What is the best way to place text beneath an input field?

Although it may seem simple, I am new to this and could use some help. I have an input box:

<input type="text" name="username" id="username" class="form-control" value="{{username}}">
<div class="error" id="nameErr"></div>

I have a function that displays the message "username cannot be blank" in the error div if the input box for username is empty. It is currently working, but the message appears to the right of the input box when it should be below. Can someone help me fix this issue? Thank you!

Answer №1

To easily stack elements, simply set the display css property of the input to block

input { display: block; }

Choose the CSS selector that fits your application best. In this example, we used input for demonstration purposes.

By default, input elements are inline-block and will align side by side. Changing the display property to block will stack the input and div elements.

Answer №2

To position your error message next to the input field, simply set its display property to inline-block.

#nameErr {
  display: inline-block;
}

For a live example, check out this Codepen demo.

Answer №3

To quickly resolve this issue, try adding display: inline-block to the input tag. I recommend examining your page and experimenting with the html before transferring the changes to your css file once you are content with the results.

Answer №4

To ensure the error message appears below the input box, simply add display: block to the error class. By default, the class is set to "inline-block" so you will need to inspect and locate the class in order to make the adjustment.

Answer №5

Identifying the issues in your code can be challenging without a customized CSS style to guide you. To help you understand and potentially resolve the bugs, I've put together a simple example below. Try entering a character in the text field and then clearing it:

const input = document.querySelector('input')
const error = document.querySelector('.error')

input.addEventListener('keyup', e => {
  error.style.opacity = !input.value ? 1 : 0
})
* {
  font-family: sans-serif;
}

input {
  display: block;
  padding: 10px;
  width: 35vw;
  border-radius: 5px;
  border: 1px solid #00000022;
}

input:focus {
  border: 1px solid #1aa3e8DD;
}

input::placeholder {
  color: #000000AA;
}

.error {
  padding: 10px;
  padding-top: 5px;
  font-size: .75rem;
  color: #FF0000BB;
  opacity: 0;
}
<input type="text" name="username" id="username" class="form-control" placeholder="Your username">
<div class="error" id="nameErr">Username cannot be empty</div>
