Something like this should work;

HTML: Select all

<h1><span>F</span>OR<span>U</span>MS

And for your CSS;

Code: Select all

h1 {
/*Styles for heading*/
}
h1 span {
color: /*Different colour*/
}

You can also use the CSS pseudo-element :first-letter to style the first letter of an element, without any additional HTML markup.
