The color in the Gridview column does not fully cover the entire space within

I'm struggling with getting rid of a 1px border around certain highlighted boxes in my gridview. The issue persists on both IE7 and FF.

Update
I managed to resolve the issue by adjusting the item style for the Serial# template. Thanks for the guidance!

<ItemStyle Font-Size="Smaller" CssClass="NoMargin NoPadding" />

Answer №1

To achieve the desired result, try applying the border-collapse: collapse; property to the cssTable class in your CSS.

I managed to resolve the issue by removing the css classes from the first template item and creating a new CSS code snippet as follows:

table.cssTable
{
    border-collapse: collapse;
}

table.cssTable tr td
{
    background: Yellow;
    font-size: Smaller;
    margin: 0;
    padding: 0;
}

Additionally, you can eliminate the ItemStyle with font-size by implementing this CSS solution.

Answer №2

I've taken a look at the fiddle you provided, but unfortunately, I'm not able to identify the issue at this time - http://jsfiddle.net/5rBYb/1/

One suggestion to consider is adding the following CSS code snippet, which should adjust the border settings to a single pixel width (potentially resolving your problem).

table, th, td { border: 1px solid #000; }

If you prefer to hide the borders altogether, simply change it to border: 0.
