### Extra space added for <codeblock> and <codeph>

Hi everyone,

I'm using "DITA Map PDF - based on HTML5 & CSS" in XML Author 21 to generate PDF documents, and I found sometimes an extra space is inserted for the <codeblock> and <codeph> tags.
• For the following code, and extra space is inserted at the beginning of the code block:

Code: Select all

by removing the following two lines:
<codeblock>&lt;extension module="org.jboss.as.jaxrs"/>
&lt;subsystem xmlns="urn:jboss:domain:jaxrs:1.0"/></codeblock>
• For the <codeph> tag, if a punctuation mark such as a comma or period is added right after it, an extra space is inserted before the punctuation mark. Like in the following code:

Code: Select all

...are also controlled in <codeph>customer.xml</codeph>. 
I'm not sure how to solve the problem. Can anyone give me a hand?

Thanks,
Michael

Hello Michael,

The transformation add a code inside the pre element. This is an inline element, that has some padding set from the built-in CSS. You should remove its padding:

Code: Select all

pre{
}
pre > code{
}
I fixed this in the default CSSs.

If you encounter more problems, please consider debugging the CSS as explained here:

Thank you for the feedback,

Hi Michael,

After Oxygen XML Support guided me to open the merged HTML in Chrome and inspect styles there, I have been using it quite heavily to debug PDF formatting issues. I imagine you'll find it quite useful too!

Don't forget to set the rendering mode to "print":

Hi,

We released Oxygen 21.1 and it should have this fix included.

### Re: Extra space added for <codeblock> and <codeph>

Tried Oxygen 21.1 and found that the issue was not fixed. In addition, my document title goes up and overlaps with the company icon. I think the "margin-top" property does not work properly in the following code:

Code: Select all

/* Document title on cover page */
*[class~="front-page/front-page-title"] {
display: block;
text-align: center;
margin-top: 34%;
font-size: 2.6em;
font-weight: bold;
line-height: 105%;
}

Guess I'd better revert to Oxygen 21 and fix the issue manually.

Hi Dan,

I tried your code and the issue was basically fixed. However, for the <codeph> before a punctuation mark, such as a comma or a period, an extra space is still inserted before the punctuation mark. I think it is not a padding issue because for <codeph> between two words, everything is okay. And I checked the generated HTML and found nothing was inserted there.

Do you have any idea how to fix that issue?

Cheers,
Michael

### Re: Extra space added for <codeblock> and <codeph>

Hello Michael,

I tried to use the DITA sample:

Code: Select all

[Oxygen Install Dir]\samples\dita\it-book\taskbook.ditamap
and the standard HTML transformation using the 'ashes' template but I cannot reproduce the problem.

Please try to use a standard publishing template (the first tab in the transformation scenario), with no customization.
Open the FO file from the output folder and search for the codeph text. Check if there is a space in the text. You can take a look also into the .style.xml file.

If you do not detect the cause, please send us more details, like the full DITA fragment, and the FO fragment.

Many regards,
Dan

### Re: Extra space added for <codeblock> and <codeph>

Hi Dan,

It is not that obvious in the generated PDF. If you copy the text into a text editor, you will see an extra space before the punctuation mark. I tested again and found that there is no extra space in the .fo file. Guess the issue might be related to the process that transforms the .fo and .html files into a single PDF.

My environment is as follows:
• Version: Oxygen Author 21
• Transformation Scenario: DITA Map PDF - based on HTML5 & CSS
• Template: Ashes [tiles]
My test DITA file is as follows:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE concept PUBLIC "-//OASIS//DTD DITA Concept//EN" "concept.dtd">
<concept id="test">
<title>test</title>
<shortdesc></shortdesc>
<conbody>
<p>This is a test for <codeph>codeph</codeph>.</p>
</conbody>
</concept>

My test DITAMAP file is as follows:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE map PUBLIC "-//OASIS//DTD DITA Map//EN" "map.dtd">
<map>
<title>test map</title>
<topicref href="test.dita"/>
</map>

The relevant code in the generated .fo file is as follows:

Code: Select all

<fo:block-container margin-bottom="0.5em" margin-left="0" margin-right="0" margin-top="1em"><fo:block end-indent="0" start-indent="0">This is a test for <fo:inline font-family="monospace" font-size="smaller" role="Code" padding-bottom="2px" padding-left="4px" padding-right="4px" padding-top="2px">codeph</fo:inline>.</fo:block></fo:block-container>

If I copy the text from the generated PDF and paste into a text editor, the result is as follows:

Code: Select all

This is a test for codeph .

Note there is a space between the letter h and the period.

Cheers,
Michael

### Re: Extra space added for <codeblock> and <codeph>

Thank you for the details!

The problem is caused by the

Code: Select all

padding-right="4px"
. This looks like either our fix from the built-in CSS is not working, or you have such padding set in the customization CSS.

Please open the merged HTML file in a browser (Chrome for instance), and using the developer tools inspect the element containing the codeph text. You will see what rules are applying and from what CSS.

Many regards,
Dan

### Re: Extra space added for <codeblock> and <codeph>

You are quite right, Dan. I added the following code into my customization css and the problem was solved:

Code: Select all

code{
}

Thanks again!

Michael
