::file-selector-button

The ::file-selector-button CSS pseudo-element represents the button of an <input> of  type="file".

Syntax

selector::file-selector-button

Examples

<form>
  <label for="fileUpload">Upload file</label>
  <input type="file" id="fileUpload">
</form>

form {
  display: flex;
  gap: 1em;
  align-items: center;
}

input[type=file]::file-selector-button {
  border: 2px solid #6c5ce7;
  padding: .2em .4em;
  border-radius: .2em;
  background-color: #a29bfe;
  transition: 1s;
}
 
input[type=file]::file-selector-button:hover {
  background-color: #81ecec;
  border: 2px solid #00cec9;
}

Example with fallback for browsers supporting the -webkit prefix. Note that as a selector you will need to write out the whole code block twice, as an unrecognized selector invalidates the whole list.

Note that ::file-selector-button is a whole element, and as such matches the rules from the UA stylesheet. In particular, fonts and colors won't necessarily inherit from the input element.

<form>
  <label for="fileUpload">Upload file</label>
  <input type="file" id="fileUpload">
</form>

form {
  display: flex;
  gap: 1em;
  align-items: center;
}

input[type=file]::-webkit-file-upload-button {
  border: 2px solid #6c5ce7;
  padding: .2em .4em;
  border-radius: .2em;
  background-color: #a29bfe;
  transition: 1s;
}

input[type=file]::file-selector-button {
  border: 2px solid #6c5ce7;
  padding: .2em .4em;
  border-radius: .2em;
  background-color: #a29bfe;
  transition: 1s;
}

input[type=file]::-webkit-file-upload-button:hover {
  background-color: #81ecec;
  border: 2px solid #00cec9;
}
 
input[type=file]::file-selector-button:hover {
  background-color: #81ecec;
  border: 2px solid #00cec9;
}
