body: <p>I have an ExtJs label in a field set and I am using ExtJs 3.4.</p>
  
  <pre><code>{

                  layout : 'hbox',
                  border : false,
                  defaults : {
                      //layout : 'hbox',
                      labelAlign : 'center'
                  },
                  items : [ {
                      xtype : 'label',
                      id : 'idOpen',
                      text : '',
                      width : 52.5,
                      height : 25,
                      labelStyle : 'font-weight:bold;',
                      border : true,
                      style : {
                          //background : '#6699FF',
                          color : 'black',
                          textAlign: 'center'
                      }
                  }.......
  </code></pre>
  
  <p>I need to add border to that label and bold label text. I've tried <strong>border : true</strong> but it's nor working.</p>
  
  <p><strong>labelStyle : 'font-weight:bold;'</strong> is also not working.</p>
  
  <p>And also I need to center label text within the label box. I've tried </p>
  
  <pre><code>style : {
  
                          textAlign: 'center'
                      }
  </code></pre>
  
  <p>It center t5he text horizontally but not vertically.</p>
  
  <p>How can I fix these issues ?</p>
