use one media-container class on all images and the video

this gets reused a fair amount can instead make one class

.media-container {
  overflow: hidden;
}

.media-container img,
.media-container video {
  display: block;
  width: 100%;
}

then add width and padding specifics to instances of that class

.content-image-box .media-container {
  width: 35%;
}

@media only screen and (max-width: 895px) {

  .content-image-box .media-container {
    width: 100%;
  }
}
