CSS Change Text On Hover
CSS is known for styling, but it can be used to emulate a complex programming language. For example, the pseudo-selector hover can be manipulated to replace text. This works with CSS 2.1 and up and all browsers that support the hover function.
The entire text is present on the screen. The text is broken up into parts to be hidden until required and parts that are shown by default. When a user hovers over the text, the hidden part is shown and the default text is hidden.
This tutorial uses the HTML and CSS hover function. The CSS hover function is used to show hidden text.
- Tools are required:
- Text editor.
- HTML.
- CSS.
- Browser to view output.
Optional Download and install suitable text editor
Any text editor with regular expression support will work. To select a reviewed lightweight programming editor read the Ojambo.com Lightweight Programming Editors.

Conclusion:
CSS is not just for styling content. With some imagination, the hover function can be used to emulate changing text. It works by diving text is two parts, one is the default and the other is hidden. The hidden text will be shown during the hover event.
- Recommendations:
- Use CSS to eliminate the need to run server-side code.
- Use CSS to eliminate the need to run JavaScript code.
- Do not assume users want or have enable JavaScript.
