Troubleshooting border styling problems on an iPad for a table

I'm encountering a CSS issue specifically on iPad devices when rendering the HTML page. Oddly enough, everything appears fine on other browsers. The problem I'm facing is a small space between the cells in my tables as shown in this image:

Strangely, if I zoom in to maximum on the line between the cells, the spacing disappears. This leads me to believe it's some sort of bug during the rendering process. Is there a workaround for this issue? Here's the table and CSS code:

<table class="smallTable" cellpadding=0 cellspacing=0>
    <tr>
        <td class="td1"></td>
        <td class="td2"></td>
    </tr>
    <tr>
        <td class="td1"></td>
        <td class="td2"></td>
    </tr>
</table>

CSS:

.smallTable 
{
    margin: 20px auto 40px auto;
    border-spacing: 0;
}

.smallTable td
{
    margin: 0;
}

.smallTable td.td1 
{
    background: url(../images/table1.png);
}

.smallTable td.td2 
{
    background: url(../images/table2.png);
}

After struggling with a bug for hours, I finally figured out the culprit while attempting to create an HTML email.

iPads seem to have a glitch when it comes to displaying tables at anything other than a 1:1 scale. This issue becomes more noticeable if your table's TD tags have a dark background and the parent TABLE has a light color. The use of rowspan and colspan only makes matters worse.

Initially, I suspected that iPad was adding a border where there shouldn't be one. However, the real issue lies in Apple's inconsistent approach to rounding fractions of pixels during scaling.

As a result, some TD tags may appear to have a border when viewed below 100% scale, when in reality, it is just the lighter background showing through.

The workaround is to enclose the table within another table with a matching dark background.

It feels like we're back in the 1998 era of web design. Maybe I'll hop on over to mp3.com or order some dog treats from pets.com. Thanks, iPad!

After encountering an issue with my website on iDevices (iPod, iPad, iPhone), I managed to resolve it by inserting this crucial meta tag into the html head whenever the device is detected in the request.

<meta content='width=device-width; initial-scale=1.0;' name='viewport' />

I hope this solution proves helpful for anyone facing a similar problem.

Success! I finally discovered a solution that resolved my issue.

My tables had borders revealing themselves in a light grey background, making them stand out from the darker color I originally chose.

The fix was to enclose all affected tags within a separate table of the same color to prevent the border issue.

After attempting numerous solutions, this one finally did the trick. Hopefully, this advice proves helpful to others facing similar challenges.

After implementing Zheileman's solution, my tabs with CSS image backgrounds are now displaying correctly on iPad. Check out the top menu tabs on while using an iPad to see the fix in action.

This is the PHP code I used for detecting and adding the necessary META tag:

if (isset($_SERVER['HTTP_USER_AGENT']))
{
    $ua = strtolower($_SERVER['HTTP_USER_AGENT']);
    if (strpos($ua, 'ipad') !== false || strpos($ua, 'ipod') !== false ||strpos($ua, 'iphone') !== false)
    {
        print '<meta content="width=device-width; initial-scale=1.0;" name="viewport" />';
    }
}

One common strategy for handling table styles on websites is as follows, which may help resolve your problem:

table { border-collapse: collapse; }

Additionally, you can safely eliminate the margin settings for your table cells as they have no impact.

I came up with a unique solution to this problem.

Instead of trying the conventional methods, I decided to add a <div> element inside each problematic cell. If there was content in the cell, I made sure the <div> came after it and didn't wrap around the content. I then assigned the classes ios-table-fix to the <div> and ios-table to the table cells (<td>).

After that, I wrote specific CSS rules within media queries targeting the resolution of an iPad screen. To ios-table, I added:

overflow: hidden;
position: relative;

And for the ios-table-fix, I included the following styles:

bottom: -1px;
left: -1px;
position: absolute;
right: -1px;
top: -1px;
z-index: 1;

To prevent any disappearing content inside the table cells, make sure to apply position: relative; and z-index: 2;.

This method effectively eliminates the border issue by creating a new background for the table cell without altering its size. Since this is specifically for iPads, we can safely use CSS within the <head> tag without affecting other devices.

I've only done limited testing, but so far, it appears to work seamlessly without causing any unintended consequences elsewhere.
