I more or less agree with you, but sometimes it's technically a little
more difficult than that. The border attribute on the table tag
affects not only the table itself, but also the cells inside it. The
CSS attribute only draws a border around the table. I believe the CSS
equivalent of how most browsers (I tested Fx 3.6.8, IE 7, Google
Chrome 5, Opera 10.53, and Safari (Windows) 5.0.1) render <table
border="1"> takes a little more:
table.my_table,
table.my_table > thead > tr > th,
table.my_table > tbody > tr > th,
table.my_table > tfoot > tr > th,
table.my_table > thead > tr > td,
table.my_table > tbody > tr > td,
table.my_table > tfoot > tr > td
{
border: solid 1px black;
}
And, of the browsers listed above, IE7 did not render the table
correctly. (I'm guessing it must not properly handle the child CSS
selectors.) If you do it without the child selectors:
table.my_table,
table.my_table th,
table.my_table td
{
border: solid 1px black;
}
All the browsers render it the same, but it has the side effect that
cells in nested tables also inherit the borders unless you do
something to exclude them:
table.my_table,
table.my_table th,
table.my_table td
{
border: solid 1px black;
}
table.my_table table,
table.my_table table th,
table.my_table table td
{
border: none;
}
As is often the case with CSS, that's a good bit more text to
accomplish the same effect as an older, smaller attribute. :-)
