Large distance between two adjacent <h...> elements - html

Question

I have noticed when I have a <h2> tag directly below an <h1> tag there is a large gap between the two. No padding or margin is set and I've normalised the css using normalize.css. Why does this gap exist?
Fiddle here: fiddle
Here is a screen shot:
html (normalize.css is active on this html)
<div class="header">
<div class="wrapper">
<h1>Portfolio of...</h1>
<h2>Jing Xue</h2>
</div>
</div>
css
.wrapper {
width: 940px;
margin: 0 auto 0 auto;
}
/* header ------------------------------------------------------------------ */
.header {
text-align: center;
padding: 40px 0 0 0;
margin-bottom: 40px;
}
.header h1 {
font-family: 'Delius Swash Caps', cursive;
font-size: 250%;
color: rgb(200,50,50);
/* margin-bottom: -50px; */
}
.header h2 {
font-family: 'Playfair Display SC', serif;
font-size: 450%;
color: rgb(59,67,68);
}
Further Question
For what ever the reason for this big gap between "portfolio of..." and "Jing Xue", is the correct way to reduce the gap to give a negative top/bottom margin on the corresponding <h..>?

Answer 1

h1 through h4 tags have a default margin. You need to remove that margin in your CSS.
.header h1 {
font-family: 'Delius Swash Caps', cursive;
font-size: 250%;
color: rgb(200,50,50);
margin:0;
}
.header h2 {
font-family: 'Playfair Display SC', serif;
font-size: 450%;
color: rgb(59,67,68);
margin:0;
}

Answer 2

This is normal behaviour for these elements..
You forgot to take the default margin-top off of your h2 element. Simply add margin-top:0px; to your h2 class.
Here is a working jsFiddle.
Your class should now look like below:
.header h2 {
font-family: 'Playfair Display SC', serif;
font-size: 450%;
color: rgb(59,67,68);
margin-top:0px;
}
