Why is the <sub> and <sup> not supporting the ::first-letter CSS pseudo-element? Any solutions?
p:first-letter,
sub:first-letter,
sup:first-letter {
color: red;
font-weight: bold;
}<p>This text contains <sub>subscript</sub> text.</p>
<p>This text contains <sup>superscript</sup> text.</p>According to @temani-afif, this issue was addressed on html - CSS :first-letter not working - Stack Overflow, but it does not specifically mention <sub> and <sup> tags.
The
::first-letterCSS pseudo-element targets the initial letter of the first line within a block-level element, but only if there is no preceding content. -- ::first-letter - CSS: Cascading Style Sheets | MDN
The <sub> and <sup> tags are not originally classified as block-level elements, yet utilizing the CSS display Property with an inline-block setting can adjust this behavior.
p:first-letter,
sub:first-letter,
sup:first-letter {
color: red;
font-weight: bold;
}
sub,
sup {
display: inline-block;
}<p>This text contains <sub>subscript</sub> text.</p>
<p>This text contains <sup>superscript</sup> text.</p>I am attempting to pass JSON results from Python to HTML using AJAX in Node.js.
