In computer terms, a border can mean several things. One is a visual border in a document, sometimes a solid line, dotted or dashed line, or one made up of various objects, like flowers, baseballs, animals or virtually any other object. These borders can be used to represent the outer edge of a document or separate sections within a document from each other. Below are some other example of how borders are used on computers.

HTML borders

With HTML, there are several types of borders. For example, images that are links will contain a border around them. Using CSS or HTML, you can remove or change how these borders appear.

Table borders can also be added around the table and cells inside the table. For example, the table below is an example of a table with a border thickness of two surrounding the table.

Microsoft Word borders

In Microsoft Word, you can have a page border, which gives you a border around the page or a border around text on the page. Visit one of the links below for steps on how to create borders in Microsoft Word.

Excel border

Borders can also be added around any cells within Microsoft Excel or other spreadsheets. To change the borders of cells, select either the cells or the rows or columns containing the cells, right-click on the selected cells, and then click Format Cells. In the Format Cells window, click the Border tab. As can be seen in the picture below, the borders tab allows you to select the line type you want around the border. By default, it is a single solid line.

If you want a single border around all the cells, click "Outline." If you want a line breaking up each individually highlighted cell, click "Outline" and then "Inside" to have both types of borders. If you want to design a custom border, you can also draw each border individually by clicking on each border line you want to appear in the Border section. Finally, the border color can also be changed by changing the color from automatic to the color of your choice.

Window border

Similar to a border in a document, another type of border is one used to show the outer edge of a computer application. Each application has a border around the application window, often with either a solid color or a partially transparent border, to identify where an application window starts and ends.

Programming border

Another type of border is one that cannot be physically seen, but is set within computer programming code, to keep a mouse cursor from moving past a certain point. In an operating system, a border can keep a mouse pointer on the current computer screen. In a video game, a border can also keep a mouse cursor on the screen to help users know where their mouse cursor is located. Without it, a mouse cursor could disappear from the screen and make it difficult for a user to find it again and use the mouse.
