I don’t understand the use of span in this challenge. It’s supposed to somehow effect the width I think? All it’s doing in this case is changing the color of the text to text-danger, which I could have done without using span.
<span> is useful for styling only certain parts of text, without changing or introducing any semantics. It’s like a <div>, but whereas <div>s are block elements, <span>s are inline elements.
Also, challenges are not numbered. The 74 is your brownie points (sort of like your fCC score) and completing challenges isn’t the only way to get brownies.
basically kevcomedia summed it up; the effects one would normally apply with a span element could be achieved by using inline styling in the HTML code itself, but it’s cleaner code to do such inline styling by using the span.
