1
00:00:05,200 --> 00:00:13,360
In addition to the already discussed components, SAS offers some instructions permitting us to perform

2
00:00:13,360 --> 00:00:20,450
some operations with the aim of simplifying even more the compilation of these files.

3
00:00:20,650 --> 00:00:27,910
The first instruction we will see is the extent instruction, which along with a placeholder that is

4
00:00:27,910 --> 00:00:35,320
a selector made up by the singular percentage and a name, we have the possibility to adopt a series

5
00:00:35,320 --> 00:00:41,420
of properties which might be then recalled into the already present selectors.

6
00:00:41,710 --> 00:00:49,680
For example, we have inside body color and font family, which recall two properties that are color

7
00:00:49,700 --> 00:00:54,950
select and font select, obviously font select area.

8
00:00:54,970 --> 00:01:02,950
In this case, makes the insertion of the same font valid for the whole page, apart from logically

9
00:01:03,310 --> 00:01:06,020
for the change just performed.

10
00:01:06,040 --> 00:01:15,910
If we decide to delete these two values and create in the place a placeholder by calling it, for example,

11
00:01:15,910 --> 00:01:21,370
font color, we might create an actual selector with color black.

12
00:01:22,180 --> 00:01:26,010
And fun family area.

13
00:01:27,540 --> 00:01:36,200
Obviously, in this moment, if we saved the system would find it awkward as Carlos Selek and select

14
00:01:36,330 --> 00:01:39,110
and not present among the variables anymore.

15
00:01:39,120 --> 00:01:46,890
So for example, in Bunnie we have to delete them and insert extend the function above mentioned with

16
00:01:47,040 --> 00:01:50,940
a percentage font color as an attribute.

17
00:01:51,150 --> 00:01:54,150
We can of course do the same thing also.

18
00:01:55,490 --> 00:01:56,720
As for Pete.

19
00:01:58,450 --> 00:02:08,590
And as for Miller, this is because given the fact funned family area is a superfluous attribute, if

20
00:02:08,590 --> 00:02:17,050
we perform these replacement, the system permits to correctly compile the fight by going to insert

21
00:02:17,050 --> 00:02:21,430
the same fund family also into these other attributes.

22
00:02:21,430 --> 00:02:26,900
Therefore, we will see that extend does work correctly anywhere.

23
00:02:27,070 --> 00:02:35,800
And so let's see and see that the system has performed the desired operation and has covered all the

24
00:02:35,800 --> 00:02:46,180
various fields, all the various selectors that matter to us, to which the extent, font, color attribute

25
00:02:46,210 --> 00:02:50,250
has been given and therefore it's simplified even more.

26
00:02:50,590 --> 00:03:00,190
The CCSVI created, of course, the system didn't perform any type of change as to our in browser,

27
00:03:00,190 --> 00:03:03,910
viz. because the features are the same.

28
00:03:04,420 --> 00:03:09,310
But the final says we turn out to be additionally simplified.
