Is it okay to learn HTML4 now? Will it become outdated? _html/css_WEB-ITnose

I downloaded this HTML CSS introductory classic, but it talks about HTML4. Can I continue learning? Will it become outdated?

I am also learning, so learn it first. HTML5 only adds new features. You can learn 4 and then 5. You can take a look at this http://bbs.csdn.net/topics/380157319

However. Master the basics first before you can learn more.

Try to learn the technology after excessive xhtml

For China, which still accounts for 20% of IE6 users in the world, I can tell you clearly that HTML4 is still the most popular in China~

What about Firefox and Chrome?

The popularity of Firefox and Google browsers in China is really low. One is banned in the mainland and needs to be circumvented, and the other is highly targeted because it is mostly used for development. And in China, basically all computer systems are WINDOWS, but the IE browser it comes with is not compatible with HTML5, at least not yet~

It’s outdated. Now when companies recruit front-end people, they will ask if they know some HTML5 , I recommend "Crazy HTML5, CSS3, JAVASCRIPT" and "Sharp Jquery". After reading these two books, you are almost done.

If you don’t learn HTML4, you are kidding me. . .

Yes

html5 is an extension of html4 and adds many new features. However, not all browsers are now fully compatible with these features, so html4 is still Quite important.

First, you must understand the difference between HTML4 and 5:
1. Both 4 and 5 are standards for HTML. The main difference is that in the 5 standard, some more tags are added than 4 (such as header footer nav...),
adds some more functions (such as: canvas vedio localstorage...)
2. 5 is backward compatible, and the tags of 4 can basically be used in 5
3. So roughly speaking, 4 and 5 are just a distinction from simple to advanced. Newbies can use ordinary tags to make ordinary pages.
For better ones, they can be more semantic and use 5 tags css2/css3. Special effects of css3
4. The most important part of the last 5 is the application of mobile pages. Since mobile phones are basically webkit kernels (except for window phones, IE11 also supports 5 very well),
There is no compatibility Troubled, the support is good, so now H5 CSS3 JS is shining brightly on mobile pages, this is what you need to pay attention to!

Oh, I understand. This means that there is no problem in learning 4 first and then 5. Please tell me again. I mainly want to do the backend. I don’t know how much I need to know about 5?

At present, many tutorials are misleading novices. Of course, they do this for commercial interests. They say that learning xhtml is outdated. In fact, it is not outdated at all. In actual work, xhtml technology is mainly used. , of course, you can also just write HTML5, but that is just for writing mobile websites. Even for writing mobile websites, xhtml is also the most practical. I advise those without conscience not to mislead novices.

If you don’t learn html4, what do you know about html5?

Don’t be out of date, learn HTML4 well, then learning 5 will be easy
