HTML
<h1 id="introText1">Hi, my name is <span>Liam Shalon.</span></h1>
CSS
#introText1 {
font-family: 'Source Sans Pro', sans-serif;
font-weight: 300;
left: 0;
line-height: 200px;
margin: auto;
margin-top: -110px;
position: absolute;
top: 50%;
width: 100%;
z-index: 1;
}
span {
font-weight: 900;
}

Please note that I intentionally increased the font-weight to emphasize the <span>
tag. A font-weight
difference of 100 wasn't very noticeable on the fiddle.
