possible to use more time an element like aside and other elements?
possible to comebine the main element tag with aside and section because as main is main content but aside is not main content so main inside aside tags??
is matter where i choose to use header tag i mean not with h2 tags?
Hi, yes, but caution is advised because search engines make use of your semantic tags
to determine the content of your website
There are some rules to follow.
I suggest to read this
With HTML4, developers used their own id/class names to style elements: header, top, bottom, footer, menu, navigation, main, container, content, article, sidebar, topnav, etc.
This made it impossible for search engines to identify the correct web page content.
With the new HTML5 elements ( <header> <footer> <nav> <section> <article> ), this will become easier.
According to the W3C, a Semantic Web: “Allows data to be shared and reused across applications, enterprises, and communities.”
