Background color not showing in print preview

2019-01-01 08:07发布

I am trying to print a page. In that page I have given a table a background color. When I view the print preview in chrome its not taking on the background color property...

So I tried this property:

-webkit-print-color-adjust: exact; 

but still its not showing the color.

http://jsfiddle.net/TbrtD/

.vendorListHeading {
  background-color: #1a4567;
  color: white;
  -webkit-print-color-adjust: exact; 
}


<div class="bs-docs-example" id="soTable" style="padding-top: 10px;">
  <table class="table" style="margin-bottom: 0px;">
    <thead>
      <tr class="vendorListHeading" style="">
        <th>Date</th>
        <th>PO Number</th>
        <th>Term</th>
        <th>Tax</th>
        <th>Quote Number</th>
        <th>Status</th>
        <th>Account Mgr</th>
        <th>Shipping Method</th>
        <th>Shipping Account</th>
        <th style="width: 184px;">QA</th>
        <th id="referenceSO">Reference</th>
        <th id="referenceSO" style="width: 146px;">End-User Name</th>
        <th id="referenceSO" style="width: 118px;">End-User's PO</th>
        <th id="referenceSO" style="width: 148px;">Tracking Number</th>
      </tr>
    </thead>
    <tbody>
      <tr class="">
        <td>22</td>
        <td>20130000</td>
        <td>Jim B.</td>
        <td>22</td>
        <td>510 xxx yyyy</td>
        <td>zznn@abc.co</td>
        <td>PDF</td>
        <td>12/23/2012</td>
        <td>Approved</td>
        <td>PDF</td>
        <td id="referenceSO">12/23/2012</td>
        <td id="referenceSO">Approved</td>
      </tr>
    </tbody>
  </table>
</div>

If you download Bootstrap without the "Print media styles" option, you will not have this problem and do not have to remove the "@media print" code manually in your bootstrap.css file.

I double load my external css source file and change the media="screen" to media="print" and all the borders for my table were shown

Try this :

<link rel="stylesheet" media="print" href="bootstrap.css" />

<link rel="stylesheet" media="screen" href="bootstrap.css" />

if you are using Bootstrap.just use this code in your custom css file. Bootstrap removes all your colors in print preview.

@media print{
  .box-text {

    font-size: 27px !important; 
    color: blue !important;
    -webkit-print-color-adjust: exact !important;
  }
}

The Chrome CSS property -webkit-print-color-adjust: exact; works appropriately.

However, making sure you have the correct CSS for printing can often be tricky. Several things can be done to avoid the difficulties you are having. First, separate all your print CSS from your screen CSS. This is done via the @media print and @media screen.

Often times just setting up some extra @media print CSS is not enough because you still have all your other CSS included when printing as well. In these cases you just need to be aware of CSS specificity as the print rules don't automatically win against non-print CSS rules.

In your case, the -webkit-print-color-adjust: exact is working. However, your background-color and color definitions are being beaten out by other CSS with higher specificity.

While I do not endorse using !important in nearly any circumstance, the following definitions work properly and expose the problem:

@media print {
    tr.vendorListHeading {
        background-color: #1a4567 !important;
        -webkit-print-color-adjust: exact; 
    }
}

@media print {
    .vendorListHeading th {
        color: white !important;
    }
}

Here is the fiddle (and embedded for ease of print previewing).

If you are using bootstrap or any other 3rd party CSS, make sure you specify the media screen only on it, so you have the control of the print media type in your own CSS files:

<link rel="stylesheet" media="screen" href="">

FOR THOSE USING BOOTSTRAP.CSS, this is the fix!

I have tried all the solutions and they weren't working... until I discovered that bootstrap.css had a super annoying @media print that resets all your colors, background-colors, shadows, etc...

@media print{*,:after,:before{color:#000!important;text-shadow:none!important;background:0 0!important;-webkit-box-shadow:none!important;box-shadow:none!important}

So either remove this section from bootstrap.css (or bootstrap.min.css)

Or override these values in the css of the page you want to print in your own @media print

@media print {
  body { 
    -webkit-print-color-adjust: exact; 
  }
  .customClass{
     //customCss + !important;
  }
  //more of your custom css
}
