For simplicity, you can do as already doing

document.write("<b>"+myCar.name+"</b><br>"); //bold style
document.write("<p>"+myCar.doi+"</p>"); //pata graph
here you can add inline css..
Or
Create a tag, by document's createChild or append child methods and then you can add content and style by (obj).style={.. }
Or by
jquery's
$("tag").css ( {"add styling here "} )
May be there better methods idk...
