CSS or Cascading Style Sheets is a style sheet language used for describing the presentation of a document written in HTML or XML. It is used to style web pages and user interfaces written in HTML and XHTML. CSS has a wide range of properties that can be used to style web pages. One such property is border-collapse.
Border-collapse is a CSS property that is used to specify whether the borders of table cells should be collapsed into a single border or separated as individual borders. It is used to control the spacing and appearance of table borders. The border-collapse property is used in conjunction with the border-spacing property to control the spacing between table cells.
The border-collapse property has two possible values: collapse and separate. The default value is separate. When the value is set to separate, each cell has its own border. When the value is set to collapse, the borders of adjacent cells are merged into a single border. This can create a cleaner and more streamlined appearance for tables.
Here is an example of how to use the border-collapse property:
table {
border-collapse: collapse;
}
In this example, the border-collapse property is applied to a table element. The value of the property is set to collapse, which means that the borders of adjacent cells will be merged into a single border.
Here is another example that shows how to use the border-collapse property in conjunction with the border-spacing property:
table {
border-collapse: separate;
border-spacing: 10px;
}
In this example, the border-collapse property is set to separate, which means that each cell will have its own border. The border-spacing property is set to 10px, which means that there will be a 10-pixel gap between adjacent cells.
The border-collapse property can be used to create a variety of different table styles. For example, it can be used to create tables with no borders, tables with merged borders, or tables with individual borders for each cell.
Here is an example of how to create a table with no borders:
table {
border-collapse: collapse;
border: none;
}
In this example, the border-collapse property is set to collapse, which means that the borders of adjacent cells will be merged into a single border. The border property is set to none, which means that there will be no border around the table.
Overall, the border-collapse property is a useful CSS property that can be used to control the appearance of table borders. It can be used to create a variety of different table styles, and can be used in conjunction with other CSS properties to create complex table layouts.
