Pure CSS3 Glossy Social Media Drop Down Menu

Pure CSS3 Glossy Social Media Drop Down Menu - Sebuah menu media sosial yang terbuat dari (hampir) murni CSS3. Di sini Saya menggunakan kombinasi CSS3 Gradien dan Box Shadow untuk menciptakan efek realistis. Pada dasarnya, tombol panah di sisi kanan adalah pseudo elemen dari elemen <label> yang kemudian Saya tutupi dengan elemen checkbox.

Pure CSS3 Glossy Social Media Drop Down Menu

Jadi, ketika Anda mengeklik tombol drop down di bagian kanan, maka yang terjadi sebenarnya adalah Anda sedang mengeklik elemen checkbox transparan yang berada di atas elemen palsu (pseudo elemen) dari <label> :

HTML

<div class="glossy-selectbox">
    <input type="checkbox">
    <label data-default="Share This Post!" data-focus="Select one of the social media service..."></label>
    <ul>
        <li><a class="social-rss" href="#" target="_blank">RSS Feed</a></li>
        <li><a class="social-facebook" href="#" target="_blank">Facebook</a></li>
        <li><a class="social-twitter" href="#" target="_blank">Twitter</a></li>
        <li><a class="social-google" href="#" target="_blank">Google+</a></li>
    </ul>
</div>
