I have tried below code in my dev org and it is working fine. You can use it as it is:
  
<apex:page showHeader="false" controller="months">
<apex:form >
      <apex:outputPanel id="mn">  
      <apex:repeat value="{!items}" var="item">
        <apex:outputText value="{!item}"/> 
        <span style="{!IF(item!='December','','display:none;')}">&gt;</span>
     </apex:repeat>
     </apex:outputPanel>
        <apex:commandButton value="Click" action="{!myArrayItems}" rerender="mn"/>

</apex:form>
</apex:page>

Hi,

Do following changes in your vf page:
  
<apex:page showHeader="false" controller="months">
<apex:form >
        
      <apex:repeat value="{!items}" var="item">
        <apex:outputText value="{!item}"/> 
        <apex:outputText value=">" rendered="item!='December'"/>
     </apex:repeat>
        <apex:commandButton value="Click" action="{!myArrayItems}" rerender="mn"/>

</apex:form>
</apex:page>
