Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
One tag, no closing — that's how images load.
HTML images are inserted with the <img> tag. It is a void (self-closing) element — it has no closing tag and no content inside it.
↳ <img> is self-contained: it references an external file, not inline content.
src and alt — the non-negotiables.
↳ Without src, nothing loads; without alt, the image is inaccessible.
alt is not just a fallback.
↳ alt is accessibility, fallback, and SEO in one attribute.
HTML images are embedded using the tag, a void element that pulls an external image file into a web page. Mastery involves understanding required attributes (src, alt), sizing, formats, responsiveness, and accessibility...

18 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which statement best describes what an `<img>` tag actually contains?
BeginnerA pointer that tells the browser where to fetch the image
The `` tag does not store pixels. It is a placeholder that instructs the browser to fetch an external file and paint it in place. The actual image data lives in a separate file such as `.jpg` or `.png`.
A student writes `<img src="logo.png">` with no other attributes. Which attribute is missing that is required for accessibility?
Beginner`alt`
`alt` is the alternative-text attribute required for accessibility. Without it, screen readers may read the filename aloud and users on broken connections see nothing useful.
Which of these is a void element with no closing tag?
Beginner`<img>`
`` is a void element — it has no closing tag and cannot contain child content. The other three are container elements that wrap content.
A designer places a purely decorative divider image on a page. What should the `alt` attribute be?
Beginner`alt=""` (empty)
An empty `alt=""` tells assistive technology to skip the image, which is correct for decoration. Omitting `alt` entirely is worse because screen readers may then read the filename aloud.
