Non riesco a far coesistere queste due codici
Sto cercando di far aprire una pagina cliccando su un pulsante con una animazione.

La pagina principale ha questa impostazione :
codice HTML:
codice HTML:
<!-- start servizi -->
<div id="servizi" class="text-center">
<div class="container">
<div class="row">
<div class="col-md-12 wow bounce">
<h2>Di cosa ci occupiamo</h2>
</div>
<div class="col-sm-6 col-md-3 wow fadeInLeft" data-wow-delay="0.6s">
<div class="plan plan_one">
<h4 class="plan_title">Prova</h4>
<ul>
<div align="left">pppppp ppppppppppp pp,....</div>
</ul>
<button class="btn btn-warning">Continua</button>
</div>
Questo è il file contenente "style"
