This site uses the "Sinatra" free WordPress theme as its base. Sinatra includes a single "Hero Header" the row of 3 animated featured posts on the home page which changes background images as you mouse over post titles within it.
I wanted this to be multi-row, a grid instead of just one row. The code natively contained an option to include up to 12 featured posts, which could easily be made to wrap around to new rows, but the problem was, the background of the entire section containing all rows changed when you moused over a post, not just the single row, and I wanted not just a row-by-row background, but I wanted potentially unlimited rows.
I moved the code that generates the rows into a function, and then called it repeatedly, once for each row I want. At some point I may make it automatically add as many rows as are required to display all posts, but as of this writing, every time I add one more post than there is room for, I edit the bottom of this file to add another row.
Furthermore, originally, the theme CSS was really sloppy:
1.) There's a lot of identifying things by element, such as anchor or div tags, which the CSS then had to look up the ancestry of to see which formatting applied (as in rules similar to, "#page .hero-row .hero-slider
a {blah-blah:blah}", which is horribly inefficient compared to just giving things a class.
2.) All the changing images were done using CSS background images on <div> elements, making them hard to lazy-load and killing page performance.
3.) Plus there were a lot of animations on non-compositor-only attributes, making Google PageSpeed complain.So a lot of CSS got rewritten. I don't mind telling you: it took a while. There are still a lot of inefficiencies, like divs directly nested as the only child of other divs, that can be cleaned up. Unfortunately that's going to take a while as a lot of things are done with flexboxes, which makes refactoring all the formatting a lot tougher. So for right now I'm leaving that alone, but it's on my "future plans" list.

I'm proud to say that as of this writing (July 2, 2024) my great, big, overcomplicated (over 5000 elements) animated home page gets a 99 out of 1000 performance score on Google PageSpeed. See for yourself: Pagespeed Report
