Using a heading (like h2
) for this sentence would create a wrong outline. Everything that follows would be in scope of this "heading", which is likely not what you intend. If it would be content appropriate for a heading, it should be part of the first heading (h1
).
(It’s not appropriate for a heading because it doesn’t seem to describe the content that follows in any other way than what the parent heading says; it’s just giving more context to it.)
Using the em
element for the whole sentence would be wrong, because it doesn’t at all seem to require "emphasis" which "changes the meaning of the sentence". You could argue if the word "vital" might be appropriate for em
, but that’s something only the authors of that sentence would have to decide (i.e., how they meant it).
The p
element is the obvious and appropriate choice here.
If you consider this sentence to be part of the introduction (I think it is), you could use a header
that contains the h1
as well as this p
:
<article>
<header>
<h1>Marketing Bachelor’s Degree</h1>
<p>Attain the marketing skills … </p>
</header>
<p>Fueled by …</p>
</article>
If you think it’s something like the lede (or lead paragraph) of that article, you could also use the b
element for this sentence (in addition to p
and possibly the header
):
The b
element represents a span of text to which attention is being drawn for utilitarian purposes without conveying any extra importance and with no implication of an alternate voice or mood, such as […] an article lede.
<p>
... reserve headers for short one liner sentences or a few keywords to outline what the below text is about. Also just to point out<em>
can be used within p or h to emphasized a word within.<blockquote>
when citing external sources, and even then you should use<p>
within blockqoute, if the sentences is more than a short sentence. It is also recommended to use headers within blockquote if the source does so, or if it makes sense to do so.
