So this evening I've been working on a way to make it easier to add filters to blog pages without JS. This is mainly an alternative to isotope, commonly used in icon, media, downloads, and portfolio pages. CSS only solutions, especially like this, can be intimidating to look at even if you're not new to CSS.
I'm hoping this will take care of the bulk of the work/the more complicated parts so that you can make more complex custom pages without the user having to wait for permission to use JS.
Here's a simple example with just display: none added to the CSS
And on my preview page, I've used the same code and added multiple filter groups and some CSS animations.
If you are familiar enough with HTML and CSS, you can try out what I currently have, but keep in mind you will still need to write most of the HTML and CSS yourself. I want to make a more detailed guide so that it's easier to use soon!
