How to style headings?

I would like to style my page headings on this site: http://california-apmp.org/wp/ like the ones here: http://www.apmp.org/?page=AccreditationProgram (the words “APMP PROFESSIONAL CERTIFICATION PROGRAM”). How can I do this?

this is how they did it with a DIV. (We can use their code because they are our parent organization). I don’t understand the url and how to get the image/svg thing. I could apply it all H4s for example or do DIVs if needed.

#SpTitleBar
{
background: #2c3a91; /* Old browsers */
/* IE9 SVG, needs conditional override of ‘filter’ to ‘none’ */
background: url(data:image/svg+xml;base64,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);

color: #fff;
float: left;

line-height: normal;
padding-left: 3%;
padding-right: 0;
text-transform: uppercase;
width: 100%;
padding-top: 15px;
padding-bottom: 15px;
}
