>> So you're ready for one of my all time favorite tricks. This is where this comes in super handy so again let's say that you live in the world of content management systems. That's my deep background I come from in Joomla, originally I do work with WordPress and so forth.

[00:00:15] So, one of the things that happens is your styling and maybe for accessibility purposes, you need to flag every time somebody links to a PDF. Now exactly how likely it is that your client is typing away. They're in their little editing window. That they're gonna stick a parenthesis PDF after every link that has a PDF on it, right.

[00:00:37] Yeah, zero it's just never gonna happen. Wouldn't it be great if we could program that? We can, using the arbitrary selectors. So, with that hint in mind, how about I give you like three minutes. Think about how could you, so using the attribute selectors, I don't tell you which one, you can pick select all links to PDFs.

[00:01:16] On the page and put a PDF in parentheses after it. Okay, take three minutes and see if you can write the selector.
