Quick overview of how the Bootstrap Grid Layout works in VS Code

Hello there. Welcome to the overview for the bootstrap layout system. Okay. Also known as the grid system or maybe the structure it is the boxes that make up our website and the cool thing about it is we're going to write just a tiny bit of code, a container with some div tags in it. Basically. No CSS at all. Just a background color and look what we're able to do. Okay. We've got boxes that are just sizes that are centered. We haven't done any of this. Media queries are all in there already. I'm going to try and amaze you with bootstrap and it's amazing layout system. Let's get started. Alright, first up we're going to close down our index page. We're gonna save him for like our main website that will build kind of towards the end of this kind of section. We're going to create a couple of throwaway files so we're gonna right click new file and we're going to say this one is overview and this one is going to be now grid is a really clear word of what we're doing structures. Another good...

word. Bootstrap refers to it as the layout. So we're going to call it that. It's a layout dot html Alright, so let's add our stuff. Okay, exclamation mark. Make sure that in here we add our comma shrink to fit. I know there's a couple of other parts, we want, we want where we want it, we want this. Okay, the CSS pop it in just under the title and we don't need the javascript for the moment because we're not using it. You can use all of the amazing media queries and grid system without touching any of the javascript. It's only if you want the kind of fancy thumbnail pop up the things. Cool. So let's first of all down here in our body. Put in a container. Now let's put in dr container. Okay. It's a nice class. Let's add some styling to it now because we're doing a pretty throwaway document. I'm not gonna bother putting the style in its own sheet. I'm just going to put it up here in the head. Okay? It's the same thing, but not a separate sheet. And I'm going to say, let's give the container the container, I think give it the full stub container is going to be what we gonna do? Just a background color. So background cole is going to be random. Today's one is thistle that's not good enough to see on screen. You need something darker, please. Random spinning to activate it again. Go back to start typing in color that should prove fill it in. Ok? You got magenta, lovely pink color. Let's have a little look in the browser. There. It is there. That is not it because it's my index page. Let's turn it off. Turn it back on again. Nothing happens. I need to put something in the container. Okay, so over here. Let's put it in our H1. Okay. H one. Put something in there and you're amazed. What are you amazed about? You were like this is the container. Ah but it's also a width. Okay. It has a width on it. We didn't give it a width and it also has centered. It's centered. Okay. And the H. One has been kind of styled, You've already already kind of work that out. So that's a real big benefit of using Bootstrap you like even if you just use it for this grid layout system, that's just brilliant. The other cool thing is watch what happens when I shrink it down? Let's go to right click inspect. Let's switch it to make sure this is on the device, was it called device toggle tuba. Turn that on and make sure it's set to responsive at the top because we want to go like this watch, I've kind of given it away but large it adjusts already for lots of media queries. Okay. You can see them along the top there. They're already ready to go. And even mobile, you can see there's some padding already in inside of the container. That's Bootstrap saying nobody ever wants their text jammed against the side. And you're like, that's true. Thank you. Bootstrap, the other thing it says is like let's put the container right to the edges on mobile devices. But out here we'll give you a little bit of room around the outside so you can do some kind of proper design rather than trying to stretch it all out. Okay, there's just some nice things that Bootstrap does now to use? Bootstrap. You really need to make sure that you are using the right language and that's what we're going to do in this kind of section is get you used to using the right language and I've tried to prep you for the rest of the course. That's why we call it container earlier on and not rapper. Like some people call it because in here let's go to our layout. Okay. That we're going to use the documentation more and more but under layout it says you can see a container is the word they use for this thing. Okay, fluid containers will look at later on. So we're gonna go back and forth through the documentations just to get you used to it. Okay. Next thing I want to show you is what you can do inside of here. So let's get rid of this H inside of the container. Let's put in a dot ro. Okay. Rose, what they use as the kind of wrapper containers that go around. Anything that's not the container container has a really specific use gets centered every time. Whereas this is like a container. Okay. But gets used inside of the main container. Manos spelling that wrong. Let's just do it and understand it. So you never have a row by itself. It always has things inside of it. And those things inside of it are normally always called cole's okay for columns, rows and columns. How many do we want? We'll have three. Okay, remember it is shift option down arrow on my mac and that's all to shift down arrow on a Pc. So that's three goals. Let's type some stuff inside of it. This one is going to be one. This one is going to be too And you guessed it three. Now, what is fancy? We've got to make sure Rose okay. Are the rapper and these columns are the things that go inside of it. Let's save it. Let's have a little look. And in our document here, can you see I've got rid of the H one. Okay. There's a container which has still got my magenta, but you see what it did. It separated these into, well, it put them into kind of a nice little group. So what it's doing here. Remember before every parent rapper, we had to add display flex, bootstrap by itself without asking assumes if you use row inside of row. Okay, All the Children are gonna flex. That's something handy, Right? That's just another thing that's cut down and you'll notice that our style sheet At the moment, just as container and it doesn't even need this container background. You can see how far we've got without having touched CCS. This background here is just so you can see it in the middle now. That was cool. Okay, so separating them to three even groups. They have other things that make it really cool. Let's say we want the first box to be eight across. So we've got the same 12 column grid. Okay, you can break your website into 12 little groups. Okay. Or 12 columns. So I could say hyphen eight under this coal. So coal hyphenate. Okay, let's have a look. You see it updated. That is eight. And these guys, because they don't have a number, they assume they fit the rest of it. So 8 19. So these are two rows and 11, 12 here. Cool. Hey, we didn't have to do anything, remember before we had to kind of percentages and stuff like that. It was hard going and you're like, this is amazing. Can it get any better? It does. Okay, so let's not use just a plain old eight. Okay, we can use a bit more media query specific. What do I mean by that? I mean that in let's look in our preview here. Okay. We looked at the media craze before. Okay, so these are all in here by default. So what we can do is easily say this from here outwards. It's called Excel. Okay, this here is called large and this little space here, this little space here is called medium. This one's called small and anywhere below, I think it was it 56576. Okay. Is considered extra small. So we can use that language to kind of identify this because at the moment they do the same thing on all of them. Right. Nothing really changes. So let's say that I wanna put my multiple personalities just do it. So we'll do this first one here. We'll do hyphen algae. Okay. And we'll say let's make it 10. Okay. So that first column is going to try and occupy 10 columns. It's nice and simple. But you have to use that syntax LGS for large. And these other two fellas wrong shortcut command and hold down the option key and use the down arrow to do multiple curses on a pc. It's control and halt and down arrow. So in this case I'm going to say large is going to fill these other two. No, it has to feel one. Well that's the equal 12. There's chicken in the browser and you can see here. So I'm at small at the moment. Okay. And there's this one here. No, there's medium and large. Hey, look at that. It goes 11 note 10 and then 12. So I can target more than one. Okay. So at large is doing that. But I would like to let's say putting in multiple cases on my Mac. I'm holding down the option key and clicking Pc is old. Okay. And I'm going to say on this one. So there's just a space you have to use lower case. And we're going to say the call for, let's say the small one. K. Is going to be six. Okay. And then these two are going to be three and three All Equal 12. Let's have a little look up here. It's still doing my 1011 now down here, you can see it there, it goes six and then three and three and you can see by default just Bootstrap really wants it to stack on top of each other when it's down at extra small and you'll notice that something we tried to do lots when we were building our website, everything was kind of stacked horizontally until it got to here and we stacked on top of each other. You can override that. Okay. The weird thing about it and I guess a good thing to mention is that there's no X. S. As a never put an X. S. Here. Okay, excess even. Okay. It assumes if you don't write anything you mean? So if I did cole and this is going to be four, okay. It assumes X. S. It's what's called mobile first. Okay. We built our last website saying we assume everything is desktop unless told otherwise. Bootstrap is built the other way around. It assumes everything is mobile. So if I just put coal without any sort of indication, it assumes a mobile phone. So here we go there. 344, 4. Cool, how was that? There was a brief introduction. Okay, there's lots more to it but I hope you can see the power of it, like, especially because our styling is like this and the cool thing about it is that everyone's got the same styling. So if you take on somebody else's theme or somebody else's CMS or somebody else's web site and it's built on bootstrap, you'd be like, yes. Because you know what these things do and they're written the same way. Plus a lot of the fiddly stuff is done like this container. Okay. The media queries are already in there. They do nice things by default. You can override them all, but for the most part, they do exactly what you wanted to do. All right. So that is the quick overview for the grid. We're going to do more, but I feel like we should go through all three parts before we get into like the nuts and bolts are building our site. Alright, I'll see you in the next video
