Anchoring CSS Repeating Background Image

阅读更多关于 Anchoring CSS Repeating Background Image

I have a webpage with a header banner in the following configuration: <---Repeating Image Left--><---Banner Image---><---Repeating Image Right---> The page is designed with fixed width content, but the banner spans the entire width of the browser window (thus the reason for including repeating images on the left and right). The two repeating images are different and they are also not standard background images which can be positioned where-ever. Instead, the left image needs to be anchored/stuck to the left-hand side of the banner image and then repeat itself leftwards, from that point, as the

How do I convert a CSS background-position property from percentages into pixels?

阅读更多关于 How do I convert a CSS background-position property from percentages into pixels?

I'm centering a background right now (using background-position: 50% 50%; ), that I'd like to animate using Javascript. But, I want to be able to animate this using pixel measurements. Effectively I want to set the background-position to something like "50% + 10px". Is this possible using Javascript? I can possibly do it by finding the height of the background image and the height of the browser screen and do some arithmetic, but this seems like a convoluted solution. In the future this will be possible using CSS3's calc function. But since that's not widely supported right now, below is a

Different CSS background-image depending on month and year

阅读更多关于 Different CSS background-image depending on month and year

Basically, I have a div with text in it, and I want the background to display a different image depending on what month and year it is. How can I achieve this? Any help would be greatly appriciated! *I've prepared 4 years worth of monthly images labelled "month0_2011.png" to "month11_2014.png" already if that helps?* Add a .php extension to the CSS and use PHP code to determine that. Just use standard PHP tags. For example: body { background-image:url('<?php echo $currentImagePath ?>'); } Where $currentImagePath is the path to your image, determined beforehand (i.e. top of page) using PHP.

How to Inherit grandparent CSS not parent?

阅读更多关于 How to Inherit grandparent CSS not parent?

I have a feeling this won't be possible, but thought I'd ask anyway. <body> //body uses 'back' background <div id="div1"> //div1 uses 'front' background <div id="child1"> //child1: no backgrounds, so shows 'front' background </div> </div> </body> My body element uses a background image. (I'll call it the back background image) div1 uses a different background image (I'll call it the front background image), so the front background image covers over the main background image. div1 contains a child div child1 that doesn't use any background images, so it just shows the background image of its

I want to create a navbar with images on each end to make it purty. So, I created the HTML and CSS below and it worked great. My menu items are in a ul/li list. When I style the list to put the items all on one line, the images on the ends disappear. What's up with that? How do I fix it? The culprit is float: left; below. --- test.html --- <html> <head> <link rel="stylesheet" href="test.css" type="text/css"> </head> <body> <div id="container"> <div id="header-usernav" class="span-6 last large"> <div id="header-usernav-leftside"><div id="header-usernav-rightside"> <ul> <li>Register</li> <li
