Introduction to the difference between html and
Is the align=left of image text body table tr th td music etc. the same as center? Do these basic elements have both methods? Does music have alignmentproperties?
tr td th is centered relative to the table. Others are centered relative to the body?
And the image is centered relative to the text (compared with the text), right? When the image is used alone, there is no "align=", right?
There is no other text in the body, right? font align=> "body align=" is not right either?

The effect is as follows:

Many have alignment attributes such as table, p, div, etc., but not all of them can. Specifically which elements support align, I suggest you don’t memorize it. Write it in when needed and see if it doesn’t work. Just think of other methods (such as putting a container outside that supports align, such as
