Your notebooks should have a fancy title... use HTML for that! just copy-paste this and render it as html in your Jupyter Notebook:
<div style="font-variant: small-caps;
font-weight: normal;
font-size: 30px;
text-align: center;
padding: 15px;
margin: 10px;">
This is a cool title
</div>
<div style="font-variant: small-caps;
font-weight: normal;
font-size: 20px;
text-align: center;
padding: 15px;">
and this is a subtitle
</div>
<div style=" float:right;
font-size: 12px;
line-height: 12px;
padding: 10px 15px 8px;">
