i want to change my font-family of a <span>
tag into Opensans SemiboldItalic font. but i dont know how?
#footer .container span {
font-family: 'Open Sans Semibold';
}
You have to use font-weight and font-style.
font-family: 'Open Sans', Arial, sans-serif;
font-weight: 600;
font-style: italic;
Make sure you are calling the semi-bold italic font weight (600) as well:
<link href='//fonts.googleapis.com/css?family=Open+Sans:600italic' rel='stylesheet' type='text/css'>
