Modify the color of the H1 tag exclusively within specific classes

Struggling with a formatting issue here. I'm looking to customize the colors of h1, h2, h3... when they are inside specific classes. It's mostly working as intended, however, the problem arises when the headings outside of those classes don't always revert back to their original color. Any suggestions on how to fix this? Here's the snippet of my code:

CSS:

.white_rectangle,.extras h1,h2,h3,h4,h5,h6{
    color: navy;
}

I want all h1, h2, etc. inside these classes (white_rectangle and extras) to have navy color. For any other instances, I've set the following:

h1, h2, h3, h4, h5, h6 { color: red; font-weight: normal }

HTML:

<h1>Before</h1>
<h3>Before</h3>

<table class='extras'>
    <tr><td><h1>Text Inside Class</h1></td></tr>
</table>

<h1>After</h1>
<h2>After</h2>

Fiddle: http://jsfiddle.net/y5hg8ke5/

The goal is for the "Before" and "After" text to be in red, but it doesn't seem to be functioning correctly.

Answer №1

.navy_text,
.additional h1,
.additional h2,
.additional h3,
.additional h4,
.additional h5,
.additional h6 {
    color: navy;
}

Answer №2

Utilize the :any pseudo-class.

.white_rectangle, .extras :any(h1, h2, h3, h4, h5, h6) {
    color: navy;
}

Nonetheless, when implementing this, it is necessary to also use vendor-prefixed versions such as -moz-any and -webkit-any, which may not significantly reduce your typing effort. Avoid combining them in a single rule like so:

.white_rectangle, .extras :-moz-any(h1, h2...), .extras :-webkit-any(h1, h2...)

This is because other browsers will disregard the entire rule due to the presence of an unrecognized vendor-prefixed pseudo-class. Instead, specify them individually:

.white_rectangle { color: navy: }
.extras :-webkit-any(h1, h2, h3, h4, h5, h6) { color: navy; }
.extras :   -moz-any(h1, h2, h3, h4, h5, h6) { color: navy; }

Unfortunately, support for IE and Opera is lacking. Check out https://developer.mozilla.org/en/docs/Web/CSS/:any. Note from that page (thanks @HashemQolami):

Note : This pseudo-class is in progress to be standardized in CSS Selectors Level 4 under the name :matches(). It is likely that the syntax and name of :-vendor-any() will be changed to reflect it in the near future.

Answer №3

Remember to add the primary "h1,h2..." to every selector (.additional).

For example:

.blue_square,.additional h1,.additional h2,.additional h3,.additional h4,.additional h5,.additional h6 { 
   color: teal; 
}

Answer №4

Check out this code snippet

I made some CSS adjustments as shown below CSS Modifications

h1,h2,h3,h4,h5,h6 { color: red; font-weight: normal }

.white_rectangle,.extras h1,.extras h2,.extras h3,.extras h4,.extras h5{
    color: navy;
}

In this update, I have specifically targeted headings (h1, h2, h3, h4, h5, h6) within the .extras class.

Answer №5

The reason for this behavior is due to the fact that you are applying the style color: navy to all headings regardless of whether they are nested within the .extras class or not.

A more accurate approach would be:

.extras h1, .extras h2, .extras h3, .extras h4, .extras h5, .extras h6 {
    color: navy; 
}
