Hiding an element can be done by setting the display property to “none” or the visibility property to “hidden”. (http://www.w3schools.com/css/css_display_visibility.asp)
Try it without the display none:
element.style {
border: 1px solid rgb(0, 0, 0);
padding: 0px;
width: 800px;
height: 480px;
}
solved How can I find which file or code affected to my code in html, css
