Leveraging semantic HTML along with Angular Material and Flex Layout for optimized web design

As I dive into learning Angular (along with Angular Material and Flex-Layout), one aspect that seems a bit murky to me is how to maintain semantic HTML while utilizing these frameworks. Most examples I come across focus on specific Material / Flex-Layout tags without mentioning basic elements like header, main, etc.

For my initial simple page build, I'm contemplating the following structure, but unsure if it's the right approach:

<body>
   <header><!-- header with other mat elements... --></header>
   <mat-sidenav-container>
      <nav>
         <mat-sidenav></mat-sidenav>
      </nav>
      <main>
         <mat-sidenav-content></mat-sidenav-content>
      </main>
   </mat-sidenav-container>
   <footer></footer>
</body>

My specific questions are: 1) Are header, nav, main and footer correctly positioned? 2) Are they still necessary when using these material elements?

Thank you!

Answer №1

When working with HTML5, tags are organized into different content models. The main goal of using semantic HTML5 is to structure the entire page in a meaningful manner. For a comparison between HTML4 and HTML5, check out this resource. However, when discussing semantic HTML5 within an Angular Component context, it becomes irrelevant. In Angular, components can be given semantic meaning simply by naming them, and the HTML files are designed with isolation and reusability in mind.

Now onto your queries:

  1. It is recommended to create components that have semantic significance:
<body>
   <header>header with other mat elements...</header>  <---- this will become header-component
   <mat-sidenav-container> <--- this will become main-component
      <nav>
         <mat-sidenav></mat-sidenav>
      </nav>
      <main>
         <mat-sidenav-content></mat-sidenav-content>
      </main>
   </mat-sidenav-container>
   <footer></footer> <--- this will become footer-component
</body>

Implementing this approach would result in the following structure:

index.html

<body>
   <header-component></header-component>
   <main-component></main-component>
   <footer-component></footer-component>
</body>

header.component.html

<div>some header elements...</div>

main.component.html

<mat-sidenav-container>
   <nav>
      <mat-sidenav></mat-sidenav>
   </nav>
   <main>
      <mat-sidenav-content></mat-sidenav-content>
   </main>
</mat-sidenav-container>

footer.component.html

<div>some footer elements...</div>
  1. As mentioned earlier, utilizing semantic HTML5 tags in Angular does not hold much relevance.
