<html><head><style>h1{
font-size:22px;
color: red;
padding:10px;
}</style></head><body><h1>Welcome to the Lancashire Digital website</h1></body></html>
What's the best way?
Always use external CSS* (where possible)
<html><head><linkrel="stylesheet"href="css/main.css"></head><body><!-- you style elements in here via CSS --></body></html>
