2.5 Global Styling

Hi folks. In this lesson we're going to see how we can add global styling for our application as opposed to the highly specific component styling that we looked at in the last lesson. To add application-level styling, the CLI has already added a file to the root of our application called styles.scss. Any styles that we add to this file will be global and will not be scoped to a particular component. I like to keep this file free from any actual CSS, and use it just for imports. So we currently have a folder in the app folder called assets. At the moment, it only contains this .gitkeep file. And that just makes sure that the empty folder gets included by Git. So we can go ahead and delete this file now. And let's add a new folder inside this assets folder called styles. Inside this new folder, let's add a new file. We'll call it _variables.scss. So inside this new file, let's add some Sass variables. So we've added four variables here. Three different colors, which are used throughout the application, and the last is the font family. So next let's add a folder in the assets folder called fonts. I've got some font files ready on my desktop, so I'm gonna drag these into this new fonts folder that I've just created. So these are all open source and free fonts. You can download them all from Google Fonts. So now let's add another Sass file to the styles folder, this one called _fonts.scss. Inside this file, we can add some CSS for the custom font that we're going to be using. So note that the paths to the font files are relative to the root src folder, not the styles folder that this file currently resides in, because we're going to be importing this file into other files. So let's add one final new file now to the styles folder. This one is called _app.scss and we'll use this for some global styling. So this file uses some of the variables that we've defined in the other Sass files that we've added. So now we can import all of these files. We need to do this in the styles.scss file in the root of the application. Let's just make sure everything's saved. So let's get rid of this generic comment. So let's go back to the browser now. And we can see that the appearance of the page has changed again, specifically the font that we're using for the title of the application. And let's take a look at the head of the page once again. And again, we've got two style elements here in the head. And when we open up the first one now, we see all of the global styling that we added and imported into the style.scss file. So in this lesson, we saw that to add global styling for our application, we need to add styles to the style.scss file in the root of the src folder. We also saw that we can use imports in this file in order to help keep our Sass nice and modular. Thanks for watching.
