Hi all,

I'm developing a system at present, and one of the requirements is that the site can be resized using a selector.  I can see that there have been discussions about this in the past and that telerik recommend that 3 different custom skins be developed and have a switching mechanism to achieve this.  My graphic designer isn't very happy about having to make 3 skins, so I'm trying this approach with jquery:

<script type="text/javascript">
      $(document).ready(function () {
          $("#textZoom1").click(function () {
              $("body").css("zoom", "1");
              $.cookie("HRI-ZoomLevel", "1");
          });
 
          $("#textZoom2").click(function () {
              $("body").css("zoom", "1.1");
              $.cookie("HRI-ZoomLevel", "1.1");
          });
 
          $("#textZoom3").click(function () {
              $("body").css("zoom", "1.2");
              $.cookie("HRI-ZoomLevel", "1.2");
          });
 
          var zoomLevel = $.cookie("HRI-ZoomLevel");
          if (zoomLevel != null) {
              $("body").css("zoom", zoomLevel);
          }
      });
  </script>


When I do this, the buttons (and tabs) look slightly wrong as demonstrated in the attachments (using the demo site)

I can adjust the padding to the background position of the button and apply a different css class to the body for each zoom level, but this just seems messy.

Is there a fix for this issue, or would you recommend that I force my designer to make 3 skins?

Thanks for your time.

Hello,

As discussed earlier, when a sprite image is used it can not be zoomed - the result is the one showed in your attachments.

I would recommend not to force your designer to make more custom skins, but to use CSS3 and button type link button - this way you`ll skip the sprite images and will have more detailed control over all and the zoom will work fine:

<head runat="server">
    <title></title>
    <style type="text/css">
        a.rbLinkButton.RadButton {
            border-radius: 6px;
            color: #fff;
            /* IE9 SVG, needs conditional override of 'filter' to 'none' */
            background: -moz-linear-gradient(top, #c7c7c7 0%, #6f6f6f 100%); /* FF3.6+ */
            background: -webkit-linear-gradient(top, #c7c7c7 0%,#6f6f6f 100%); /* Chrome10+,Safari5.1+ */
            background: -o-linear-gradient(top, #c7c7c7 0%,#6f6f6f 100%); /* Opera 11.10+ */
            background: -ms-linear-gradient(top, #c7c7c7 0%,#6f6f6f 100%); /* IE10+ */
            background: linear-gradient(top, #c7c7c7 0%,#6f6f6f 100%); /* W3C */
            filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#c7c7c7', endColorstr='#6f6f6f',GradientType=0 ); /* IE6-8 */
        }
         
        a.rbLinkButton.RadButton:hover {
            color: #000;
            /* IE9 SVG, needs conditional override of 'filter' to 'none' */
            background: -moz-linear-gradient(top, #ffe68b 0%, #fff3c9 100%); /* FF3.6+ */
            background: -webkit-linear-gradient(top, #ffe68b 0%,#fff3c9 100%); /* Chrome10+,Safari5.1+ */
            background: -o-linear-gradient(top, #ffe68b 0%,#fff3c9 100%); /* Opera 11.10+ */
            background: -ms-linear-gradient(top, #ffe68b 0%,#fff3c9 100%); /* IE10+ */
            background: linear-gradient(top, #ffe68b 0%,#fff3c9 100%); /* W3C */
            filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffe68b', endColorstr='#fff3c9',GradientType=0 ); /* IE6-8 */
        }
         
        a.rbLinkButton.RadButton:active {
            color: #000;
            /* IE9 SVG, needs conditional override of 'filter' to 'none' */
            background: -moz-linear-gradient(top, #f8d04c 0%, #feed76 100%); /* FF3.6+ */
            background: -webkit-linear-gradient(top, #f8d04c 0%,#feed76 100%); /* Chrome10+,Safari5.1+ */
            background: -o-linear-gradient(top, #f8d04c 0%,#feed76 100%); /* Opera 11.10+ */
            background: -ms-linear-gradient(top, #f8d04c 0%,#feed76 100%); /* IE10+ */
            background: linear-gradient(top, #f8d04c 0%,#feed76 100%); /* W3C */
            filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#f8d04c', endColorstr='#feed76',GradientType=0 ); /* IE6-8 */
        }
    </style>
</head>
<body>

    <telerik:RadButton ID="rb1" runat="server" ButtonType="LinkButton" Text="Link Button" Height="35"
        Skin="Default">

    </form>
