Hello Kevin Nguyen,
          Javascript can be used under script tag in visualforce page and html tags can directly be used as in html
following example shows how to do it. 
<apex:page >
    <apex:form >
    <!-- Javascript>
        <script>
            function check()
            {
                document.getElementById("datetime").innerHTML= Date();
                var image = document.getElementById('myImage');
                if (image.src.match("onbulb")) 
                {
                image.src = "offbulb.jpg";
                }
                else 
                {
                image.src = "onbulb.jpg";
                }   
            }
        </script>
        <apex:pageblock >    
                <apex:pageBlockButtons >
                    <apex:commandButton onclick="check()" value="click"/>
                </apex:pageBlockButtons>
                <!--<apex:variable value="offbulb.jpg" var="x"/>-->
                <apex:image onclick="check();" value="{!$Resource.bulb}" id="myImage" width="100" height="100"/>
        <!-- Html code -->
