This site shows how I used CSS to create "pseudomodal" buttons. I defined the buttons to link to local HTML files. For drama I added animated horse .gif images. These green bordered buttons work very smoothly.
         This site seems to work correctly on many browsers including: Chrome, Opera, Internet Explorer, and Microsoft Edge. Initially it also works on FireFox but after a minute or so causes it to crash. It does not work on Safari and causes it to lock up. To try the demo click on the Start Demo button. If you need the HTML/CSS code click the About Code button.
