You can add comments to your HTML source by using the following syntax:<!– Write your comments here –>
Notice that there is an exclamation point (!) in the start tag, but not in the end tag.
Add Comments
With comments you can place notifications and reminders in your HTML code:
Example
<html>
<body>
<!– This is a comment –>
<p>This is a paragraph. </p>
<!– Comments are not displayed in the browser –>
</body>
</html>
Result:
This is a paragraph.
Hide Content
Comments can be used to hide content.
Which can be helpful if you hide content temporarily:
Example
<html>
<body>
<p>This is a paragraph.</p>
<!– <p>This is another paragraph</p> –>
<p>This is a paragraph too.</p>
</body>
</html>
Result:
This is a paragraph.
This is a paragraph too.
You can also hide more than one line, everything between the <!-- and the --> will be hidden from the display.
Example
Hide a section of HTML code:
<html>
<body>
<p>This is a paragraph.</p>
<!–
<p>Look at this cool image:</p>
<img border=”0″ src=”pic_trulli.jpg” alt=”Trulli”>
–>
<p>This is a paragraph too.</p>
</body>
</html>
Result:
This is a paragraph.
This is a paragraph too.
Comments are also great for debugging HTML, because you can comment out HTML lines of code, one at a time, to search for errors.
Hide Inline Content
Comments can be used to hide parts in the middle of the HTML code.
Example
Hide a part of a paragaph:
<html>
<body>
<p>This <!– great text –> is a paragraph. </p>
</body>
</html>
Result:
This is a paragraph.
