About what you buy
In the zip you downloaded there are PSD and PNG files. This is NOT working CSS/HTML pricing table. Here you get only the psd files you need to edit it and use where or how you want.
Two folders are here:
In PSD folder you can access to the files you bought and in PNG folder you can preview them (if you don’t) want to slow your computer opening in with photoshop.
In the preview are all the versions you get in the download file.
Each element is vector and you can edit the color by just double clicking on the elements. The design is friendly to older browsers (i say again, this is only PSD)
