Hello,

That’s strange. Please add this css to fix it:

@media (max-width: 480px){
.blog-article.standard-style .content {
    width: 40% !important;
}
.post_style-modern .span12 > .blog-article > .media {
    margin-left: 0 !important;
    margin-right: 0 !important;
    max-width: 300px !important;
}}

Best regards!
