First-letter prints incorrectly in Chrome #21771

zam6ak · 2017-01-18T15:07:49Z

When using display headings and trying to print (Ctrl+P) the first letter of the heading breaks layout.
Tested on Chrome v55

Here is sample HTML code

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <title>Print Test</title>

    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js">
</head>

<body>

    <div class="container-fluid">
        
        <div class="row">
            <div class="col">
                <h1 class="display-4">This heading fails to print</h1>
                <p class="lead">This heading fails to print correctly.</p>
            </div>
        </div>

        <div class="row">
            <div class="col">
                <h1 class="display-1">Display 1</h1>
                <h1 class="display-2">Display 2</h1>
                <h1 class="display-3">Display 3</h1>
                <h1 class="display-4">Display 4</h1>
            </div>
        </div>

        <div class="row">
            <div class="col">
                <h1 id="h1-heading">h1 heading</h1>
                <p>Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>

                <h2 id="h2-heading">h2 heading</h2>
                <p>Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>

                <h3 id="h3-heading">h3 heading</h3>
                <p>Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>

                <h4 id="h4-heading">h4 heading</h4>
                <p>Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>

                <h5 id="h5-heading">h5 heading</h5>
                <p>Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>

                <h6 id="h6-heading">h6 heading</h6>
                <p>Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>
            </div>
        </div>

    </div>

Here is how browser renders the page vs what the print preview looks like.
Please note that changing from "Save as PDF" to actual printer has no effect....

perttumyry · 2017-02-09T08:36:16Z

As a temporary solution before this is fixed, this seemed to give proper print results for h1.

h1::first-letter {
    margin-top: 0;
}

nataniel · 2017-03-31T18:15:13Z

It's not display headings, it's every Hx.

This is all fine:

<h1>Test</h1>
<h2>Test</h2>
<h3>Test</h3>
<h4>Test</h4>

All of those display with first letter problem:

<div class="row">
    <div class="col-6">
        <h1>Test</h1>
    </div>
    <div class="col-6">
        <h2>Test</h2>
    </div>
    <div class="col-6">
        <h3>Test</h3>
    </div>
    <div class="col-6">
        <h4>Test</h4>
    </div>
</div>

Tested with v4.0.0-alpha.6

from #22308 @bschlosser

This doesn't seem to be font related. I tried with sans-serif, serif, and Arial on macOS and they all exhibit the same up and down shift.

You can make the issue appear using the Dev Tools

(Three dot menu)->More Tools->Rendering set Emulate CSS Media to print

Inspect the h2 element for "Easy to get Started"

In the Styles pane, disable and reenable the font-size property on the h2 class

You should then see the problem.

To temporarily "fix it", scroll down in the Styles pane and find the
@media print *, ::after, ::before, blockquote::first-letter, blockquote::first-line, div::first-letter, div::first-line, li::first-letter, li::first-line, p::first-letter, p::first-line selector and disable all of the text and box shadow properties, it looks correct, both on screen and printed.

More specifically it looks like the div::first-letter selector in combination with the text and box shadow properties are the key.

Issue can also be observed in code blocks in the docs (where the opening "<" is too high up). Possibly related, some lines get cut off between pages when printing.

patrickhlauke · 2017-04-19T09:01:53Z

Possibly also related #22425

Seems to be okay in 4.0.0 alpha 5 but seeing a similar issue with alpha 6

vassyz · 2017-05-04T15:59:29Z

Also in inputs:

Wardrop · 2017-05-09T23:46:04Z

I see this also in the latest Alpha. Working around it by disabling print styles $enable-print-styles: false;

nicrider · 2017-05-23T19:29:01Z

I see this as well in alpha 6. Overriding the ::first-letter in the header like this seemed to work around the issue:

<style media="print">
::first-letter{
  margin: 0;
  padding: 0;
}
</style>

grantzau · 2017-05-28T10:29:52Z

Same problem for me for text within <sup> element. I cannot fix it by overwriting CSS with any of the suggested solutions.

It seems that the problem occurs already when the text-shadow and box-shadow properties are set in the first place (by the bootstrap print stylesheet). So, no matter what I set them to, the problem persists.

The only way I can fix it is by removing the CSS by setting $enable-print-styles: false; (or I could edit _print.scss and remove the text-shadow and box-shadow declarations).

nafg · 2017-07-11T01:49:02Z

Can someone explain why/how this happens?

patrickhlauke · 2017-07-11T09:38:42Z

Short explanation: it's a Chrome bug. I actually found the issue in the Chrome bug tracker, but as I commented on it the issue was moved/locked...in any case, it was https://bugs.chromium.org/p/chromium/issues/detail?id=739800 (if anybody else has more joy seeing it with their credentials)

Bootstrap itself doesn't use any `::first-letter` or `::first-line` styles. These selectors also cause(d) problems in IE11 (see h5bp/html5-boilerplate#1799) and currently cause a nasty rendering bug in Chrome where the first letter is vertically shifted (see #21771) As h5bp has now removed these as well, no need to keep and comment them out. See h5bp/html5-boilerplate#1961 / h5bp/html5-boilerplate#1962

@patrickhlauke FWIW I can view the bug without signing in. Thanks for the link. :)

@nafg yes the bug was reopened to the public after a friend at Google queried it being restricted https://bugs.chromium.org/p/chromium/issues/detail?id=739800#c6
