Push Menu - How to push body

Question

I have a menu that opens to the right. My issue is that I want the body to resize after I have opened the menu. The menu is 300px wide and I want the body to resize to take up the remainder of the screen. I saw a few examples, but all they do is shift the body so part of it is not visible and off screen. You can see my example here

<nav class="side-nav hidden">

    <div>
        <div class="open-menu-side" id="side">
            <button class="hamburger hamburger--squeeze" type="button">
              <span class="hamburger-box">
                <span class="hamburger-inner"></span>
              </span>
            </button>
        </div>

        <ul class="side-nav-ul">
            <a href="#"><li class="block">Home</li></a>
            <a href="#"><li class="block">Profile</li></a>
            <a href="#"><li class="block">Blogs</li></a>
            <a href="#"><li class="block">Following</li></a>
            <a href="#"><li class="block">Settings</li></a>
            <a href="#"><li class="block">Logout</li></a>
        </ul>
    </div>
</nav>
<header id="pushed">
    <nav>
        <div class="open-menu" id="main">
            <button class="hamburger hamburger--squeeze" type="button">
              <span class="hamburger-box">
                <span class="hamburger-inner"></span>
              </span>
            </button>
        </div>
        <div class="brand">Login!</div>
    </nav>
</header>

As mentioned in the comment, this is what you could do. Add a class to your HTML body when the menu is opened and add a padding-right equals to the width of the menu.

$(".hamburger").on("click", function() {
  $(".hamburger").toggleClass("is-active");
  //add menu-active class to document body
  $('body').toggleClass('menu-active');
  $(".side-nav").toggleClass("hidden");
  if ($("#side").hasClass("is-active")) {
    $("#main").toggleClass("hidden");
  } else if (!$("#side").hasClass("is-active")) {
    $("#main").toggleClass("hidden");
  }
});

html,
body {
  padding: 0;
  margin: 0;
  height: 100%;
  background-color: black;
  box-sizing: border-box;
}

button:focus {
  outline: 0;

.side-nav {

  width: 300px;

.open-menu-side {
  position: relative;
  display: block;
  height: 80px;

  text-align: center;

}
