What Is Border Collapse Css

CSS Programming

Border-collapse in CSS is a property that controls how the borders of adjacent table cells interact with each other. It determines whether the borders should collapse into a single border or should be separated as individual borders.

Personally, I find the border-collapse property to be quite useful when working with table layouts. It provides a way to control the appearance of table borders and helps to achieve a cleaner and more consistent look.

When the border-collapse property is set to “collapse”, the borders of adjacent cells will collapse into a single border. This means that the cell spacing between the cells will be shared and the table will have a more compact appearance. On the other hand, when the property is set to “separate”, each cell will have its own border and the cell spacing will be independent.

Let’s take a closer look at how the border-collapse property works:


The syntax for using the border-collapse property is quite straightforward. You simply include it in the CSS rule for the table element and set its value to either “collapse” or “separate”. Here’s an example:

table {
border-collapse: collapse;


The border-collapse property has two possible values:

  • collapse: This value collapses the borders of adjacent cells into a single border. This is the default value.
  • separate: This value separates the borders of adjacent cells and gives each cell its own border.

It’s important to note that the border-collapse property only applies to table elements and their immediate children. It does not affect other elements on the page.

Browser Support:

The border-collapse property is supported by all major browsers including Chrome, Firefox, Safari, and Edge. However, it’s always a good practice to check for browser compatibility before using any CSS property.

In conclusion, the border-collapse property is a useful tool for controlling the appearance of table borders. Whether you want a more compact and unified look or prefer separate borders for each cell, this property gives you the flexibility to achieve the desired result. So next time you’re working with tables in your web design projects, don’t forget to consider the border-collapse property!


The border-collapse property in CSS allows you to control how the borders of adjacent table cells interact with each other. By setting the value to “collapse” or “separate”, you can achieve a more compact or separate border appearance. This property is supported by all major browsers and is a valuable tool for creating clean and consistent table layouts.
