In addition to the already discussed components, SAS offers some instructions permitting us to perform
some operations with the aim of simplifying even more the compilation of these files.
The first instruction we will see is the extent instruction, which along with a placeholder that is
a selector made up by the singular percentage and a name, we have the possibility to adopt a series
of properties which might be then recalled into the already present selectors.
For example, we have inside body color and font family, which recall two properties that are color
select and font select, obviously font select area.
In this case, makes the insertion of the same font valid for the whole page, apart from logically
for the change just performed.
If we decide to delete these two values and create in the place a placeholder by calling it, for example,
font color, we might create an actual selector with color black.
And fun family area.
Obviously, in this moment, if we saved the system would find it awkward as Carlos Selek and select
and not present among the variables anymore.
So for example, in Bunnie we have to delete them and insert extend the function above mentioned with
a percentage font color as an attribute.
We can of course do the same thing also.
As for Pete.
And as for Miller, this is because given the fact funned family area is a superfluous attribute, if
we perform these replacement, the system permits to correctly compile the fight by going to insert
the same fund family also into these other attributes.
Therefore, we will see that extend does work correctly anywhere.
And so let's see and see that the system has performed the desired operation and has covered all the
various fields, all the various selectors that matter to us, to which the extent, font, color attribute
has been given and therefore it's simplified even more.
The CCSVI created, of course, the system didn't perform any type of change as to our in browser,
viz. because the features are the same.
But the final says we turn out to be additionally simplified.
