Eu tenho um problema com o iOS9 sobre o css do site. Regras CSS funciona bem no Android e iOS8. mas no iOS9, o site estragou tudo. essa é a diferença ios8 e ios9.

Qual é o possível problema e como posso corrigir isso? Obrigado pela ajuda.

css:

section.destinations {
    float: left;
    width: 82.5%;
    display: inline-block;
    position: relative;
    overflow: hidden;
    margin: 0 auto;
    font-weight: 300;
    font-size: 1.25em;
}
.content-wrap {
    position: relative;
    border-radius: 5px;
}
.content-wrap section {
    margin: 0 auto;
    max-width: 1200px;
    text-align: center;
    padding: 10px;
    border-radius: 5px;
    background-color: white;
    display: block;
}
.destinations .promo {
    position: relative;
    background: #fff;
    webkit-box-shadow: 0 0 2px rgba(0,0,0,1);
    -moz-box-shadow: 0 0 2px rgba(0,0,0,1);
    box-shadow: 0 0 2px rgba(0,0,0,1);
    float: left;
    width: 23%;
    margin: 0 2.6% 20px 0;
    font-size: 10px;
    text-align: left;
    display: block;
}
@media screen and (max-width: 600px){
    section.destinations {
        width: 100%;
    }
}
@media screen and (max-width: 410px){
    .full .one-fourth {
        width: 100%!important;
        margin: 0 auto 15px!important;
     }
}

HTML:

<section class="destinations clearfix full tabs tabs-style-tzoid">
    <div class="content-wrap">
        <section id="section-tzoid-1" class="content-current">
           <!--column-->
            <article class="one-fourth promo" style="">

            </article>
            <!--//column-->
           <!--column-->
            <article class="one-fourth promo" style="">

            </article>
            <!--//column-->
            <div class="clearfix"></div>
        </section>
    </div>
</section>
