I've figured this out. Finally! There's a simple way to do this. Like so:
<svg id="xbox" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 60.7"><title>xbox</title><rect width="200" height="60.68" style="fill:none"/><path d="M195.2,49.2l-11.8-16-11.5,16h-4.8L181.2,30,168.4,12.8h4.8l10.2,14,10.5-14h4.8L185.9,30,200,49.2Zm-90.7,0L90.4,30l12.8-17.2H98.4l-10.5,14-10.3-14H72.8L85.6,30l-14,19.2h4.8l11.5-16,11.8,16Z" style="fill:#0f7c10"/><path d="M131,31.3l-2.2-1.6a8.2,8.2,0,0,0,4.4-7c0-2.6-.9-9.9-12.1-9.9H106.4V28.4h-4.8l-2.9,3.5h7.7V49.2h14.7c8.3,0,13.1-4.2,13.1-10.9a8.6,8.6,0,0,0-3.2-7m-20.5-15h10.6c3.2,0,8,1,8,6.1s-2.9,6-8,6H110.5Zm10.6,29.1H110.5V31.9h10.6c4.1,0,8.9,1.3,8.9,6.4s-5.4,7.1-8.9,7.1m32.3-33.6c-10.3,0-17.3,7.7-17.3,19.2s7,18.8,17.3,18.8,17.5-7.6,17.5-18.8-7.3-19.2-17.5-19.2m0,34.2c-7.7,0-13.1-6.1-13.1-15s5.4-15.3,13.1-15.3S166.8,22,166.8,31s-5.5,15-13.4,15M8.9,8.6h0A31,31,0,0,0,0,30.4,32.5,32.5,0,0,0,6.1,48.9h.3C4.2,41.5,16,24.3,22,16.9h0C11.8,6.4,8.9,8.9,8.9,8.6m42.9,0h0a31,31,0,0,1,8.9,21.8,32.5,32.5,0,0,1-6.1,18.5h-.3c2.2-7-9.6-24.3-15.6-31.6h0C48.9,7,51.8,9.6,51.8,9.3M30.4,0A29.9,29.9,0,0,1,46.3,4.5h0c0,.3,0,.3-.3.3C40.3,3.5,31.3,8.3,30.4,8.9h0C28.1,7.7,19.8,3.2,14.7,4.8a.3.3,0,0,1-.3-.3h0A30,30,0,0,1,30.4,0m0,24.3h0c9.2,7,24.9,24.3,20.1,29.1h0a31.5,31.5,0,0,1-40.3,0h0C5.8,48.6,21.1,31.3,30.4,24.3h0" style="fill:#0f7c10"/></svg>
The problem was when you export an image from Illustrator (as many do) the artboard is not included in the exported SVG. The paths have nothing to base their calculations on.
In my case the max height for my images was
100px and I needed to base the CSS styles for these images based on their width and height. In CSS I use
vw units, or just plain old
100% if the SVG is to fill block space. This scales nicely. That way you haven't go to mess about setting the width and height in CSS to ensure it displays correctly.
I went through each logo and set the height to
100px and let the width auto calculate based on the aspect ratio. I then fit the artboard to the logo to remove any unused space.
I selected a rectangle and turned fill and stroke off and I ensured it was the exact same size as the artboard. Place this blank object at the back. Now when you export the path will have a base to work the calculations on.
To do this in code it appears you can wrap the paths in a
rect and set it's width and height, and then you can set the
viewBox to the same (keep aspect ratios the same). As shown in the example above. I haven't actually tested this but I will test and update.
