Thanks for the good hint.
When I use the linear code from the website:
Summary
.color {
background: rgb(2,0,36);
background: -moz-linear-gradient(90deg, rgba(2,0,36,1) 0%, rgba(9,9,121,1) 10%, rgba(0,212,255,1) 50%);
background: -webkit-linear-gradient(90deg, rgba(2,0,36,1) 0%, rgba(9,9,121,1) 10%, rgba(0,212,255,1) 50%);
background: linear-gradient(90deg, rgba(2,0,36,1) 0%, rgba(9,9,121,1) 10%, rgba(0,212,255,1) 50%);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr="#020024",endColorstr="#00d4ff",GradientType=1);
}
This happens (only the background):
When I use this code, it works apperently, but users keep reporting me: they can’t see the text.
Summary
.color {
background: rgb(2,0,36);
background: linear-gradient(90deg, rgba(2,0,36,1) 0%, rgba(9,9,121,1) 10%, rgba(0,212,255,1) 50%);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
}
Between the image and the first text, there should a headline but it is invisible.
