jquery - Change Opacity of an Unclicked Element -

I have some elements on my webpage and I want to click on one of the elements when I click on it Is unchecked)

  
 & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "back" & gt; One class = "link" href = "# / portfolio / chicken.html" onclick = "gestionClic ('compteur11');" & Gt; & Lt; Div class = "element-image-back" & gt; & Lt; Div class = "element-image-back" & gt; & Lt; Img src = "./ Post thumbnail images / raspberrypyboard.jpg" /> gt; & Lt; / Div & gt; & Lt; / A & gt; & Lt; / Div> & Lt; / Div & gt;   
 When I click on an element, it is  class = "link"  which is clicked.  
 I tried to do this but it does not work:  
  $ ('.link'). Click (function () ($ ('. Element'). Sister () .animate ({session acety: 0.4}, 300); $ ('. Link') (function () {$ no ( 'Element'). Stop (). Animate ({obscurity: 1.0}, 300);});});    
 
 
  First:  Clear your HTML elements!  
  Second:  Work on my demo  
  $ ('. Element> img'). Click (function () {$ (this). ({Opacity: 0.4}) Brother Sister (). Chetan ({obscurity: 1});});   
 After clearing your HTML ...  
  & lt; Div class = "element" & gt; & Lt; Img src = "{SRC}" & gt; & Lt; Img src = "{SRC}" & gt; & Lt; / Div & gt;   
 Then you can use  
  demo:   
 
 if you're actually your impure If you want to use HTML, just do this ...  
  $ ('Element img'). Find (". Element"). Find ("img"). (This) .mate ({opacity: 1}); $ (this) .met ({obscurity: 0.4});} );  
  Demo:   
 
  Example in your case:   
 < Code> $ ('. Element & gt; .back & gt; .link'). Click (function () {$ (this). Value ({opacity: 1}); $ (this) .parents (". Element") .find ("front."; Element-image-front "). ({Opacity: 0.3});});   
  One more click:   
  $ ('. Element & Gt; Forte & gt; .element-image-front ') .click (function () {$ (this) .animate ({opacity: 1}); $ (this) .parents (". Element"). ( ". Back> .link"). Animate ({obscurity: 0.3});});   
 Should be done in a function, but your HTML is unclear. Code 2 Function for% Work and 100% Full Focus Elements
