A Valentine's Day Message Page for Programmers

In
A small Valentine's Day page that reveals a personal message with a typing effect.

A hand-made web page is a simple way to combine programming with a personal Valentine’s Day message. The example below reveals text one character at a time and includes controls that remain usable without a mouse.

    const output = document.querySelector("#message");
    const button = document.querySelector("#start");

    button.addEventListener("click", () => {
      button.disabled = true;
      let index = 0;
      const typing = setInterval(() => {
        output.textContent += text[index++];
        if (index === text.length) clearInterval(typing);
      }, 55);
    }, { once: true });
  </script>

Customize the message, colors, and heading, then save the file as index.html. Use textContent rather than injecting untrusted HTML, and ask permission before publishing somebody’s name, photo, or private story.
