How to select multiple elements using CSS

I have the following markup:

<div class="c1">
  <div class="c2">
    <div class="c3">
      <input>
      <textarea></textarea>
    </div>

    <input>
    <textarea></textarea>
  </div>
</div>

I want to match the input and textarea elements from the div.c3 with only one CSS rule. I'm using

div.c1 .c2 .c3 input,textarea { border: 1px solid #f00; }

but this matches all textareas, not only the one cotnained in the c3 div.

Is this possible, or must I write separate CSS selectors for each element?

开发者_StackOverflowLook at http://jsfiddle.net/Bp3qn/1/ for the live example.

I updated http://jsfiddle.net/Bp3qn/3/

I only need the input and textarea contained in the c1->c2->c3 containers to be highlighted, not other combinations.

You don't need the other elements in the selector, unless you only want to match .c3 if it is within div.c1 .c2:

.c3 input,
.c3 textarea {
    /* that's it! */
}

If you do (per your edit), use this:

div.c1 .c2 .c3 input,
div.c1 .c2 .c3 textarea{
    border: 1px solid #f00;
}

after edit: thats what i'm trying to avoid (my real stylesheet is a lot more complex and css rules are longer, and its getting hard to read)

In that case, to make things easier just add another class to that .c3 like this:

<div class="c3 special">

.c3.special input,
.c3.special textarea{
    border: 1px solid #f00;
}

Demo: http://jsfiddle.net/wesley_murch/Bp3qn/7/

If you MUST have the selector as small as possible and there are no other children of .c3.special, just use the star selector (almost never recommended):

.c3.special * {border: 1px solid #f00;}

---

div.c1 .c2 .c3 input,.c3 textarea { border: 1px solid #f00; }

I know it's an old topic but I wanted to add some points on this because I just ended up here while trying to apply the same king of logic. And thanks to this question, I know now that we should reconsider that logic a bit.

First, the upvoted answer does solve the question but I don't understand why the use of .c1 .c2 classes in the CSS.

As @Wesley Murch first wrote, that should be enough:

.c3 input,.c3 textarea { /* that's it! */ }

It's also ok to specify a bit more with:

div.c3 input,
div.c3 textarea {
    border: 1px solid #f00;
}

which is already the shorthand for:

div.c3 > input,
div.c3 > textarea {
    border: 1px solid #f00;
}

But, IMO, unless you really have no control of what's inside your div, you should simplify everything by just adding one more class in your HTML and then you'll also end up with only one rule which will be even a bit easier to read:

HTML update with one more class special-border-color for exemple:

<div class="c1">
    <div class="c2">
        <div class="c3">
            <input class="special-border-color">
            <textarea class="special-border-color"></textarea>
        </div>
            
        <input>
        <textarea></textarea>
    </div>
</div>

CSS simple rule:

.special-border-color {
    border: 1px solid #f00;
}
