All elements are in the div of a iner. This DIV sets padding-top: 0;
The following code is also set for all bodies.
Body table tr td {

 topmargin="0"  leftmargin="0"  rightmargin="0" bottommargin="0" position:relative;  margin:0 auto; width:1000px;}

Body {

margin:0;padding:0;

}

LZ your Writing Method
Body table tr td {

/* some css */

}
In this way, the dom of the selector is not the body, but the td under the tr in the table below the body.
Just add a comma in the middle.
Body, table, tr, td {
/Some css/
}

The lazy statement is:
* {Margin: 0; padding: 0 ;}

Body :{

padding: 0;margin: 0;

}

body table tr td｛***｝

This is not to add a style to the body. This derivative method will eventually add a style to td.
Simply put

body { margin:0;padding:0;}
