为什么我的媒体查询对我的 CSS 没有影响？

Question

I'm making a counter that is contained within a box. I'm trying to make this counter responsive to different screen sizes, but the media query I'm trying to use will not work for some reason.

I have tried changing the the device width to below 768px but the query has no effect on the counter and I'm not sure why. I have included the HTML/PHP code for the counter as well as the CSS. Can anybody figure out why it's not working

I have made sure this tag is included in the head of the document.

HTML:

<div class="counter col_fourth counter-container" id="bottleCounter">
  <i class="fas fa-times counter-closer" onclick="closeCounter()"></i>
    <div class="counter-row">
        <!--NB 19.11.21 green bottle image next to counter-->
        <img class="bottle-icon rotate-bottle" 
        src="https://img.resultclothing.net/icons/Green_Bottle.png" alt="water bottle">
        <h2 class="count-title count-number">
        <?php 
            $bottleCount = str_split(intval($var)); 
        echo '
        <span class="timer counter-digit" data-to="'.$bottleCount[0].'" data-speed="5000"></span>
        <span class="timer counter-digit" data-to="'.$bottleCount[1].'" data-speed="5000"></span>
        <span class="timer counter-digit" data-to="'.$bottleCount[2].'" data-speed="5000"></span>

        <span class="timer counter-digit" data-to="'.$bottleCount[4].'" data-speed="5000"></span>
        <span class="timer counter-digit" data-to="'.$bottleCount[5].'" data-speed="5000"></span>
        <span class="timer counter-digit" data-to="'.$bottleCount[6].'" data-speed="5000"></span>';
        ?>
        </h2>      
    </div>
    <p class="count-text"><?php echo constant('LANG_FOOTER_BOTTLES_REC'); ?></p>

Answer 1

the missing closing bracket

Add the closing bracket to you keyframe

    @-webkit-keyframes shake {
        from{
            -webkit-transform: rotate(35deg);
        }
        to {
            -webkit-transform:rotate(15deg);
            -webkit-transform:rotate(25deg);   
      } 
    }
