While utilizing HTML5 client-side validation in my web form, I've encountered an issue with the file field. It seems that the required error is not displaying as expected because the input type file is being hidden by CSS.
This is a snippet of my code:
<input id="imageUpload" class="form-control" type="file" name="image" placeholder="Photo" capture required>
The issue lies in the fact that browsers are unable to focus on hidden elements. One simple solution is to utilize opacity: 0 or visibility: hidden instead of using display: none.
#imageUpload {
opacity: 0;
}<form>
<input id="imageUpload" class="form-control" type="file" name="image" placeholder="Photo" capture required>
<input type="submit">
