Cascading Style sheets, or CSS, is a language created for the presentation of content on the web using different styles and fonts. Considered one of the “cornerstone technologies” of the web, CSS is typically stored in external stylesheets, or .css files, but it can also be integrated directly into HTML documents. The use of CSS makes websites easily accessible because it separates the web’s contents from its presentation. It also reduces the complexity of the website because it keeps information about fonts and colors separate from the main content. However, if used excessively, CSS can fast become a stumbling block for your website’s performance because it the length and detail of coding that goes into a CSS file can cause excessive network traffic that provides no substantial benefit to you or your website surfer. In such cases, a website’s CSS can be minified. Minification is the process of minimizing code and markup in your web pages and script files. It’s one of the main methods used to reduce load times and bandwidth usage on websites. Minification dramatically improves site speed and accessibility, directly translating into a better user experience. It’s also beneficial to users accessing your website through a limited data plan and who would like to save on their bandwidth usage while surfing the web.
When you minify a website’s CSS, you reduce the file size by up to 30-50%, making it easier and more convenient for the browser to process and render it, thus saving up lag time and loading browser pages faster and with more accuracy.
When a CSS file is minified, all the unnecessary characters are removed which include paces, commas, tabs, new lines etc. This considerably reduces the size of the file.
Minification is also responsible for improving site speed and accessibility which leads to a better user experience overall and can encourage web surfers to return to your website. Moreover, it also provides convenience to users who are accessing your website through a limited data plan and who would like to save on their bandwidth usage while surfing the web.
While using CSS for a website developing is one of the most useful tools in today’s time, using it just a little more sensibly through minification can greatly affect the performance of your website which can have an overall greater impact on the image of your brand.
