wordpressminification-734Minification is a term used to describe the removing of unnecessary characters from code without changing it’s functionality. It’s primary use is for shrinking the overall size of the file it compresses. Minification is used on web languages like HTML, CSS, PHP and Javascript. To minify a page or script can greatly reduce the size of the overall file. This reduces how long it takes to load.

Why We Need Minification

When Coders and Programmers are working on their code it often times is much easier to read for humans with spaces and comments about sections of code. Computers do not need any of these spaces or comments and therefore can process the data much quicker without them.

Minification Plugins

How Minification Works

For WordPress users, there are plugins that provide a function that strips out all of the unneeded spaces. Essentially, all the work is done behind the scenes and takes little time to implement.

Warnings About Minification

Like any pre-built functionality, integration into every site is different. You should not expect your code to be interpreted 100% accurately upon installation. Heavily customized WordPress templates with lots of plugins, for example, may inhibit the minify plugin from working. In some cases we have scene CSS and Javascript files break and become unusable once minified. These problems can be fixed and they do not cause permanent damage, it will take some time to find errors that need to be fixed.
