In this lecture you will get familiar with ceaseless glossies and ideas selectors CCS and classes that

2
00:00:08,330 --> 00:00:13,720
are basically selectors and are used to target specific element of age.

3
00:00:13,900 --> 00:00:21,280
It is the vehicle when you play it is a human element uniquely It is our unique identifier.

4
00:00:21,630 --> 00:00:27,170
Once you use it for one element the same idea can not be used as fit in the same document.

5
00:00:27,180 --> 00:00:34,810
For example if you have a paragraph ID you cannot have the same ID any of that a paragraph.

6
00:00:34,810 --> 00:00:42,970
Each element can have on one ID each page can have on one element with dead ID on the other.

7
00:00:43,030 --> 00:00:46,080
Hence classes are not unique.

8
00:00:46,140 --> 00:00:49,100
You can use the same class on multiple elements.

9
00:00:49,230 --> 00:00:52,550
You can use multiple classes on the same element.

10
00:00:54,430 --> 00:01:00,880
It is a design question of when to use ID and when to use class and its taking information that needs

11
00:01:00,880 --> 00:01:07,180
to be applied to multiple objects on how it should be done with a class in next lecture.

12
00:01:07,230 --> 00:01:14,230
I would start adding classes and ideas to elements so you can apply CSSA to these Elliman see you in

13
00:01:14,230 --> 00:01:15,080
next lecture.

14
00:01:15,190 --> 00:01:15,610
Thanks.
