Styling our Angular app

Now that we've got our basic application structure set up and started displaying something useful, let's switch gears and spend an article looking at how Angular handles styling of applications.

Prerequisites:	Familiarity with the core HTML, CSS, and JavaScript languages, knowledge of the terminal/command line.
Objective:	To learn how to style an Angular app.

Adding some style to Angular

The Angular CLI generates two types of style files:

Component styles: The Angular CLI gives each component its own file for styles. The styles in this file apply only to its component.
styles.css: In the src directory, the styles in this file apply to your entire application unless you specify styles at the component level.

Depending on whether you are using a CSS preprocessor, the extension on your CSS files can vary. Angular supports plain CSS, SCSS, Sass, Less, and Stylus.

In src/styles.css, paste the following styles:

css

body {
  font-family: Helvetica, Arial, sans-serif;
}

.btn-wrapper {
  /* flexbox */
  display: flex;
  flex-wrap: nowrap;
  justify-content: space-between;
}

.btn {
  color: #000;
  background-color: #fff;
  border: 2px solid #cecece;
  padding: 0.35rem 1rem 0.25rem 1rem;
  font-size: 1rem;
}

.btn:hover {
  background-color: #ecf2fd;
}

.btn:active {
  background-color: #d1e0fe;
}

.btn:focus {
  outline: none;
  border: black solid 2px;
}

.btn-primary {
  color: #fff;
  background-color: #000;
  width: 100%;
  padding: 0.75rem;
  font-size: 1.3rem;
  border: black solid 2px;
  margin: 1rem 0;
}

.btn-primary:hover {
  background-color: #444242;
}

.btn-primary:focus {
  color: #000;
  outline: none;
  border: #000 solid 2px;
  background-color: #d7ecff;
}

.btn-primary:active {
  background-color: #212020;
}

The CSS in src/styles.css apply to the entire application, however, these styles don't affect everything on the page. The next step is to add styles that apply specifically to the AppComponent.

In app.component.css, add the following styles:

css

.main {
  max-width: 500px;
  width: 85%;
  margin: 2rem auto;
  padding: 1rem;
  text-align: center;
  box-shadow: 0 2px 4px 0 rgba(0, 0, 0, 0.2), 0 2.5rem 5rem 0 rgba(0, 0, 0, 0.1);
}

@media screen and (min-width: 600px) {
  .main {
    width: 70%;
  }
}

label {
  font-size: 1.5rem;
  font-weight: bold;
  display: block;
  padding-bottom: 1rem;
}

.lg-text-input {
  width: 100%;
  padding: 1rem;
  border: 2px solid #000;
  display: block;
  box-sizing: border-box;
  font-size: 1rem;
}

.btn-wrapper {
  margin-bottom: 2rem;
}

.btn-menu {
  flex-basis: 32%;
}

.active {
  color: green;
}

ul {
  padding-inline-start: 0;
}

ul li {
  list-style: none;
}

The last step is to revisit your browser and look at how the styling has updated. Things now make a bit more sense.

Now that our brief tour of styling in Angular is done with, let's return to creating our app functionality. In the next article we will create a proper component for to-do items, and make it so that you can check, edit, and delete to-do items.
