How to Use a CSS Filter

Building websites takes a certain amount of patience and persistence. One commonly used web programming technique is the use of CSS filters. This enables a web site programmer to get consistent behavior for their website using these embedded CSS filters.

Instructions

Difficulty: Challenging

1. Target the specific CSS or cascading style sheet filter to use for the website or page. There are many to choose from but usually trial and error is the best tool to find the CSS filter for a particular page or website.
2. Insert the CSS filter into the webpage header below the HTML header information.
3. Experiment with individual attributes of the CSS filter to get the appropriate effect. For example, the speed of the CSS filter transition can be changed by altering the transition number value in the filter.
4. Test the CSS filter with different web browsers to ensure the filter is working properly. Some filters do not work with certain types of web browsers.
5. Implement the CSS filter on all applicable web pages. It is important for a web site to maintain continuity throughout the site. Therefore, each CSS filter installed on one page may need to be spread through the entire website. Some website software has automated features the will do this for a programmer.

Tips & Warnings

• Understand that each time a new version of a web browser is introduced, CSS filters may not work on these newer versions.
