I am using Visual Studio to build an application using
ASP.NET and VB.
Suddenly, it is displaying loads of errors on the CSS page.
Everything it is flagging is actually valid. I have checked:
'background-clip' is not a known CSS property name.
'background-origin' is not a known CSS property name.
'background-size' is not a known CSS property name.
'border-bottom-left-radius' is not a known CSS property name.
'border-top-left-radius' is not a known CSS property name.
'border-top-right-radius' is not a known CSS property name.
'box-shadow' is not a known CSS property name.
'overflow-x' is not a known CSS property name.
'overflow-y' is not a known CSS property name.
'text-shadow' is not a known CSS property name.
'url( ' is not a valid value for the 'background-image' property.
Why am I getting all these error messages?
