Optimizing HTML, CSS, and JS files through minification

During my research on various minification techniques used by different websites, I noticed that most sites employ JS minification, concatenation, and bundling all JS files into one, which I believe is a good practice.

However, CSS and HTML minification seems to be limited to removing extra spaces and comments in most cases.

I was intrigued to find out that Google utilizes unique minification techniques where they modify selector names in both the HTML and CSS files for better optimization.

I am curious to learn more about this specific minification architecture employed by Google. :-)

Answer №1

Enhanced CSS compression

Currently, I have integrated the CSSO minimizer tool with gulp and gulp-csso for advanced CSS minification.

CSSO (CSS Optimizer) stands out from other CSS minimizers as it not only reduces file size through typical minification techniques but also conducts structural optimization of CSS files for further reduction.

While it works effectively, the optimizations provided by CSSO may not yield substantial gains in file size reduction.

I suggest exploring PageSpeed Tools to evaluate your asset optimization needs if you haven't already. This tool offers insights into the type of optimizations required for improved performance.
