I am currently working on a site. I want to create custom radio buttons. The background of the website is an image. So I want the radio button to seamlessly integrate with this background image. I have created the radio button and every time I crop it on paint.net, it comes out with a square black background. The image is saved as a GIF. How can I remove the black background?
Not sure what is your level of experience or which software is available at your disposal. But a fast answer would be to use a format hat supports transparency.
So you make sure the area around the circle is transparent then export your image as a PNG 24bit with transparency.
It could be done by Photoshop easily not sure how to do it with paint.net.
Let me know
