Giving a border to an HTML table row, <tr>

The Solution to Giving a border to an HTML table row, <tr> is

You can set border properties on a tr element, but according to the CSS 2.1 specification, such properties have no effect in the separated borders model, which tends to be the default in browsers. Ref.: 17.6.1 The separated borders model. (The initial value of border-collapse is separate according to CSS 2.1, and some browsers also set it as default value for table. The net effect anyway is that you get separated border on almost all browsers unless you explicitly specifi collapse.)

Thus, you need to use collapsing borders. Example:

table { border-collapse: collapse; }
tr:nth-child(3) { border: solid thin; }
