سلام خدمت کابران عزیز وبسایت پرنیان طرح
در این مقاله برای شما یک پس زمینه بسیار حرفه ای و جذاب رو آماده کردم که با کلیک بر روی صفحه شیش ضلعی ها بصورت جذابی روشن و خاموش میشوند.
دمو نمایشی این پس زمینه حرفه ای :
پس زمینه فوق با سه زبان hml و js و css ساخته شده است که بصورت جداگانه در زیر هر سه کد را برای برنامه نویسان عزیز قرار میدهم :
بخش html کد ها :
[php]
<div id=”jsi-hex-container” class=”container”></div>
[/php]
بخش css کد ها :
[php]
html, body{
width: 100%;
height: 100%;
margin: 0;
padding: 0;
overflow: hidden;
}
.container{
width: 100%;
height: 100%;
margin: 0;
padding: 0;
background-color: #000000;
}
[/php]
بخش js کد ها :
