Display issues on your base demo page

Some elements display on top of each other on my mac on Safari, Chrome and Firefox (everything at the latest version, system and browsers).. ad well as on my Chrome on Samsung Tablet.. am too lazy to prepare a pack of screenshots, I don’t even know how to upload a zip simply on here, and don’t want to spend tome on this, I just wrote you this to inform you.. maybe test it around various browsers.. I cannot believe all my browsers would mess up the same on the same page and that I be the only one.. After resizing the window a few times it sometimes gets displayed correctly.. try it on several configurations.. you might see what I mean. The other pages and homepage samples seem fine.
