<p>Your website probably has a color-scheme.
|
|
<span style="color:#090; background:#FFF;">Green on white</span>,
|
|
<span style="color:#A0F; background:#FF0;">purple on yellow</span>,
|
|
whatever. When you give users the ability to style their content, you may
|
|
want them to keep in line with your styling. If you're website is all
|
|
about light colors, you don't want a user to come in and vandalize your
|
|
page with a deep maroon.</p>
|
|
|
|
<p>This is an extremely silly feature proposal, but I'm writing it down anyway.</p>
|
|
|
|
<p>What if the user could constrain the colors specified in inline styles? You
|
|
are only allowed to use these shades of dark green for text and these shades
|
|
of light yellow for the background. At the very least, you could ensure
|
|
that we did not have pale yellow on white text.</p>
|
|
|
|
<h2>Implementation issues</h2>
|
|
|
|
<ol>
|
|
<li>Requires the color attribute definition to know, currently, what the text
|
|
and background colors are. This becomes difficult when classes are thrown
|
|
into the mix.</li>
|
|
<li>The user still has to define the permissible colors, how does one do
|
|
something like that?</li>
|
|
</ol>
