How Can I Migrate Table Attributes to CSS in HTML5?

HTML5 Table Attributes Transition

Visual Studio's HTML5 validation feature identifies cellpadding, cellspacing, valign, and align attributes as invalid for table elements. To address this, HTML5 introduces CSS alternatives to control the appearance and spacing of tables.

Cell Padding:

Replace cellpadding with the CSS padding property applied to table cells ( and ). For example:

<code class="css">th, td {
  padding: 5px;
}</code>

Cell Spacing:

Replace cellspacing with CSS border-collapse and border-spacing properties applied to the table. border-collapse: separate and border-spacing: 5px will create 5px of spacing between table cells. border-collapse: collapse and border-spacing: 0 will remove all spacing between cells.

Vertical Alignment:

Replace valign with CSS vertical-align applied to table cells. vertical-align: top will align cell content to the top of the cell.

Horizontal Alignment (Center):

While align is not a valid HTML5 attribute, you can achieve horizontal centering using CSS margin: 0 auto applied to the table. This will center the table horizontally within its parent container.
