The capture attribute specifies that, optionally, a new file should be captured, and which device should be used to capture that new media of a type defined by the accept attribute.

Values include user and environment. The capture attribute is supported on the file input type.

The capture attribute takes as its value a string that specifies which camera to use for capture of image or video data, if the accept attribute indicates that the input should be of one of those types.

When set on a file input type, operating systems with microphones and cameras will display a user interface allowing the selection from an existing file or the creating of a new one.

  <label for="soundFile">What does your voice sound like?:</label>
  <input type="file" id="soundFile" capture="user" accept="audio/*" />
</p>
<p>
  <label for="videoFile">Upload a video:</label>
  <input type="file" id="videoFile" capture="environment" accept="video/*" />
</p>
<p>
  <label for="imageFile">Upload a photo of yourself:</label>
  <input type="file" id="imageFile" capture="user" accept="image/*" />
</p>

Note these work better on mobile devices; if your device is a desktop computer, you'll likely get a typical file picker.
