I want to Capitalize first letter only and other should be small using CSS

String is: 

SOMETHING BETTER 
sOMETHING bETTER
Something better

but the result should be

Something Better

Is this possible using CSS? To Capitalize first letter I am using 

text-transform: capitalize;

But not able to capitalize in each case. "I want to use CSS because in my application it has written every where hard coded but a class has been called everywhere."

css cpu-word capitalization
