Change border color for every cell of a table

jdang67 · February 23rd, 2006, 04:56 PM

Hi all,

I want to change the border color of every cells or rows of a table but I am not quite sure what is the best way to do it. Personally, I want to change on the table level, not on cells or rows object.

Setting border=1 on table tag will turn all border on but when we try to change border color then only 4 sides border are changed and inside are not. Does anybody know how to do this?

Take the HTML border attribute away, and apply the following CSS between <head> and </head> tags.

Code:

<style type='text/css'>
    table, td {
        border: 1px solid black;
    }
</style>

That border applies to all <table> and <td> elements in a given document.

HTH!

Regards,
Rich

CSS handles borders os TABLE and TD (and TH) separately.

For all tables.
table,td,th { border: 2px solid #f00 }

If you want to affect just one table, you have to use a more specific selector (for instance by giving the table an id or class).

Is there a way to change the border color of each row?

Give them different CSS classes.

That's what I figured, but it didn't work. Is the code like this?

Code:

<tr class="example">
<td>Hi </td>
<td>Hello </td>
</tr>
<tr class="test">
<td>Test </td>
<td> Testing </td>
</tr>

And the style sheet looks like this?

Code:

tr.example {
border-color:red;
All other border stuff in here;}

tr.test {
border-color:gray;
All other border stuff in here;}

For example:

Code:

<html>
<head>
<style>
<html>
<head>
<style>
table {
	border-style:solid;
	border-width:1px;
	border-color: yellow;
}
tr.example td {
	border-style:solid;
	border-color:red;
	border-width: 1px;
	padding: 10px;
}
tr.test td {
	border-style:solid;
	border-color:green;
	border-width: 1px;
	padding: 10px;
}
</style>
</head>
<body>
<table>
<tr class="example">
<td>Hi </td>
<td>Hello </td>
</tr>
<tr class="test">
<td>Test </td>
<td> Testing </td>
</tr>
</table>
</body>
</html>

</table>
</body>
</html>

could it be that my browswer doesn't support that when using <tr>?
I think it said in the book that some browsers can't support <tr>, so instead you should use <td>, but I tried that also, and it didn't work.
And I even tried it in one of the W3Schools.com "Try it out yourself" activities, and it worked.

Actually in my example, the style is applied on td, not tr. tr is there merely as a selector to narrow down to a particular group of td's.

I just tested my last example as is with IE8, Opera, Firefox, Safari and Chrome, all with the latest version on Windows, and they all worked.
