I’m looking to add basic HTML and CSS (modal pop ups, banners, sliders, buttons etc.) to my homepage. Im fairly new to Magento and hoping someone can elaborate on the best way to accomplish this. I’m not looking to install plugins or page builders, but rather upload my code via FTP and PHPstorm. From my understanding I’d have to create a child theme, modify/create new HTML, then add blocks referencing said HTML/CSS in order to have it show on the front end. Am I on the right track here?
