How to change first letter of every posts in Wordpress?

Question

I am trying to customize every single post of first-paragraph starts with first-letter only, bold and larger fonts. But it does not appear on first-letter of the first paragraph. Instead, it appears on every paragraph rather than the first-paragraph.

This is for a Wordpress template. In the past I've tried using the property first-child. However, it didn't seem to be working.

p::first-letter {
  font-size:300%;
  color:#00aff2;
  font-style:bold;
  border: 2px solid #00aff2;
  margin:0 5px 3px 0;
  padding: 3px;
}

Answer 1

You can use :first-child to apply ::first-letter to the first paragraph only.

p:first-child::first-letter {
    font-size:300%;
    color:#00aff2;
    font-style:bold;
    border: 2px solid #00aff2;
    margin:0 5px 3px 0;
    padding: 3px;
}
