Why Isn't My CSS :first-letter Selector Working on HTML from Microsoft Word?

CSS :first-Letter Selector Not Functioning

When dealing with HTML code extracted from Microsoft Word documents, styling issues can arise. In this case, we find that applying the :first-letter selector to the HTML generated from Word doesn't yield the desired effect.

The challenge lies in the fact that the :first-letter selector is only compatible with block elements. In the provided HTML, the title's first letter resides within an inline element, which is not a block element.

Solution 1: Apply :first-letter to a Block Element

A simple solution is to apply the :first-letter selector to the

element containing the title text instead of the .

p::first-letter {
    font-size: 500px;
}

Solution 2: Use a Block-Level Span

If modifying the original markup is not feasible, an alternative approach is to explicitly specify the display property as block for the element containing the first letter:

p b span::first-letter {
    font-size: 500px !important;
}
span {
    display: block;
}

Explanation

The :first-letter selector only affects the first letter of a block-level element, which is a container element that starts on a new line. Examples of block-level elements include paragraphs, headings, and table cells. Inline elements, such as , cannot be selected using this pseudo-element.

By modifying the element to be block-level, we effectively force it to behave like a block element, allowing the :first-letter selector to apply correctly.
