  • Provide examples: Help users understand the expected format of input, such as "YYYY-MM-DD" for date input.
  • Improve form accessibility: Provide context for screen readers and assistive technologies so users understand the intended use of input fields.

Using the placeholder attribute

To use the placeholder attribute in Vue.js, please set the placeholder attribute in the input element, as follows Shown:

<code class="html"><input type="text" placeholder="Your name"></code>
Copy after login

<code class="css">input::-webkit-input-placeholder {
  color: #aaa;
  font-size: 12px;
}</code>

  • Keep it relevant to the input field: Placeholder text should correspond to what the user expects to input.
  • Short and clear: Placeholder text should be clear enough, but not lengthy or confusing.
