The fade out animation gradually transitions to complete blackness before fully fading out

I have a BLUE background on my webpage and I am trying to add a simple RED blinking circle. However, when the animation runs, it first turns black and then disappears.

body {
background: blue;
}
.blinker {
    width: 10px;
    height: 10px;
    background-color: red;
    position: absolute;
    border-radius: 50%;
    top: 5px;
    right: 10px;
    animation: blink 1s ease infinite;
}

@keyframes blink {
    from {
        opacity: 0;
    }
    to {
        opacity: 1;
    }
}
<span class="blinker"></span>

Answer №1

Uncertain if this meets your requirements, but I have incorporated a transition from black to red with opacity in the keyframes set against a background colour of blue. Please inform me if this aligns with your expectations.

 body {
background: blue;
}
.blinker {
    width: 10px;
    height: 10px;
    background-color: red;
    position: absolute;
    border-radius: 50%;
    top: 5px;
    right: 10px;
    animation: blink 1s ease infinite;
}

@keyframes blink {
    from{
      background-color: black;
        opacity: 0.7;
    }

    to {
      background-color: red;
        opacity: 1;
    }
}
<span class="blinker"></span>
