    <p>I had a requirement to put 2 image within a band on a page and then make it responsive to various screen sizes. So below a and b would represent these images and the band in red. The gap between a and b needed to remain proportional tho a and b were of slightly different width as A was a circular logo and b was a rectangular logo.</p> <p><img src="https://i.stack.imgur.com/Gu7yJ.png" alt="enter image description here"></p> <p>So I got it to work by moving through various screen size and manually adjusted the css according to what I saw using media queries as below:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Welcome&lt;/title&gt; &lt;meta name="description" content="T"&gt; &lt;meta name="keywords" content=""&gt; &lt;meta name="author" content=""&gt; &lt;meta http-equiv="cleartype" content="on"&gt;

It was a lot of guessing and entering % values / saving the file / reloading the browser to see how it looked / adjusting again and so on. Gah! </p> <p>So I'm looking for a way to use math or a framework or some workflow algorithm to speed this up and take all the guess work out of it. My method was purely amateur hour but so far I cant find a better way to go at it when using percentages and media queries. This took me far too long.</p>

    2. COIm using dreamweaver on one screen and the browser on the other so i can edit-save-reload fairly quickly. Would firebug be an improvement on that? I'd still be guessing at the values wouldn't I? I'd like to find a way of calculating the values for such a "simple" layout without needing to resort to edit-save-reload. There must be some kind of math or design guidelines that allow computation of the various values upfront instead i stepped thru each of the screens and adjusted the media query values by sight. This would become exponentially more time consuming with just a couple more elements.

    3. COSorry I thought the 'Gah!' was specifically about saving / reloading the browser. Firebug can allow you to make incremental changes and see the result real time - so useful for me. If you have a lot of changes to make or do not know where to start, maybe there could be better.

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.
