What is the recommended approach for changing the appearance of form elements in PHP applications?

When changing the appearance of form elements in PHP applications, it is recommended to use CSS to style the elements. This allows for separation of concerns and easier maintenance of the code. By adding classes or IDs to form elements, you can target them specifically with CSS to achieve the desired visual changes. 

<form>
  <input type="text" name="username" class="input-field">
  <input type="password" name="password" class="input-field">
  <button type="submit" class="submit-button">Submit</button>
</form>
```

CSS:
```css
.input-field {
  padding: 5px;
  border: 1px solid #ccc;
  border-radius: 3px;
}

.submit-button {
  background-color: #007bff;
  color: white;
  padding: 5px 10px;
  border: none;
  border-radius: 3px;
  cursor: pointer;
}

.submit-button:hover {
  background-color: #0056b3;
}
