Why is it important to avoid using heading tags to resize text?
Difficulty level
Because heading tags are meant for playing videos.
Because they are semantically intended to indicate the structure and importance of content, not just for styling.
Because they can slow down page load speeds.
Because they might distort images.
Heading tags, ranging from h1 (most important) to h6 (least important), are primarily meant to convey structural significance in a document. Using them merely for resizing text can mislead search engines and screen readers about the content's importance and hierarchy. Instead of misusing heading tags for styling purposes, CSS should be used to adjust text size and appearance. This ensures that content is both accessible and semantically correct.
You are designing a form that requires users to select their country from a dropdown list. How would you implement and structure the "select" and "option" elements to ensure usability and accessibility?
