table has its border-collapse property set to collapse. Therefore, the two borders in the second table collapsed into one and each table cell has only a single border around it.

Try out the example below to see how it works:


  border-collapse: separate; /* Default Value */
  border-collapse: collapse;
