gouri - As lucy said, "Remembering My Summer Vacation" sounds like a subheader, so you might use
<h3>Remembering My Summer Vacation</h3>
and define the specific attributes of size, boldness, etc of <h3> in the header.
I suggested using <p> instead of <h3> only because I prefer not to put one header directly under another header. Even if you use <p>, you can still center it as follows:
<p style="text-align: center; font-size: 110%; font-weight: 500">Remembering My Summer Vacation</p>
As for links, I like to make the anchor text larger and bolder so that it is easier to click on. I also like to center an isolated one-line link. The simplest way to do this is to use an <h> tag, such as
<h4>The Link to the Next Page</h4>
where you define the attributes of <h4> in the header.
Occasionally I've read that you shouldn't put links inside <h> tags, but I've done it many times, and it validates at W3C.
