In this article, the editor introduces in detail "what is the basic usage of HTML", the content is detailed, the steps are clear, and the details are handled properly. I hope this article "what is the basic usage of HTML" can help you solve your doubts.

1. Html tags are used to add semantics to the text, not to modify the text.

2. Specify the character set (GB2312, UTF-8). Html saves the same as the specified characters, so as not to garble the code.

3. The DTD document statement tells the browser what protocol I use to write it, not the html tag

4. Webstorm shortcut keys: https://www.cnblogs.com/yeminglong/p/5995421.html

3. Non-input tags

(1) select

(2) textarea

4. Practice

(1) all form tags except button can use value to specify the submitted value.

(2) adding a border to the form can be achieved by adding fieldset to form.

1. Video tag

(1) format:

(2) attributes: controls (control bar) poster (poster) loop (loop) preload (preload, conflict with autoplay) muted (mute) width/height

(3) another video format: solving browser compatibility

(4) make all browsers support video tags: through the js framework

2. Audio tag

(1) basically the same as video, only width and height attributes and poster cannot be used, there are also two formats

3. Details and summary tags

(1) format:

4. Marquee tag (Racing Lantern effect)

(1) W3C is not recommended, but the browser supports it well.

(2) attribute: direction (direction) scrollamount (speed of scrolling) loop (number of scrolls, default-1) behavior (scrolling type slide)

(3) abandoned labels:

Bold underlined italic delete line (no semantic)

Alternative tags: (semantics added)

5. Character entity

(1) & nbsp; spaces & lt;> & copy; copyright symbols

(2) understanding: special characters occupied by html that are not displayed are represented by other symbols instead of symbols, so that they can be displayed normally on the html page.
