<p>Hi Frank,</p>
<p><br>
</p>
<p>There are two distinct aspects to this:</p>
<p><br>
</p>
<p>1) Installing your framework in Oxygen and editing a DITA topic
in the Author mode using your custom framework's CSS. I tested and
on my side Oxygen reports no error when opening and editing a DITA
topic with your framework. So I cannot reproduce this problem you
reported:</p>
<p><br>
</p>
<p>
<blockquote type="cite">This is annoying because the "Results"
window keeps popping up whenever I save a dita file.</blockquote>
2) Opening your "custom.css" in Oxygen and validating it. Here
indeed some errors are reported.</p>
<p><br>
</p>
<p>2.1) <br>
</p>
<p><br>
</p>
<p>
<blockquote type="cite">Unknown pseudo-element or pseudo-class
“:no-tags”</blockquote>
You can avoid this error by prefixing the custom pseudo class with
"-oxy-", something like ":root:-oxy-no-tags".</p>
<p>Also make sure you prefix the pseudo class value also in the
oxy_action.</p>
<p><br>
</p>
<p>2.2)</p>
<p><br>
</p>
<p>
<blockquote type="cite">“-2em” negative values are not allowed :</blockquote>
Such errors are reported by the W3C CSS validator, the CSS is
considered invalid according to the CSS standard. We do not have
settings to filter out errors reported by the CSS validator.</p>
<p><br>
</p>
<p>2.3)</p>
<p><br>
</p>
<p>
<blockquote type="cite">Property “margin-inline-start” doesn't
exist : 0</blockquote>
Again this property does not see to be defined in the CSS3
standard and is reported as such by the W3C CSS validator. We do
not have a way to inhibit this.</p>
<p>Oxygen's CSS engine used to render DITA topics in the Author mode
does not support this "margin-inline-start" property or use it in
any way. But some browsers seem to support it.<br>
</p>
<p><br>
</p>
<p>Regards,</p>
<p>Radu</p>

<p>Hi list,</p>
<p><br>
</p>
<p>I keep getting the following CSS validation errors for my
"custom.css" file in oXygen V25: </p>
<ul>
<li>Unknown pseudo-element or pseudo-class “:no-tags”</li>
<li>Negative values are not allowed: -0.5em <i>(padding)</i></li>
<li>Property “margin-inline-start” doesn't exist : 0</li>
</ul>
<p>This is annoying because the "Results" window keeps popping up
whenever I save a dita file.</p>
<p><br>
</p>
<p>How can I tell oXygen to ignore these
elements/properties/values?</p>
<p>I can't find the required settings under "Options >
Preferences > CSS Validator".</p>
