Unlike the Android App, the website doesn't show what legal representative 30.06, 30.07 or 51% signs looks like.
I would recommend adding an image of those three signs as is done on the app. In addition, the website should have the exact wording spelled out either by image, text, or via link to corresponding Texas Penal Code. This app does all three.
In addition, the website makes reference to "Gunbuster" signs or others that are not valid. Images of these examples would be of benefit too.
