gradient background transition code example

Example 1: transition background gradient

In CSS, you can't transition a background gradient. It jumps from one gradient to the other immediately, with no smooth transition between the two. He documents a clever tactic of positioning a pseudo element covering the element with a different background and transitioning the opacity of that pseudo element.

Example 2: html css background linear-gradient

background: linear-gradient(#333, #333 50%, #eee 100%);
\\code for a basic gradient background
   #grad {
  background-image: linear-gradient(red, yellow);
}
