What is Luma?
The most straightforward and obvious comparison is determining the difference between Luma and Hyvä. But we must first understand what Luma is?
Luma is an HTML, CSS, and Javascript package shipped with the Magento core. Every Adobe Commerce site has Luma pre-installed.
Luma’s performance isn’t awful but has a reasonably poor developer experience. This leads to bloat, which hurts site speed even more. We have even seen developers copy the final compiled stylesheet code and make modifications to this (effectively doubling the downloaded stylesheet file code).
Definitions:
Javascript: this is the software development language that enables user interaction. Javascript allows you to click a button with a success message subsequently appearing.
Stylesheet/CSS: stylesheets make the page look pretty. Otherwise, you’d see a white background, oddly-sized images, and Times New Roman font. Very ugly.
HTML: this language provides the overall structure of a website.
