00:00:05,200 --> 00:00:14,020
The image you're watching right now in this video represents the syntax of the stylesheets, as you

2
00:00:14,020 --> 00:00:18,760
can see, we have some selectors in this specific case.

3
00:00:18,790 --> 00:00:23,380
They are two and some properties associated to each of them.

4
00:00:23,920 --> 00:00:33,070
In any type of stylesheet, we will have the opportunity to define all a series of properties associated

5
00:00:33,070 --> 00:00:43,000
to age HTML tags, like, for example, the paragraph tag or the Dave Tag or others among those seen

6
00:00:43,000 --> 00:00:52,330
within the HDMI relative section, which are going to format the content according to what we have chosen

7
00:00:52,330 --> 00:00:54,390
for every single part of them.

8
00:00:55,240 --> 00:01:04,180
When the stylesheets were born with the success in version one, you could perform limited modifications.

9
00:01:04,600 --> 00:01:13,660
In fact, you could attribute some properties to fonts, modify colors and backgrounds and act on other

10
00:01:13,660 --> 00:01:16,210
minor text formatting properties.

11
00:01:17,150 --> 00:01:25,520
The code you see inside this image is the perfect example of the way the age symbol used to act before

12
00:01:25,550 --> 00:01:27,170
this VSS were born.

13
00:01:29,400 --> 00:01:38,130
Soon after the appearance of this success version one, we move to what is the first evolution of the

14
00:01:38,140 --> 00:01:48,000
standard that the access to the main innovation introduced in the version to deals with the opportunity

15
00:01:48,000 --> 00:01:58,040
to create a separate stylesheet for mobile devices in the new technical specifications of the version.

16
00:01:58,590 --> 00:02:08,430
There are also new downloadable phones and other small properties regarding the user interface.

17
00:02:09,600 --> 00:02:17,970
Once achieved the version three of the success we obtained, what is the perfect match for the Web development

18
00:02:17,970 --> 00:02:24,790
so that HTML and Cyesis together can be considered a programming language?

19
00:02:25,750 --> 00:02:33,310
This new version in comparison with the previews has been created in a modular way and in fact, there

20
00:02:33,310 --> 00:02:38,050
are a series of modules dealing with the various features of the language.

21
00:02:38,590 --> 00:02:45,610
In addition to the new selectors, for example, the responsive design in this case is managed by a

22
00:02:45,610 --> 00:02:54,100
module dedicated to the menu queries which enable the age to amount pages to be perfectly displayed

23
00:02:54,100 --> 00:02:55,210
in any device.

24
00:02:55,210 --> 00:03:01,360
In the following lessons, we will see all the main features of the CSF version three.

25
00:03:02,680 --> 00:03:11,560
As a topic, don't forget that these course we also cover the access framework called Bootstrap, which

26
00:03:11,560 --> 00:03:19,450
with the incoming of this version of the stylesheets, is one of the several protagonists we come across

27
00:03:19,720 --> 00:03:22,450
within the major websites of the Net.
