>Solution :

You have your primary box container set to position: absolute and several positioning attributes that are not present on the image which is probably why everything is shifting. I don’t know what else this form and image are going to be put into but they don’t seem necessary in your example so I’ve removed them and added a flexbox .flexContainer to wrap your content in and that helps keep your content aligned in a single row. You could take it a step further and add a @media query (https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries) to control how the image reacts on mobile (for example, change the flex-direction to column so the image appears below the contact box instead of stretching inward on smaller screens.

.flexContainer {
  display: flex;
  flex-direction: row;
  flex-wrap: nowrap;
}

img {
  width: 100%;
  height: auto;
  height: 475px;
  cursor: pointer;
}

span {
  content: "\27F6";
}

label {
  padding-left: 10px;
  font-size: 16px;
  padding-top: 10px;
}

.box {
  height: 475px;
  background: green;
  padding: 40px;
  box-sizing: border-box;
  margin-left: 1%;
  cursor: pointer;
}

.box p {
  font-family: 'jmsans', sans-serif;
  padding: 0;
  margin: 0 0 40px;
  color: white;
  font-size: 40px;
  width: 467px;
}

.box input {
  margin-bottom: 30px;
  width: 466px;
  box-sizing: border-box;
  box-shadow: none;
  border: none;
  border-bottom: 2px solid #999;
  outline: none;
  padding-left: 10px;
  font-weight: bold;
  height: 56px;
}

.box input[type="submit"] {
  border-bottom: none;
  cursor: pointer;
  color: #fff;
  margin-bottom: 0;
}

.box form div {
  position: relative;
}

.box form div label {
  position: absolute;
  top: 10px;
  left: 0;
  color: #999;
  transition: 0.5s;
  pointer-events: none;
}
