Css display:grid column become hidden on smaller screen devices


I have the following html page :

.main {
  display: grid;
  grid-template-columns: 1fr 2fr;
  /*font-size: 55px;*/
}

.main>div {
  height: 200px;
}

.main>div:first-child {
  border: solid 3px red;
}

.main>div:last-child {
  border: solid 3px blue;
}
<div class="main">
  <div>
    contents 1
  </div>
  <div>
    contents 2
  </div>
</div>

Expected result on normal screens And the result is fine and as I am expecting(the blue div has as twice width as the red div). But when I change the screen size to less than 246px the blue div started to hide under the browser edge :

Some portion of the blue div is hidden on screens less than 246px

How can I keep the ratio of two div in smaller screen sizes ?

Update: font-size has been removed but the problem still exists.


Solution

  • You need to add viewport meta tag and also clean up initial margin and padding of html and body tags

    final codes should be as follow

    <!DOCTYPE html>
    <html>
    
    <head>
        <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
        <style>
            html,
            body {
                margin: 0px;
                padding: 0px;
            }
    
            .main {
                display: grid;
                grid-template-columns: 1fr 2fr;
            }
    
            .main>div {
                height: 200px;
            }
    
            .main>div:first-child {
                border: solid 3px red;
            }
    
            .main>div:last-child {
                border: solid 3px blue;
            }
        </style>
    </head>
    
    <body>
        <div class="main">
            <div>
                contents 1
            </div>
            <div>
                contents 2
            </div>
        </div>
    </body>
    
    </html>
