Instructions for 6 unusual HTML tags

Time:2021-10-25

First: < abbr > or < acronym >
These two signs are the same thing. They are mainly used for some English abbreviations. When you move the mouse over, you will find a small prompt to prompt the full name of the abbreviation. Here is an example:

<ABBR title=”HyperText Markup Language”>HTML </ABBR>
< abbr title = “Institute of electrical and Electronics Engineers” > IEEE < / abbr >
<ABBR title=”Read the Fucking Source Code”>RTFSC</ABBR>

Second: < Q > this logo is mainly to add double quotation marks to the quoted text. This logo seems very meaningless. Officials say it’s for convenience, but I always think this logo is not as convenient as entering double quotation marks directly. It doesn’t seem to matter. Can this logo only be seen under Firefox, ie does not support it. Here is an example: This is an introduction < Q > this is an introduction < / Q > this is an introduction

Third, < BDO > is an interesting sign. You can reverse the word order from left to right. For example: May I help you sir? If this logo is added, it will look like this: May I help you sir? What can I do for you< BDO dir=rtl>May I help you sir ?</ BDO > < BDO dir = RTL > what can I do for you</ BDO> May I help you sir ? What can I do for you?

Fourth, < del > adds a strikeout to your string. For example, this is a deleted text< Del > this is a deleted text < / del > this is a deleted text

The fifth and sixth, < sub > < sup > are subscripts and superscripts. Here is an example: This is a subscript and this is a superscript. This is a < sub > subscript < / sub >, and this is a < sup > superscript < / sup >
