CSSWizardry, aka Harry Roberts, who is (was?) big on BEMCSS and ITCSS, and the author of <a href="https://cssguidelin.es/" rel="nofollow">https://cssguidelin.es/</a>.<p>He's helped me really understand how to properly take care of CSS and make sense of them.<p>Recommend reading his blog and that guidelines site to get a grip on CSS if you've struggled with it.
