I have installed the Java SE version of Eclipse Mars 2, then I have installed the WTP tools for Java EE for the web development (or I think that I have download all these stuff but I am not so sure).
The problem is that if I write code into an html page, I can see the code syntax coloured according to the tab but I have not the code hints for the inline CSS.
So for example if I try to put some inline CSS on a tag I have the autocomplete function for the style attribute (if I write something like st on an html tag, pressing CTRL + SPACE Eclipse automatically write style="" for me) but I have not the autocomplete function for the inner CSS.
So for example if I write style="margin-" and the click CTRL + SPACE I have not the relative hints for the possible CSS attributes.
The strange thing is that if I open a .css file here the autocomplete function works fine.
What am I missing? How can I solve this issue?
