Full page background images CSS

If you want to cover the background of your web page, I suggest you do 2 things:
Reduce the file size of the image using the technique shown at https://orbitingweb.com/blog/optimizing-jpeg-images/. You should make sure you are using the correct image format. Here is a guide https://www.diffen.com/difference/JPEG_vs_PNG.
Use the following CSS code in your stylesheet:
html {
background: url(img/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='img/bg.jpg', sizingMethod='scale')";
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='.img/bg.jpg', sizingMethod='scale');
}

PHP resize image before base64 encoding

It took me a while to work this out, but it was worth it. base64 encoding can be really useful in presenting and storing images on the web. However you don't want to add a 2000 pixel width base64 encoded image to your database. Here's how to resize the image before it goes in.

<?php
$file = 'mypic.jpg';
$image = imagecreatefromjpeg($file);
$image = imagescale($image , 100);
ob_start();
imagejpeg($image);
$contents = ob_get_contents();
ob_end_clean();
$dataUri = "data:image/jpeg;base64,".base64_encode($contents);
echo '<img src="'.$dataUri.'" />';
?>

Simple layout #9

This one is very similar to Simple layout #8 (hope it's not a trend), but for 2 major differences. I have included a background image and colour in the header. I have increased and broadened the font of the header. These 2 small differences are to fall in line with current website trends.

See demo.

Resize Background Image

I've often seen background images being resized on designer websites and wondered, how do they do that? Anyway, here's how.

See demo.

<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset="UTF-8">
<title>Resize Background Image</title>
<style type="text/css">
html, body
{
margin:0;
font-family:Sans-serif;
}
#background
{
position:absolute;
z-index:-1;
width:100%;
height:100%;
}
#mainContent
{
margin:0 auto;
width:800px;
padding:10px;
background:#FFFFFF;
color:#A3A3A3;
}
</style>
</head>
<body>
<img id="background" src="http://farm5.static.flickr.com/4140/4947943522_5ba46ef4df.jpg" alt="windFarm" />
<br /><br />
<div id="mainContent">
<h1>Hello World!</h1>
</div>
</body>
</html>

jQuery Image Overlay

I've been looking for a nice, simple image overlay. One which wouldn't make me create unnecessary code around my images. I found this one called jcaption. It's a very simple implementation, so I thought I'd share it with you.

See demo.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Image overlay</title>
<style type="text/css">
html
{
font-family:Sans-serif;
}
.caption
{
position: relative;
}
.caption p
{
position: absolute;
bottom:0;
left:0;
background:#A3A3A3;
color:#FFFFFF;
}
</style>
<script src="http://www.google.com/jsapi"></script>
<script>
google.load("jquery", "1");
google.load("jqueryui", "1");
</script>
<script src="scripts/jcaption.min.js"></script>
<script>
$(function()
{
$('img').jcaption({
animate: true, show: {height: "show"},hide: {height: "hide"}
});
});
</script>
</head>
<body>
<div class="caption">
<img src="http://farm5.static.flickr.com/4092/4954283598_7e64000a5c_m.jpg" alt="purpleRingSmall" />
</div>
</body>
