As you add more tools and content to your site, the number of files will expand, leading to slower loading times. Speed matters<\/a> on the internet, so a slow-loading site can be a big problem.<\/p>\n\n\n\n

One way you can combat this problem is through minification. This is the process of compressing certain files (such as CSS, JavaScript, and HTML files) to shrink their size without impacting their functionality. The best part is you don\u2019t even need any coding know-how to minify these files!<\/p>\n\n\n\n

What is Minification?<\/b><\/h2>\n\n\n\n

Every second counts on the internet. As websites become more optimized, many people have been primed to expect fast loading times. In fact, almost half of all internet users expect sites to load in two seconds<\/a> or less.<\/p>\n\n\n\n

When a single-second delay can result in a seven percent reduction in conversions, being stuck with a slow site can be a death sentence. Fortunately, there are remedies to help you speed up your site, including minification.<\/p>\n\n\n\n

This refers to the process of compressing Cascading Style Sheets (CSS), JavaScript, and HTML code without affecting the functionality of these files. You may not realize it, but many of the files that keep your site running can also be slowing it down.<\/p>\n\n\n\n

This minification process may sound overly technical on the surface, but it\u2019s very straightforward. It simply involves removing unnecessary characters from the code.<\/p>\n\n\n\n

Let\u2019s look at an example. Here\u2019s what a normal CSS snippet might look like:<\/p>\n\n\n\n

#bluetext {\nfont-size: 2em;\ncolor: blue;\n}<\/pre>\n\n\n\n
#redtext {\nfont-size: 1em;\ncolor: red;\n}<\/pre>\n\n\n\n
If you were to minify this code, the result might end up looking like this:<\/p>\n\n\n\n
#bluetext{font-size:2em;color:blue;}#redtext{font-size:1em;color:red;}<\/pre>\n\n\n\n
All of the required information is still there, but the line breaks, spaces, and some other characters have been removed. These elements are not necessary for a computer to understand the code and only exist to make it more readable to humans.<\/p>\n\n\n\n
It may not seem like this minor change would have a big effect, but think about how many lines of code you have running under your site\u2019s hood. Minification can significantly cut down the size of each file, which will, in turn, make your site load faster. This is especially true if your site contains a large number of files, scripts, and plugins.<\/p>\n\n\n\n
We\u2019re now going to look at two methods you can use to minify code, both manually and with a dedicated plugin.<\/p>\n\n\n\n
