How can I make the blinking cursor disappear after 3 seconds at the end of the animation?

Issue

I have this HTML

      <div class=typewriter>
        <h1>Lorem Ipsum</h1>
      </div>

and this CSS

.typewriter {
    display: inline-block;
}

.typewriter h1 {
    overflow: hidden;
    border-right: .15em solid black;
    white-space: nowrap;
    margin: 0 auto;
    letter-spacing: .15em;
    animation:
        typing 3.5s steps(30, end),
        blink .75s step-end 0s infinite;
}

@keyframes typing {
    from {
        width: 0;
    }

    to {
        width: 100%;
    }
}

@keyframes blink {

    0%,
    100% {
        border-color: black;
    }

    50% {
        border-color: transparent;
    }
}

The animation is almost perfect, but I need the cursor to disappear after 3 seconds at the end of animation.

How can I do it? Also, there's anything I could improve?

I look at other questions like this one, but it didn't solve the problem.

Solution

Simply add another keyframe.

.typewriter {
  display: inline-block;
}

.typewriter h1 {
  overflow: hidden;
  border-right: .15em solid black;
  white-space: nowrap;
  margin: 0 auto;
  letter-spacing: .15em;
  animation:
    typing 3.5s steps(30, end),
    blink .75s step-end 0s infinite,
    end 3s 3.5s forwards;
}

@keyframes typing {
  from {
    width: 0;
  }

  to {
    width: 100%;
  }
}

@keyframes blink {

  0%,
  100% {
    border-color: black;
  }

  50% {
    border-color: transparent;
  }
}

@keyframes end {
  to {
    border-right: 0 solid transparent;
  }
}

<div class="typewriter">
  <h1>Lorem Ipsum</h1>
</div>

In this example, I have added end. After 3 seconds (feel free to change it), the color of border-right should be transparent.
