The group that decides how CSS works has agreed to a proposal that lets developers select classes by their first few characters, using a wildcard like .prefix-*. CSS is the language that controls how a website looks. A class is just a label attached to part of a page so it can be styled.
Here is why this is a developer story and not a business story.
Sites often end up with families of labels that share a beginning: button-primary, button-small, button-ghost, and so on. Right now, styling all of them at once takes either repetition or a workaround. This change would let one line of code catch the whole family. It is a convenience for the person writing the code. It does not change how your site behaves, how fast it loads, how it ranks, or how it looks to a customer.
It is also further away than the word "resolved" suggests. Agreement on a proposal is the start of a long process, not the end of one. Browsers still have to build it, ship it, and reach enough of your visitors for anyone to use it safely on a live site. Nothing about your website is now out of date, unsupported, or in need of attention because of this.
So why does a story like this get attention at all? Because the web design world talks constantly about its own tools, and small changes to CSS get written up the way small changes to a trade's equipment get discussed among tradespeople. That conversation is genuinely useful to the people doing the work. It just does not translate into anything you need to act on. Be a little wary of anyone who uses news like this to suggest your site needs rebuilding.
What to do: nothing. Do not ask for it, do not budget for it, do not worry that your site is missing it.
If you want one thing to take from this, it is a general habit rather than a specific action. When someone tells you a web change means your site needs work, ask them a plain question: what does a customer see or experience differently? If the honest answer is nothing, it can wait.
