Take a tour of a workflow that optimizes CSS code for easier navigation, organization, and readability. In this course, author Justin Seeley covers best practices for writing CSS in an easy-to-read format, commenting code, developing a table of contents, and adopting other methods that help produce "cleaner" code. The course also contains tips for speeding up development with some online tools and simplification techniques.
If and when you need to insert multiple lines inside of a comment, it's always a good practice to do what I called creating separator lines so that people understand that this is a huge block of comment that they need to pay attention to. Now if you've already watched the movie on Developing a CSS Table of Contents, you know exactly know what I'm talking about here. And there's a lot of different ways that people do this, and I'm going to show you a couple of those different ways now. So, in order to start a comment, of course you want to start with just a plain old basic syntax for writing out your comments. So you want to do the slash and then an asterisk to start it off, but if you're doing a multi-line comment, my suggestion is to just keep the asterisks going across, and I would suggest going about halfway across the page if not more.
And then after that if you really want to create some space in here you can add another line of asterisks to this, this is really calling attention to whatever it is you're putting in there. And then you can start typing out your comments. So if you've seen my Table of Contents document, this is how I start off my table of contents and then I come in and type out something like, Section 1, header, Section 2, Body, et cetera. To close up the multi-line comment, all you have to do then is start typing out your asterisks again, get that all the way there, and all the way over like this, and once you get to the very end.
just close it with a trailing slash, like so. So you can see this is a more prominent thing, it also has a lot more space in the middle, we can write out multiple lines of comments. This is going to be for like big explanations of what's going on, defining big areas of content like headers, footers, bodies, defining the table of contents, all that kind of stuff. It can also be used as a declaration block at the top of your CSS to do things like who you are, so you could say something like, Author, you put in something like your website address, I mean all this different stuff, attribution to yourself, basically is what this amounts to.
And so, this is really just going a long way to calling attention to something and also separating it out from the rest of this information as well. Now, if you don't like this way of commenting, that's okay, you can also change it up a little bit, as long as you do the slash asterisk you could also do something like hyphens for this, and so you could do something like this, you go all the way across like that, and then you could do something like, This is my comment. Thanks for reading.
And then you can add some more hyphens underneath there. But just remember at the very end of this you do have to close it with an asterisk and a slash, something like that. And so again, it's up to you how you do this. In the end, I would recommend that you come in and play with this and develop your own style, but multi-line comments, things that span multiple lines or multiple paragraphs need to be well defined and they need to be highlighted in such a way that people understand exactly where they start and stop. And so, using techniques like I've just shown you here goes a long way towards doing that.
