I want to show a preloader on my website before the content loads,However when i choose a animated preloader image with transparent background the edges look very jagged. How to I modify the image or is there a way to have a transparent background to animated gifs?
I am using the preloaders from preloader.net
The first and probably easiest option you have is to use spin.js. “It dynamically creates spinning activity indicators that can be used as resolution-independent replacement for AJAX loading GIFs.”
If a script is not an option or you want to have a different spinner you have to create a .gif with no anti-aliasing that is bigger than the spinner you want to use and scale it down with html.
Original spinner without edges (without anti-aliasing, therefore it has a pixelated edge):
But if this spinner gets scaled down, it looks nice:
Be sure to use
img {
-ms-interpolation-mode:bicubic;
}
to make it also look pretty in older IEs.
You can use a site that helps you generate your spinner. A great option is : loading.io
