When we apply these attributes to an element, such as an image (represented here by the example ), we are controlling the physical space that the element will occupy on the page.

This is crucial to ensure a consistent layout and prevent the browser from making adjustments during page loading.

The important tip here is always to specify the “height” and “width” values for images.

<form>
  <label for="fname">First name:</label>
  <input type="text" id="fname" name="fname"><br><br>
  <label for="lname">Last name:</label>
  <input type="text" id="lname" name="lname"><br><br>
  <input type="image" src="img_submit.gif" alt="Submit" width="48" height="48">
</form>

By doing this, we reserve in advance the necessary space for the image, thus preventing the page from undergoing unwanted visual changes during loading.

These attributes not only impact the page’s aesthetics but also contribute to a more stable and predictable user experience, enhancing the overall design quality.
