Hi
How do I increase the size of my text in my header
This is what I see in the layout css I amended h1 but it didnt seem to make any difference
body {
margin:0;
padding:0;
font-family:Tahoma,Verdana, Arial, Helvetica, sans-serif;
font-size:100.01%;
position:relative;
z-index:90;
}
h1,h2,h3,h4 {
font-weight:normal;
}
h3,h4,h5,h6 {
margin-bottom:0;
}
h3+p,h4+p,h5+p,h6+p {
margin-top:0;
}
h1 {
font-size:11.6em;
letter-spacing:.02em;
}
h2 {
font-size:1.6em;
letter-spacing:.02em;
}
h3 {
font-size:1.4em;
letter-spacing:.01em;
}
h4 {
font-size:1.2em;
letter-spacing:.01em;
}
h5,h6 {
font-size:1em;
letter-spacing:.01em;
}
img {
border:none;
}
dt {
font-weight:bold;
margin-top:10px;
