.w-overlay improvments

I think i can avoid use of additional div with .overlay class by use of pseudo elements, shure work with image, need to try with div and other's thing

.w-overlay {
   posiiton: relative;
   overlay: hidden;
    -webkit-transition: all 0.4s ease-in-out;
    -moz-transition: all 0.4s ease-in-out;
    -ms-transition: all 0.4s ease-in-out;
    -o-transition: all 0.4s ease-in-out;
    transition: all 0.4s ease-in-out;
}

.w-overlay:after {
    content: '';
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: #252525;
    opacity: 0;
}

.w-overlay:hover:after {
    opacity: 0.7;
}

For image is also nice to scale, maybe i can make a class a part

.blog:hover .blog-img img {
    -webkit-transform: scale(1.1);
    -moz-transform: scale(1.1);
    -ms-transform: scale(1.1);
    -o-transform: scale(1.1);
    transform: scale(1.1);
}
