title: My own 'jQuery'
body: <p>Why this[0][0].style.width = "" ? And my framework can't change value. How to make the function SetWidth work? The function SetWidth should change the value of CSS properties in class. </p>
  
  <pre><code>var Framework = function( nameOfClass ) {
      return new Framework.foo.init( nameOfClass );
  }
  
  Framework.foo = {
      init: function( nameOfClass ) {
          if (typeof nameOfClass === 'string') {
              nameOfClass = Sizzle(nameOfClass, document);
              this[0] = nameOfClass;
              return this;
          } else {
              return null;
          }
      },
  
      GetWidth: function() {
          return this[0][0].style.width;
      },
  
      SetWidth: function( nameOfClass, value ) {
          // ???
      }
  }
  
  Framework.foo.init.prototype = Framework.foo;
  
  window.Framework = window.$$ = Framework;
  
  //console.log(Framework('.mainBlock-fixsize'));
  </code></pre>
