centrare iframe con div

[ans66]

Non riesco a centrare iframe dentro a div, in un sito responsive, sia @media min-width 0px che @media min-width 400px. Sembra funzionare unicamente a schermo inferiore di 400px. Ho utilizzato @media screen and (min-width: 0px o 400px) perchè sembra l'unico funzionante.

<div id="container">
<iframe id="slider"  width="100%" height="100" src="./slider/slider.php" scrolling="no" frameborder="0" onload="calcHeight(this);"> </iframe>
</div>

@media screen and (min-width: 0px) {

body

div#container  { 
                  position: absolute;
                  top: 50%;
                  left:10%; 
                  width: 80%
                  
               }

div#page-wrap  { position: absolute; top: 500px ; left:10%; width: 80%   }

                                        }
                                   
                                   
                                   }



@media screen and (min-width: 400px) {

div#container  { 
                  position: absolute;
                  top: 50%;
                  left: 40%;
                  -ms-transform: translate(-50%, -50%); /* IE 9 */
                 -webkit-transform: translate(-50%, -50%); /* Safari iOS */
                  transform: translate(-50%, -50%); /* Rest of browsers */
                  width: 400px; height: 218
        
                  }
div#page-wrap  { position: absolute; top: 500px ; left:40%; width: 60%   }

                                      }

div#slider  { width: 400px; height: 218 }

Grazie per l'aiuto

non sono riuscito a trovare una soluzione che funzioni. Penso che sia giusto postare i file php e css interamente:

@media screen and (min-width: 0px) {

div#container  { 
                  position: relative;
                  top: 50px;
                  left:10%; 
                  width: 80%
                  
               }

div#page-wrap  { position: relative; top: 50px ; left:0%; width: 100%   }

                
                                        }
                                   
                                   
                                   



@media screen and (min-width: 400px) {

div#container  { 
                  left: 10%;
                  position: relative;
                  top: 50px;
                  width: 80%;
               }

#slider  { width: 400px;  height: auto; margin: auto;   }
div#page-wrap  { position: relative; top: 50px ; left: 0%; width: 80%;  }

ho trovato una soluzione. Ho chiuso il DIV container prima del frame per poi riaprirlo successivamente. Ho creato un nuovo div "fram" attorno all'iframe slider.

Poi le seguenti istruzioni CSS hanno sortito l'effetto sperato:

#frm   {  position: relative; top: 0px; width: 400px; margin: auto;   }

visto che iframe slider non era più all'interno del DIV container
