titles on character sheet tabs are not visible

I have this html code and the fields for the tabs don't show the names. They are just blank. Maybe someone knows what is wrong? <div class="sheet-all">     <input type="radio" name="attr_tab" class="sheet-tab sheet-tab1" value="1" title="Character" checked="checked" /><span></span>     <input type="radio" name="attr_tab" class="sheet-tab sheet-tab2" value="2" title="Skills & Spells" /><span></span>     <input type="radio" name="attr_tab" class="sheet-tab sheet-tab3" value="3" title="Combat" /><span></span>     <input type="radio" name="attr_tab" class="sheet-tab sheet-tab4" value="4" title="Gear & Notes" /><span></span>     <input type="radio" name="attr_tab" class="sheet-tab sheet-tab5" value="5" title="NPC Sheet" /><span></span>     <!--TAB 1 -->     <!-- Attributes -->

Title only shows when you mouse over something. You can use it to give special information you don't want visible all the time. You can show the names inside your spans: <input type="radio" name="attr_tab" class="sheet-tab sheet-tab1" value="1" title="Character" checked="checked" /><span>Character</span>

Thank you
