The challenge: Unfortunately there are still people using an older version than Internet Explorer 9. That causes a problem with the display of CSS3-generated RGBA colors. So far it has been necessary, to create a PNG, which means less efficiency in the developement of a website.
Our solution: On this page you can handle exactly this problem with a few clicks. Choose the color you want and adjust the level of transparency. You will find a link on the bottom of this page. Just copy and paste it into the code of your website – just like a regular RGBA.
