Semantic HTML

• Semantic HMTL elements convey a meaning
• You can give your HTML a certain structure which improves screenreader user's orientation (eg. providing <main>, <header>, <footer>, <nav>)
• There are also ARIA role representations for them. Only use them as a last resort.
• Some HTML elements (especially interactive ones like <button>) bring built-in functionality, while with ARIA roles you need to rebuild this functionality on your own.
