When I use the following code:
<style>
h1 {
height: 200px;
background: linear-gradient(red, green, blue);
} </style>
I get the standard color spectrum with horizontal lines. Now, I want to change it so that the lines are vertical. I've tried this:
<style>
h1 {
height: 200px;
background: linear-gradient(left, red, green, blue);
} </style>
but unfortunately, that solution doesn't work.
