Question

Floating left 'li' not working in ipod, android devices. But it works perfect in all major broswers in laptop / destops. Code is here:

<ul class="clsvideos clearfix">
<li>
    <div class="home-thumb">
        <div class="home-play-container">
            <div class="play-button-hover">

.clsvideos li:first-child {
width: 140px;
float: left;
padding: 14px 10px 0 0;
display: block;
}
.clsvideos li {
height: 155px;
width: 140px;
padding: 14px 10px 0 9px;
border-right: 1px dotted #CFCFCF;
border-bottom: 1px dotted #CFCFCF;
float: left;
}

Awaiting for a solution at the earliest

Answer 1

Actually the problem was, the developer hadn't closed the last 'div' inside 'li' which led to this bug...

"So be careful with front-end code while writing core php". This is what the advise I have to my developer.
