    <p>I want to use a Compass generated icon-sprite for two different scenarios.</p> <ol> <li>Use the icon(s) in original size.</li> <li>Use it the same icon(s) as a smaller version using CSS3 property <code>background-size</code>.</li> </ol> <p>I first do this:</p> <pre><code>$logo-spacing: 20px; @import "logo/*.png"; @include all-logo-sprites; </code></pre> <p>Now I can use the general created CSS-classes like <code>.logo-twitter</code> etc.</p> <p>Two achieve the second result I could use this (<a href="https://gist.github.com/3410875">darren131 / gist:3410875 - resize sprites in Compass</a>):</p> <pre><code>@mixin resize-sprite($map, $sprite, $percent) { $spritePath: sprite-path($map); $spriteWidth: image-width($spritePath); $spriteHeight: image-height($spritePath); $width: image-width(sprite-file($map, $sprite)); $height: image-height(sprite-file($map, $sprite)); @include background-size(ceil($spriteWidth * ($percent/100)) ceil($spriteHeight * ($percent/100))); width: ceil($width*($percent/100)); height: ceil($height*($percent/100)); background-position: 0 floor(nth(sprite-position($map, $sprite), 2) * ($percent/100) ); } .my-other-div-with-small-logos { .logo-twitter { $spriteName: twitter; $percentage: 40; @include resize-sprite($logo-sprites, $spriteName, $percentage); } } </code></pre> <p>But if I have around 30 logos I would need to repeat this manually for each sprite-class.</p> <p>Is it possible to import the folder twice, once for the original size and a second time with the <code>backround-size</code> property? Or modify the mentioned method to create all classes automatically within another <code>&lt;div class="my-other-div-with-small-logos"&gt;</code> where the icons should appear smaller?</p> <p>Or am I thinking in the wrong direction here?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
