function togglegallery() {    var x = document.getelementbyid('image-gallery');    if (x.style.display === 'none') {      x.style.display = 'block';    } else {      x.style.display = 'none';    }  }
#image-gallery {    display: block;    width: 600px;    border: 1px solid black;  }    #image-gallery li {    width: 150px;    height: 150px;    color: white;    text-align: center;    margin: 10px;    background-color: gray;    display: inline-block;  }    button {    display: none;  }    @media (max-width: 600px) {    #image-gallery {      display: none;      width: 100%;    }    button {      display: block;    }  }
<div class="container">    <button onclick="togglegallery()">click view images</button>    <p>i want reveal content on mobile 1 button click. </p>    <div id="image-gallery">      <ul>        <li>image 1</li>        <li>image 2</li>        <li>image 3</li>      </ul>    </div>  </div>  <!--container-->

in togglegallery() function, replace condition x.style.display === 'none' x.style.display !== 'block'.

the display property not equal none meaning function set none in condition, meaning next time function , set block. rather checking display not equal block work first time.
