bookUsing Developer Tools for HTML Inspection and Debugging

Developer Tools

Modern browsers include built-in developer tools that let you inspect and debug HTML, CSS, and JavaScript. You can access them by pressing F12 or by right-clicking the page and choosing Inspect.

For instance, let's examine the google.com web page. By pressing F12, you can access the following view:

  • The Elements tab (left side) shows the page's HTML structure;
  • The Styles tab (right side) displays CSS rules for the selected element.
  • Hovering over an element highlights it on the page.

In addition to inspecting elements, developer tools allow you to modify HTML and CSS. Changes made are instantly reflected on the webpage but are not permanently saved to the source code. This feature is useful for testing and experimenting with markup and styles.

Code Style

Code style means writing HTML that is clean, readable, and consistent. While HTML does not enforce strict formatting rules, good structure makes your code easier to maintain.

Example of well-formatted markup:

index.html
