Add Comment Tag in HTML to Comment Out Code Line !

Do you know what is an HTML comment, and why should you use it? HTML comments are a simple yet powerful way to add remarks in your code without affecting how the webpage looks. They're mainly used to explain lines of code, leave helpful notes, or temporarily hide parts of your page like a box, form, or section. Comments help you stay organized, especially when working on larger websites or blog pages. With a clean and easy-to-understand syntax (`<!-- comment -->`), adding comments is a smart habit for both beginners and professionals. From marking sections to noting down changes, comments make editing and debugging your HTML code much smoother. If you're ready to level up your coding workflow, here is a detailed blog post on 'HTML comment'.

What Is an HTML Comment?

An HTML comment is a simple way to leave a remark in your code without showing it on the website. It helps you organize, explain, and debug your HTML code easily. Comments are ignored by browsers, so they don't appear on your webpage.

Why Use HTML Comments?

  • To explain each line of code for yourself or other developers
  • To leave notes inside your HTML document
  • To hide parts of a page temporarily without deleting the code
  • To organize sections in a long HTML file
  • To keep track of changes in blog or website development

Using comments is a good practice when building any free or professional website.
