Focusing on specific parents to target the same children using CSS and jQuery selectors

Is there a more efficient way to target specific children of select parents in CSS without excessive repetition and lengthening the selector?

For instance, if I want to style the first-child paragraph within certain divs.

The current CSS method:

.funny > p:first-child, .sad > p:first-child {
 color: red
}

Sample markup:

<div class="funny">
  <p>This is red</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
</div>

<div class="wildcrazy">
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
</div>

<div class="sad">
  <p>This is red</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
</div>

In reality, there could be various other first paragraphs in different divs that need styling, while some divs should not be targeted.

My inquiry is whether it's possible to declare the child element once alongside all its parent elements. Could the syntax look something like this?

.funny, .sad, .another_div_class0, .another_div_class1, .another_div_class2, .another_div_class3 > p:first-child

Instead of repeating the selectors for each parent, such as:

.funny p:first, .sad p:first-child, .another_div_class0 p:first-child, .another_div_class1 p:first-child, .another_div_class2 p:first-child, .another_div_class3 p:first-child

Answer №1

When using jQuery, the following selection:

.funny, .sad, .another_div_class0, .another_div_class1, .another_div_class2, .another_div_class3 > p:first

can be rewritten as:

$('.funny, .sad, .another_div_class0, .another_div_class1, .another_div_class2, .another_div_class3').children('p:first')

Answer №2

I'm not sure about CSS, but using jquery could be a solution. Simply gather all your parent classes in a selector and specify that you only want to target the paragraphs that are children of these selectors:

$('.funny, .sad, .another_div_class0, .another_div_class1, .another_div_class2, .another_div_class3').each( function() {
    $('p:first-child', this).css(Do whatever you want);
});

Answer №3

why not consider adding an additional class to the div elements you wish to target, following this approach?

<div class="funny selectthis">
  <p>This is red</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
</div>

<div class="wildcrazy">
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
</div>

<div class="sad selectthis">
  <p>This is red</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
  <p>This is whatever</p>
</div>

Afterward, utilize the provided code snippet:

$('.selectthis').find('p:first').css('color','red');​

$('.amusing, .unhappy, .additional_div_class0, .additional_div_class1, .additional_div_class2, .additional_div_class3').locate('p:first')
