CSS Selectors

 

You've now learned about three kind of CSS selectors: ​type​, ​class​, 

and ​ID​! 

 

 

 

●

Type​ selectors are used to apply a style to a particular type of HTML element, like ​

h1​

 or 

body​

.  

Type selectors are written using just the type name. 

 

●

Class​ selectors are used to set the style for multiple HTML elements that have a particular 

value for the ​

class​

 attribute.  

You can name a class anything you want! Class selectors are written with a dot before the 

class: for elements such as ​

​

, the class selector is ​

.blue​

. 

 

●

ID​ selectors are used when the style is being applied to one HTML element, which has to 

have an ​

id​

 attribute.  

There can be only ​one ​element with a particular ​

id​

 on a page. You can also choose any name 

you want for an ​

id​

, just like a​

 ​class​

. ID selectors are written using a ​

#​

 sign: for an element 

such as ​

​

, the ​

id​

 selector is ​

#sidebar​

.
