Question

link – I dont get it. I dont include any another font-face, I’ve reseted css, I’ve disabled headers bold and every browser is showing its as nice, thin letter, but Opera just show it bold.

Answer 1

It may be that opera bolds h1 elements by default. (Although you said you tried un-bolding it)

Try this first:

h1 {
    font-weight: normal;
}

if that doesn’t work, then maybe opera has a different definition of normal. In which case you should do something like this:

h1 {
    font-weight: lighter;
}

or if you wan’t even a little more control you could do something like:

h1 {
    font-weight: 100;
}
