When developing a website or web application, it's important to keep in mind the difference between an ID and a Class, and to know when to use each one and why.
The primary thing to remember about this is that you should be using an ID for a unique element that only exists once on the document whereas classes are more appropriate for multiple elements that serve the same purpose.
In this video I take you through this topic and how it affects not only your HTML markup but also your CSS code and JavaScript.

Ty I'm doing one of these 5d boot camps to see if coding is something I want to pursue or if my brain can handle it.... and I got hung up on the difference of class and id selectors but you explained it really well. It was a lot easier than I was making it out to be.

Really helped me understand the difference as when I read about it, I didn't really understand. Cheers!

Wow, that makes it all clear now. Now I know I shouldn't be abusing the ID when I work with javascript and the fact that I have should know that ID needs to be unique or that it cannot use its name multiple times. Reading about it confuses me when I only work with html and css as I can use id name multiple times.

i used same id for 3 images in a div element and it worked for all 3 elements why?

@maheephoenix4398 2 жыл бұрын

You could have given that id to the div instead of giving it to imgs separately.

Big help thanks ps how did you copy the div multiple times, what key did you use etc? Thanks in advance

If you had the same title on different pages, I assume you could use the same ID also right?

@AtTheEnd1000 3 жыл бұрын

In a video I watched, the narator said that the ids are used less and less and that classes are becoming more used, just because you can target multiple elements. Is this true in the industry?

@pendek3255 3 жыл бұрын

id can be used one time, class everytime everywhere you want, so yes you are right
