How do you "comment out a line"

Installing something and it asks me to "comment out a line."

what does that mean?

thanks

 

<!-- This is a comment in HTML -->

Code (markup):

 

This for perl or .htaccess #
and I think // for php.

 

< !-- is for HTML

you can use // or /* stuff */ for PHP

 

And

[B]/* comment */[/B]

Code (markup):

for CSS.

 

In CSS you need to use
/ * Comment goes in here */

but with out the space between the first / and *

This is the same as a comment block in PHP.

 

Aha! lol, it took my entry out, didn't notice it until you posted yours. Thanks for that

 

i think you can do this too in html
//

 

It means that to prevent a particular line in the script from running, you need to turn it into a "comment". Script comments are not read by the processor, and mostly contain only information for people reading the script's source code.

E.g. (in HTML)

<P>And I really love this</P>
<!-- Comment out next line if you don't wish to tell people that you aren't normal -->
<P>I am a homosexual</P>

Code (markup):

If you follow the instructions:

<P>And I really love this</P>
<!-- Comment out next line if you don't wish to tell people that you aren't normal -->
<!-- No way, I am not even a homosexual to BEGIN with! <P>I am a homosexual</P> -->

Code (markup):

The best part? You don't even have to worry much about which comment symbol to use for the different language: Just use the one which is used for the line that tells you to comment out other lines! (<!-- and --> in this case)
