What Is a Comment in HTML?
HTML comment (multiple lines) – what is it? A comment in HTML is used to insert text that will not be displayed when the HTML document is viewed in a web browser.
When coding in HTML, there may be times when you need to add comments that are multi-lined. Maybe you’re troubleshooting some issues and want to quickly disable a section of your code, or maybe you want to add some notes for yourself or other developers working on the same project. Whatever the case may be, commenting out multiple lines in HTML is actually quite simple.
HTML Comment – Multiple Lines (Comment Tags)
HTML comment (multiple lines) – how to do it?In HTML, there are two ways to multi-line codes. Good practice is to start your multi-line comment with an opening HTML tag, and then add your text. The first way is to use the standard HTML comment (multiple lines) tags and use the following syntax:
<!--This is my commented out code.
It won’t show up when the page is rendered in a browser.
-- >You can comment out as many lines as you want using this method. Just make sure that your opening comment tag (<!–) is on its own line, and that your closing comment tag (–>) is on its own line as well. Everything in between those two tags will be treated as a comment.
The second way to comment out multiple lines in HTML is to use the server-side comment tags, like so:
<!--This is my commented out code.
It won’t show up when the page is rendered in a browser.
--%>Just like with the HTML comment tags, everything between the opening (<%–) and closing (–%>) tags will be treated as a comment.
Now that you know how to comment out multiple lines in HTML, you can use this technique whenever you need to quickly disable a section of code or leave yourself a note. Just remember to use the proper opening and closing tags, and your comments will stay hidden from view.
When Should You Comment Out in HTML?
HTML comment (multiple lines) – why is it done? There are a few different reasons why you might want to comment out code. Maybe you’re troubleshooting some issues and want to quickly disable a section of your code, or maybe you want to add some notes for yourself or other developers working on the same project.
Source code comments are notes that you add to your HTML code to explain what’s going on. They don’t show up when viewed on a web browser, but they’re very helpful for you and other people who might need to read or edit your code.
Whatever the case may be, commenting out code can be a helpful way to make changes to your HTML without actually changing the code itself.
One common reason for commenting out code is that you want to disable a certain section of your code without deleting it entirely. This can be helpful if you’re troubleshooting some issues and need to quickly comment out a large chunk of code. It’s also useful if you’re working on a project with other developers and want to temporarily disable a section of code that you’re not ready to commit just yet.
Another reason you might comment out code is to leave yourself or other developers notes about the code. This can be helpful if you’re working on a complex project and need to remind yourself what a certain section of code does. It can also be useful for other developers who are working on the same project and might need some guidance on what a certain section of code does.
Single Line Comment and Multi-Line Comment in HTML
The main difference between HTML comment multiple lines and single line is that a single-lined comment can only span one line, whereas a multiple-lined comment can span multiple lines. In addition, multiple-lined comments can be nested, meaning that one multiple-lined comment can appear inside another multiple-lined comment. This can be useful for temporarily commenting out large sections of code.
HTML Comment (Multiple Lines) – The Bottom Line
Commenting out code is a helpful way to make changes to your HTML without actually changing the code itself. There are two ways to comment out code in HTML: using the standard HTML comment tags, or using the server-side comment tags. Both methods will hide your comments from view when viewed in a web browser.
So, there you have it! Use this technique whenever you need to quickly disable a section of code or leave yourself a note. Just remember to use the proper opening and closing tags, and your comments will stay hidden from view.
