How to ensure that the size of a table or DIV in JSP or HTML is not changed by inserting a form?

How to ensure that the table or Div does not change the size because the form is inserted?

I. Problem description: in JSP/html, after a form is inserted into a table or Div, the table or Div increases, affecting the original layout.

Ii. Method of Liberation:

In this case, setting the table <TD> or Div's height and width does not work. The following method can solve this problem:

Method 1: Set overflow: hidden in TD, so that the excess part is not displayed.

<TD Height = "25px"Style = "overflow: hidden">

Or <Div Style= "Overflow: hidden; 100px; Height: 25px; float: Left; ">

Add overflow: hidden; to the DIV style so that the DIV will not become larger even if the content in the DIV is too large.

Method 2: directly set the padding and margin attributes for the form, or directly set the attributes in CSS or

CSS: FORM {Padding: 0px; margin: 0px;}

Set directly;

<HTML: Form Action = "/admindeletenews. Do" method = "Post"Style = "padding: 0px; margin: 0px ;">

3. Practice has proved that this has been achieved.
