The class and Ivy selectors are the most important selectors within the says because they get used in
relation to the class and the attributes which are inserted in the various age HTML tags.
Therefore, every specific insert, the selector with the relative name, the class or ID has then the
aim of identifying a specific tag and to attribute to the rules which we get inserted in the stylesheets.
The difference between the two selectors lies in the fact that Class four meets the inserting of the
identifying tag more than once within the document, whereas every ID can appear only once within it,
given the fact it is a univocal identifier before everything.
Let's open our age html five dot age HDMI file.
As you surely remember from the previous lesson we inserted within this paragraph, the span tag to
contain this short sentence.
Span can specify some stylesheets rules, recalling classes, I.D., or inserting them straight away
in inside.
In this case, let's start inserting a class which we we call class one.
In so doing, we can attribute to this specific class three established rules thanks to the stylesheet.
Therefore, getting back to our stylesheet, we can use through the dart attribute our class one which
we insert previously.
Doing so, any type of property inserted into Class one will Fermat exclusively the content of spam
plus one.
We can do the same thing, inserting another spane into this other statement, using an I.D., therefore
the one.
Let's close before the coma and also in this case within style, this time with the hashtag.
We can insert Idy one.
In so doing, exactly like for class.
The idea will enable to attribute specific rules to this specific content, as mentioned at the beginning,
plus an idea are the main selectors types used in the stylesheets.
Therefore, you will find a lot of these selectors, above all the class selectors, which can be inserted
even more than once within a document and in with in any pre-existence tipsheet you are going to work
on or really create some more to specify better the formatting of your e-mail pages.
