Dispersion by ipsfocus
Dispersion features an animated gradient background image which is randomized on each page load and overlaid by an image of your choice. The gradient is both created and animated (in compatible browsers) using css and your visitors are given the option of using a greyscale background by clicking a simple toggle button. The header collapses on-scroll, and stays at the top of the screen for easy access.
Easily enable, disable or modify theme features such as background images, logos, social media links, guest messages and colors. This makes modifications and upgrades very simple since little code changes are required.
Sticky, shrinking header
The header shrinks in size and sticks to the top of the page for easy access to user controls and the board index.
Animated gradient background
An animated gradient scrolls horizontally beneath your background image (which is a simple black & white jpg image reduced in opacity).
Pause/play animated effect
Each member can choose to either play or pause the animated gradient effect. This is especially helpful for weaker computers which may struggle to efficiently animate the gradient. The decision is saved via cookies.
The position of the gradient background is randomized on each page load.
Members can choose to use a greyscale background instead of the rainbow effect by clicking a simple toggle button. Their choice is saved via cookies and remembered for their return visit.
If enabled, your members can choose their own background image from a predefined selection and their choice is saved via cookies.
Dismissible global message
Display a message across the top of your site with important announcements. Once your members have seen the message, they can press the Dismiss button to remove it (until you configure a new one).
A customizable message can be shown to guests, prompting them to either register or login to your forum. Two designs, "billboard" and "alert" (shown) are available.
Social links can be enabled/disabled and customized to your own URL, allowing you to easily link to your social network pages (facebook, twitter, etc)
HTML logo with slogan
Easily add/edit your text logo and slogan from within the theme settings. If required, the text can be replaced by an image instead.
A mega footer with configurable column numbers and content can be enabled and customized all within the theme settings.
