3. Top 50 Frontend Developer HTML Interview Questions (Part 1)
Review essential interview questions asked by top tech companies (Google, Meta, Microsoft) to test your HTML depth.
| # | Interview Question | Key Technical Answer |
|---|---|---|
| 1 | What is the difference between inline and block-level elements? | Block elements take 100% width and start on a new line; inline elements only take content width and flow inline without line breaks. |
| 2 | What does `` do? | Enforces standard mode rendering in modern browsers, preventing quirks mode. |
| 3 | What is the purpose of custom `data-*` attributes? | Stores custom data private to the page, readable via JS `dataset`. |
| 4 | What is the difference between <script defer> and <script async>? |
`async` executes immediately upon download (blocking HTML parsing); `defer` executes after document parsing finishes. |
