Cara Menggunakan Source Code
CSS tempat nya di dalam tag <style> atau <b:skin>. Contoh:
<style>
/* CSS tempel di sini */
</style>
Javascript biasa nya di letakkan di atas tag </body> Contoh:
<script type='text/javascript'>/*<![CDATA[*/
//Tempel Disini Script nya.
/*]]>*/</script>
</body>
HTML terserah mau pasang di mana. mau di template atau postingan terserah.
