Can Someone Help Breakdown this String?

I'm having some trouble understanding how this string was put together. What's making it confusing for me is the use of quotations marks and the blend of JS, HTML and CSS.

html += '<div style="background-color:' + rgbColor + '"></div>';

Here's a breakdown of the statement into 3 parts:

var backgroundColor = "background-color:"  + rgbColor; // Sets the 'background-color' property with 'rgbColor' value
var divHTML = "<div style=" + backgroundColor + "></div>"; // Builds the <div> tag with 'style' set to the above 'builtbackgroundColor'
html += divHTML; // Appends the built '<div>...</div>' string to 'html'
