Kotak Penelusuran dalam Simbol

Menciptakan elemen kotak penelusuran tersembunyi dengan jQuery. Saat keadaan normal, kotak penelusuran akan tampak sebagai ikon kaca pembesar, dan saat ikon tersebut diklik, itu akan memicu kotak penelusuran di dalamnya untuk tampil:

HTML

<form class="search-form" action="/search" method="get">
    <div class="input-wrapper">
        <input type="text" name="q" placeholder="Search...">
        <a title="Search" class="sc" href="/"></a>
    </div>
</form>

  -webkit-border-radius:30px;
  -moz-border-radius:30px;
  border-radius:30px;
  overflow:hidden;
