Open challenge → - Inline vs Block Elements

Open challenge → - Lists and Navigation

Open challenge → - Semantic Page Layout
Build a semantic page layout using header, nav, main, section, article, and footer. Focus on correct landmarks, heading hierarchy, and structure rather than styling or layout hacks so the document outline remains clear…
Open challenge → - SEO: Essential <head> Metadata
You’re given a simple marketing page that renders fine in the browser, but it’s missing production-grade <head> metadata. Update ONLY the <head> so the page has correct encoding, mobile-friendly viewport beh…
Open challenge → - Forms: Validation and Required Fields
Build a signup form using native HTML5 validation: required fields, type constraints, minlength, and pattern. The browser should block invalid submissions without custom JS changes, and existing JS/CSS should remain unt…
Open challenge → - Modal: Native <dialog> Confirm (Accessible Naming)
Build a native confirm dialog for deleting a project using the HTML <dialog> element. The dialog must be accessible (proper name + description) and must be visible in the preview without JavaScript. Only edit HTML…

You can make an image clickable by wrapping it in an anchor tag. This creates a linked image that behaves like a normal link and is accessible when you include alt text and descriptive link context. Use rel=noopener whe…

Open question → - What are semantic HTML elements?
Semantic HTML elements clearly describe their meaning in a way that both browsers and developers can understand. Unlike generic containers such as <div> or <span>, semantic elements like <header>, <…
Open question → - What does the <br> tag do?
The <br> tag inserts a line break inside text content. It’s an empty element and should be used for line breaks in prose, not for layout (use CSS for spacing). Use it only for semantic line breaks (addresses, poem…
Open question → - What does the <title> tag do?
The <title> tag defines the title of an HTML document. It appears in the browser’s title bar or tab and is used by search engines and social networks to identify and display the page. Though not visible within the…
Open question → - What is the default method for form submission in HTML?

Block-level elements start on a new line and take up the full width available, while inline elements stay within a line without breaking the flow of text. They play different roles in structuring and styling HTML docume…
Open question → - What is the difference between id and class attributes in HTML?
Both id and class are used to identify HTML elements, but they serve different purposes. The id attribute uniquely identifies a single element, while the class attribute groups multiple elements under a shared name for…
