Which level of CSS developer are you ?, Level css developers

We are constantly learning and pursuing progress and improvement. To what extent have we learned? What level have we really understood CSS. Let's take a look.

　　Level 0th: CSS? Isn't it a multiplayer shooting game? 
CSS? Isn' t that a multiplayer game?
Some people go to the # CSS website for information about the game CS: S (Counter Strike: Source. Don't worry about these people. They can't make too many webpages, so they won't do much harm to the Internet.

　　Level 1st: Yes, I occasionally use it to remove the bottom line of the link. 
Yeah, I use it to remove underlines on links sometimes
Different from the 0th-level users, these users have learned HTML and made several simple websites. CSS is used only when HTML cannot be used to produce certain effects, such as removing the bottom line of a link or setting the Row Height. The websites of these people are usually small and have no visitors, so they will not cause too much harm to the Internet.

　　Level 2nd: No, I don't like div elements. Tables are much easier to use! 
No, I don't like divs; tables are much easier to work
They have heard of the use of div elements to design webpages and have spent some time learning CSS. However, they quickly gave up and thought CSS was too difficult and had poor support, but they would rather use table layout.
Note! They are dangerous people! They have been in this field for a while, and many of them are website department directors. It is very important to contact them. People who advocate network standards should enlighten them more, which is of extraordinary significance to the network.

　　Level 3rd: Yes, I heard it is quite good, but I didn't use it because ...... 
Yes I 've heard it's good, but I can't use it because...
Although they know the advantages of CSS, they are always unable to use it for some reason. For example, they may have 2nd-level superiors, or they must take into account users of Netscape 4.
Although the old browser does not support CSS, you can still see the complete content. CSS can bring more visitors to the Website Based on the advantages of accessibility and usability. Tell developers of level 1 about these advantages. Even if they are not decision makers, they may be able to exert some influence on their superiors of level 2.

　　Level 4th: CSS? Oh! That's right. I use div elements for layout. 
CSS? Oh! Yes, I use divs for all my layouts
If you use too many div elements on the page, they will use the # toprightredline or # r5_c7 (column 5th in column 7th) set the id of the div element in this way. Even if you can pass the XHTML 1.1 verification, This typographical method cannot take advantage of CSS. Screen readers (a browser used by the visually impaired) is difficult to interpret these web pages. The old version of the browser may have the same problem, and the content of the Web page cannot be completely displayed. Poor class and id naming methods also cause great inconvenience to layout modification.
Although the websites made by hundreds of thousands of people are still very bad, they do not suffer much harm to the Internet because they are easy to accept new ideas. Many WYSIWYG editors make primitive code that is full of div elements, which may mislead this group of people. Fortunately, these editors have been gradually improved, and we hope this will help 4th people continue to improve.

　　Level 1: I use CSS for design, which is much better than the table lattice, because ...... 
I use CSS for design, it's better than tables because...
Level 1 people know the advantages of CSS and are willing to use it. Although they sometimes encounter some problems, they are not serious. They can also use their long-term CSS work experience to argue with people why they should separate the structure and design of the web page. I guess most of the readers of this article are CSS developers at this level. But this is not the best ......

　　Level 6th: Which version of CSS? Yes, I know. You have read my books ...... 
What version of CSS? Yes, I do. Did you read my book about...
6th people are committed to improving CSS and have written many great articles to introduce its new usage. Some of them read all the W3C CSS instruction files and know which features are supported by the browser. They are examples of CSS beginners and use their influence to make the network more progressive. Many of them form the Web Standards Project. If you find any errors on their website, you must have a reason. After asking them, you will be able to get a satisfactory answer.

I use the IE developer tool. Why is there always a lot of line-drawn styles in the CSS list?

This is the inheritance (or overwrite) of the same style. For example, the <body> </body> tag contains the <p> </p> tag and the <p> </p> tag contains the <a> tag, all three tags have the font style attribute. The style attribute on the <a> label can only be the font style defined on the <a> label, and the font style of the <body> and <p> labels is overwritten.
