COloring links

L

Lewis

I used to know how to do this.

I have a link on a page that I need to color differently from the rest
of the links on the rest of the page, but I can't remember the syntax to
set the link, visited, and hover, and active colors within a style
declaration in the <a> tag.

I cannot edit the css file in this case to add a custom link color
section, which is what I would normally do.

I suppose I could do something like

<span style="color: red;"><a style="color: inherit" href="...">The
Link</a></span> but that 1) feels like a kludge 2) doesn't let me set
hover/visted/active colors.

Give the anchor a class or an id:

<a id=imaginary href="">whatever</a>

Add a <STYLE> element to the <HEAD> or your page:

<HEAD>
<STYLE type="text/css">
a#imaginary:visited { color: british-racing-green; }
a#imaginary:hover { color: sky-blue-pink; }
</STYLE>
</HEAD>

I do not have access to the head (I am editing a section of a site, and
I only have access to that little section of the HTML. I can't change
the page's CSS because I don't have access to it.

Use HTML5's scoped style:

<div class=scoped>
<style type="text/css" scoped>
.scoped a#imaginary:visited { color: british-racing-green; }
.scoped a#imaginary:hover { color: sky-blue-pink; }
</style>
<a id=imaginary href="">whatever</a>
</div>

The scoped attribure is not implemented on all browsers yet, but
with the additional class of a containing division, it should work.

Oh, that's clever. I know when last I had to do this it was far more
complicated than that.

Thanks!

"Not implemented on all browsers" is an understatement. It seems that
only Firefox, from version 21 or so, supports it:
http://caniuse.com/#feat=style-scoped
(And I would not bet much on the reliability of Firefox support,
especially since the whole scoped thing is experimental and debated.)

But the point here is that virtually all browsers actually let you put a
<style> element inside the <body> element, too, and act as if it were
inside the <head> element, even though this violates HTML
specifications. The proposed HTML5 rules would *restrict* the effect of
the style sheet.

It's really sufficient to use #imaginary in conjuction with the
pseudo-classes, since an id selector restricts the effect to a single
element.

Names like british-racing-green should not be used as dummies, since by
their form, they could be real color names, but they aren't.

Regarding the different states and the order of setting them, the LoVe -
HAte rule applies :)link, :visited, :hover, :active). On the other hand,
you don't need to set color on :hover and :active, if you prefer to use
other visual means, like background color or outline, for highlighting them.

Example (assuming you can wrap the link in a <div> element, which is
really needed here just to make the markup conform to proposed HTML5 rules):

<div>
<!-- the scoped attribute is here to keep HTML5 gods pleased. -->
<style scoped>
#imaginary:link { color: blue; }
#imaginary:visited { color: magenta; }
</style>
<a id=imaginary href="...">whatever</a>
</div>

Seems to work in Safari. Forgot to check Chrome.
<div>
<!-- the scoped attribute is here to keep HTML5 gods pleased. -->
<style scoped>
#imaginary:link { color: blue; }
#imaginary:visited { color: magenta; }
</style>
<a id=imaginary href="...">whatever</a>
</div>

Maybe that's why the example works in Safari.

That's a misunderstanding. If you visit page
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/style
on Safari, then the text
"This text should be black. If it is red your browser does not support
the scoped attribute."
appears in black.

Safari, like most browsers, does not support the scoped attribute in
<style> but simply ignores the attribute. As I explained earlier,
virtually all browsers support the <style> element within the <body>
element, so when you use <style scoped>, the style sheet works but not
as per HTML5 (as a scoped style sheet) but as a style sheet that applies
to the entire document. As discussed, you can still limit its effects to
content within a specific element, but you need to use that with
selectors, just as you would do in an external style sheet.
