It'll have some texts in the middle of it, and the image will take a certain size of the sort of height of the browser and then will have another section with some text. We're going to create something that looks like this, an image that is a hero type of image. All right, so let's take time to figure this out. All these classes will lock in at a certain point, and then when they reach their particular sort of break point, they'll lock into a hundred percent of the width of the container and you can see that happening with all these classes as I make my window smaller. You could see that when I go to a different size, it's going to lock or it's going to jump a little bit and lock into a new size. I added some additional styles here to make it the full width of the browser here, but you could see that in the next section, this container right here, I've made that container fit the current Grid, and I'm going to take this out of full screen mode so you can see that when I make it a different size, it locks into the different viewport positions. So we'll take a look at this and you can see that for this main image, usually known as the hero image, I've just added that image here and I haven't placed it inside a container. If you want something to go all the way to the edge of the screen, you don't use a container. Now container fluid is always going to be a hundred percent of the width of the container or the viewport and it'll still have a little bit of room on the sides. And it continues to do that for all these different sizes. ![]() Now, if you add any of these size attributes here, then the Grid will remain at a hundred percent of the width of the container plus that little bit of extra room on the sides until it reaches a certain break point, and then it would lock in to that size. And so on and so forth when the window or the width of the browser, when the width of the viewport reaches 992, it locks to 960, et cetera, et cetera for all of these different measurements. When the width reaches 768 pixels, the content locks into a width of 720 pixels, and it doesn't grow any larger than that. Whenever your viewport reaches 576 pixels or greater, the content will lock into a width of 540 pixels, in the case of this regular container. You saw that in the example, there's a little bit of space around the edges when you use any of the container classes. And essentially what happens is that the regular container class will be a hundred percent of the width of the container minus a little bit of space around the edges. Okay, let's review the container metrics. You could see that we have the call classes three times in here with some text, and that is what displays the elements. The rows essentially prepare the columns for display and the columns would hold the contents. If I created another row, and if I repeated these three items, it would be three items, but it would set up a new Grid. So the row is what allows these three elements to appear. Going to take a look at what I've done here, which is just create three columns, and to do that, I created a div with a class of container that makes it align to the main Grid system. There's a lot of different options to these different parts, but this is the sort of most minimal Grid that you can create. And inside those rows, you create additional columns. ![]() You would create a div with a class of container and inside that you would create one or more rows. Now there's also classes that relate to both Flexbox and Grid, and you can combine these classes with the Grid classes, but Grid is the main layout structure. Now each one of those classes will allow you to set up the Grid system. In addition to that, there are also two classes called rows, as well as columns. We discussed the container class at the top of this course. The Grid system has three main components. ![]() I’ll be going over all the responsive design requirements as well as how to add responsive breakpoints and using grid naming etc.- Bootstrap's Grid is designed around a responsive 12 column system implemented through Flexbox.
