php - CSS - website overlay when page is loaded -
im setting website different navigation structure compared whats traditional, , want add overlay on top of site loaded when user enters site first time.
the overlay should fullscreen, black "opacity=50", , im going add simple text how use website. should go away when klicking
im web designer, , have limited knowledge in coding. (some css/html/php)
is there simple way add class this?
thanks feedback
simple enough html
<div id='overlay'> <div id='contents'>... </div>
the css:
#overlay { background-image : url('images/overlay.png'); width:100%; height:100%; position: fixed; top: 0; left: 0; } #contents { width: 300px; height: 300px; margin: auto; }
i use image overlay because opacity setting carried through contents area , no javascript required or ever needs used type of content.
