GWT: Returning multiple styles for the same CSS field -

In a CssResource, can I return many style class names with the same method?

[Please make a mistake in the code - I am trying to relax from home, from memory) I have the following library code (which I can not change):

 < Code> Zero Render (ClientBundle 1 Bundle) {setInnerHtml ("& lt; div class = \" + bundle.css (). Style () + \ "/ & Gt;"); }   
 The bundle is straight forward:  
  Interface ClientBandle1 extension of the clientbundle {@ source ("css1.css") CSSRsource 1 css; }   
 and CSS processing:  
  interface CSSRSource 1 CSSRars {style1 (); }   
 and css1.css:  
  .style1 {width = 10; Height = 20}   
 Now - I would like _  partially  _ override "style 1" with other style (override height only, not width) From my own CSS (css2.css) However, my css2.css has been declared as such:  
  .style2 {height = 30}   
 So I partially override CSS 1 Want to Style1 CSS 2. With Style 2 (different category names).  
 If this vanilla is HTML, then I would have just written it:  
 ... import css1 again css2 ...  
     
 However, because it is GWT, I'll need something like this:  
  Interface ClientBundle 2 ClientBundle 1 {@Source ("css1.css "," Css2.css ") CSSRsource 2 css (); }   
 and CSS processing:  
  interface increases CSSRSSSource2 CSSResource1 {@CLASSAM ("Style1", "Style2") style ( ); }   
 But of course, the above is not possible in GWT above.  
 Is there a way to specify two style class names according to a style method?   
 
 
 Many options, none of which are exactly what you are asking for:  
 Add more from a class:  
 Any time you are applying the style, as you  & lt; Div class = "style1 style2" /> , add both styles if in UiBinder,  & lt; Do something like g: widget addStyleNames = "{css.style1} {css.style2}" /> , and if in Java, just add both sections:  
  widget. AddStyleNames (css.style1 () + "" + css.style2 ());   
 or  
  widget. AddStyleNames (css.style1 ()); Widget.addStyleNames (css.style2 ());   
 Override that style:  
 Why not more than one style rule for  style1  or  style2  Are you Many ways depending on what you have done:  
 css1.css:  
  .style1 {width: 10px; Height: 20px}   
 and css2.css:  
  .style1 {height: 30px}   
 The CssResource / ClientBundle:  
  Interface CssResource2 Extended CssResource1 {String (style); } Interface MyClientBundle {@ source ({"css1.css", "css2.css}) CSS Rarsource 2 CSS ();}   
 is expanding (more or less) Style:  
  .style1 {width: 10px; height: 30px}   
 Since the subsequent CSS rules override with the same weight already.  
 Alternatively, something like:  
 css1.css:  
  .style1, .style2 {width: 10px; height: 20px}   
 css2.css:  
  .style2 {height: 30px}   
  style1  with something Also the result will be 10x20 whereas with  style2  anything will be 10x30. < Code> @ClassName  annotations can be used to ignore pre-defined style for more or less using  CssResource2 .
