Educate the Azure portal developers in basic UX principles
I just went to try and create an Azure storage account and was confronted with the screen in the attached screenshot. Note the control in use for the fields "Deployment model", "Performance" and "Secure transfer required". Each of these fields requires the user to select one of two possible options. Standard web design provides two controls suitable for this purpose - the dropdown selection and the radio button. You have ignored these standard controls which have proven their utility over two and a half decades and instead created your own. And I can tell you immediately that yours sucks because it violates the first rule of UX design - it has to be intuitive. Your control gives two options and only distinguishes between them by background colour. Not only does that violate web accessibility guidelines, it is confusing even for people who don't have a disability. Am I supposed to conclude that a dark background or a light background indicates the selected option? The dark background stands out, so maybe that's it. Then again the dark background is not a million miles away from the good old "greyed out" colouring that has always indicated a disabled option, so maybe it's the light background that is active.
The only way I have of determining which is which is to start experimenting by clicking with my mouse. That's a very poor UX - the meaning of the control should be apparent without having to resort to playing with the UI. A good old selection or radio buttons would have been immediately obvious.
Send your web developers back to school because they appear to have missed day 1.
What if I couldn't use a mouse?
