    <p>Two images, one is 300x400 pixels (height x width), the other is 500x600. How can I make them appear side-by-side, scaled so they are the same height on screen, filling the whole width of the page (or container/div), without changing the aspect ratio of either image?</p> <p>I'd like an HTML/CSS way to do this -- something that works for more than 2 images as well if possible. Currently I manually calculate the width of each image (math below).</p> <p><strong>EDIT:</strong><br /> An example of what I'm trying to do:</p> <pre><code>&lt;img src="http://stackoverflow.com/content/img/so/logo.png" width="79%" style="float:left" border=1 /&gt; &lt;img src="http://stackoverflow.com/content/img/so/vote-favorite-off.png" width="20%" border=1 /&gt; </code></pre> <p></p> <p>Used formula below (or trial and error) to come up with 79/20 split. Note that 79 + 20 &lt; 100 -- if I set it to 80/20 then the images wrap due to the border. How can I do this without having to do any computation? The browser should be able to do it for me.</p> <pre><code>ah1 = 300 // actual height of image 1 aw1 = 400 // actual width of image 1 ah2 = 500 // actual height of image 2 aw2 = 600 // actual width of image 2 // need to calculate these: dw1 // display width of image 1, expressed as percent dw2 // display width of image 2, expressed as percent dw1 + dw2 == 100% s1 = dw1 / aw1 // scale of image 1 (how much it has been shrunk) s2 = dw2 / aw2 dh1 = ah1 * s1 // display height of image 1 = its actual height * its scale factor dh2 = ah2 * s2 // need to solve this equality to get equal display heights: dh1 == dh2 s1 * ah1 == s2 * ah2 dw1 / aw1 * ah1 == dw2 / aw2 * ah2 dw1 / aw1 * ah1 == (1 - dw1) / aw2 * ah2 dw1 * aw2 * ah1 == (1 - dw1) * aw1 * ah2 dw1 * aw2 * ah1 == aw1 * ah2 - aw1 * ah2 * dw1 dw1 * aw2 * ah1 + aw1 * ah2 * dw1 == aw1 * ah2 dw1 * (aw2 * ah1 + aw1 * ah2) == aw1 * ah2 dw1 == aw1 * ah2 / (aw2 * ah1 + aw1 * ah2) == 400 * 500 / (600 * 300 + 400 * 500) == 20 / (18 + 20) == 20 / 38 == 52.63% // which ends up as style="width:53%" which isn't quite right... </code></pre>

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.
