Hi, my name is Dan. In this video we're gonna look at compound selectors. Now we've looked at a little earlier compound selectors. We're gonna cover it again because uh,  it's important in this case  because, uh, at the moment these buttons here are using some  styling that's coming from Bootstrap, which is kind  of a light gray, um, which is the link. And the hover is a dark gray, so I need to change it. Now you might be asking why,  'cause we've done the links earlier on.

Remember down the bottom here, we went  and changed all the links to have this white  and we changed the rollovers. Why haven't these come along for the ride? And the reason is, is  because Bootstrap has its own specific. So if there was no styling coming from Bootstrap,  they would be perfect with their white a link. But because Bootstrap specifically said be light gray  and then a dark rollover gray,  it's taking control of that styling. So we're gonna have to take it back again by overriding it.

So what we need to do is we need to go through  and create a compound selector. So let's do that. 'cause what I want  to do is I'm gonna click on here  and there is an a link here, remember? And there's a list item and there's all this junk. Okay? That goes in before it.

So what I can do is I can do a specific compound selector. So if I hit selector, this is a compound selector. It's gone through and it's styling everything. Every link, which is the A that is inside of a list, that is  inside of a class called uh, nav bar, right? Which is inside of a class called Nav Bar Nav, which is  inside another class called nav. So it says, if these all are true, apply this style.

Okay? Now this is a little messy. It's quite a lot of detail in here. What you could do is you could tidy  it up by just saying this. If there is an active link that is inside a list item  that is inside this whole overriding nav,  this whole thing here is the nav class. That would work just as well.

Okay? It's up to you. This looks cleaner and tidier and more impressive. And this bit here will work, but it's quite specific  and a little bit ugly. So let's make it look pretty by tying it down. 'cause it is still true.

There is an active link which is  inside a list item, which is inside of the nav. The reason I don't, 'cause I could tidy it down even closer. I could do just this link that is inside the nav. Problem is, is that there is, over here there's a link. Okay? Remember we added a link where it says,  if I click my logo, it's gonna jump to the homepage.

I don't want that to be affected by this list. So I want it to be a little bit more specific. Okay? So the link that's inside the list item,  which are these two guys here, right? So what we are gonna do is, um,  what we also wanna do is I want it to be slightly different. Remember we can put in our, remember what those are called.

That's right. Our pseudo classes. Okay. 'cause I want to not just style the link. I wanna do the link and the hover. Great.

So to do it, I'm gonna go down to my type. Now I'm gonna change the color of it. I'm gonna switch it out to white  and hey Presto, we've got our links being white. Cool. So compound selectors can be a little confusing. Um, we've done it  A couple of times now.

And the other thing to note is  that sometimes when you're working with Bootstrap, you need  to go and find, there'll be a bit of CSS that's counter  or overriding what you are trying to do with some  of your baseline things like we did with our styling,  our basic links for the whole website. Alright, that's it for this video. We are now gonna do our backup. Okay? A file. We're gonna do a save all.

And now we're gonna go out to our desktop  and I'm gonna copy it. I'm gonna go into diss old and I'm gonna put it in here. I'm gonna rename it, call this one backup,  and we're gonna put the following date. It's not the following date, so I am going to just give it  the year of the month,  and I'm gonna put O four B in the day. Great. See you in the next video.
