![]() Use higher viewport values on headings, and watch them grow more quickly than the surrounding text. We can combine a base size in more steady units (say 16px) with a smaller viewport-relative adjustment ( 0.5vw), and let the browser do the math: calc(16px + 0.5vw)īy changing the relationship between your base-size and viewport-relative adjustment, you can change how dramatic the growth-rate is. We need something more subtle, with minimums and maximums, and more control of the growth rate. This direct scaling is clearly too dramatic for daily use. As you can see, fonts scale very quickly – adjusting from unreadably small to extra large in a very small range. Using simple viewport units for font-size has an interesting (dangerous) effect. It’s become very popular to use viewport units for responsive typography – establishing font-sizes that grow and shrink depending on the current viewport size. Let’s see what we can do! Responsive Typography While these units are derived from viewport height or width, they can all be used everywhere lengths are accepted – from font-size to positioning, margins, padding, shadows, borders, and so on. Sadly, and strangely, vmax units are not yet available on Internet Explorer or Edge. 10vmax will resolve to 10% of the current viewport height in portrait orientations, and 10% of the viewport width on landscape orientations. Viewport Maximum ( vmax) – A percentage of the viewport width or height, whichever is larger.10vmin will resolve to 10% of the current viewport width in portrait orientations, and 10% of the viewport height on landscape orientations. Viewport Minimum ( vmin) – A percentage of the viewport width or height, whichever is smaller.10vh will resolve to 10% of the current viewport height. Viewport Height ( vh) – A percentage of the full viewport height.A % length is relative to local context (containing element) width, while a vw length is relative to the full width of the browser window. The difference between % and vw is most similar to the difference between em and rem. 10vw will resolve to 10% of the current viewport width, or 48px on a phone that is 480px wide. Viewport Width ( vw) – A percentage of the full viewport width.The new units – vw, vh, vmin, and vmax – work similarly to existing length units like px or em, but represent a percentage of the current browser viewport. I thought it would be fun to review the basics, and then round-up some of my favorite use-cases.įour new “viewport-relative” units appeared in the CSS specifications between 20, as part of the W3C’s CSS Values and Units Module Level 3. tiff format now behaves perfectly in a rotated viewport.Viewport units have been around for several years now, with near-perfect support in the major browsers, but I keep finding new and exciting ways to use them. ![]() ![]() In the original reported issue, that imagery behaving badly is geotiff (didn't get the exact file extension format). Also, non-geolocated imagery behaves, in. ![]() I have done design on a long linear commuter rail project here in Northern California, and we have many UCS rotated viewports with geolocated imagery in the viewports, behaving perfectly. So, I now think we can narrow this down to image type in a rotated viewport. I know this because UCS rotate is a regularly used workflow for me, with images. I replied above and clarified that UCS rotate in viewport does not cause this original reported issue. When viewport is not rotated, the image behaves with zero shift. When the viewport is rotated, the image shifts. I have a teammate experiencing this original reported issue, inside Civil 3D 2018.
