This works, except the devicename has the SEPxxxxx in front of the mac address. Is there a way to do a right () command, or run a seperate query that will return just the MAC address, as well as the.For most devices, screen resolution will be the default viewport width. So my screen has 1280 logical pixels in width and 800 pixels in height i.e, 1280x800 is my screen resolution ( Note: 2560 is device/native resolution and 1280 is my screen resolution ). For instance, the MacBook Pro Retina, iPhone 4 and above report a device pixel.Yes, you can.
I never meant to be absolutely prescriptive about ems as units—use whatever feels natural and appropriate for your design strategy. Keep that in mind if you cite or otherwise put stock in this post. Nonetheless! You should note that the zooming behavior has long since been made consistent in browsers (i.e. And the zooming behavior cited here was always meant more as a sidelong example than a core argument. Ems) and layout definitions (e.g. I still like the notion of the metaphorical connection between content-based sizing units (e.g. ![]() This naturally seems like a pixel dimension. And yet the vast majority of us still write width-based media queries in pixels, e.g.: all and (min-width: 500px) screen and (max-width: 800px) It’s a natural thought process: for windows or screens of particular width ranges, we want to flow our content in a particular way. Font units aren’t pixels or points anymore, they’re percentages (typically for top-level baseline reset) or, more often, ems. Instead of using fixed-width layouts, we enlightened web devs and designers use percentages in our CSS. In an Ethernet local A core tenet of Responsive Web Design (RWD) is fluidity and proportion. For example, in IP Version 4, the most common level of IP in use today, an address is 32 bits long. I’m not that old but, man, it’s hard to see the contents of a Wikipedia article on a 23″ monitor from 10 feet away.As I zoom in, that is, make the text larger in my browser, I’m no longer at a 14pt/16px baseline. Low-sight users might do it, I know I do it when I’m surfing the web on my Mac Mini from the couch across the room. Baseline expectationsYou may have seen the rule of thumb (useful, admittedly!) that makes the following general equation in terms of baseline font sizes in CSS: 100% = 1 em ~= 16px ~= 14ptThis means that, at your baseline, that is, before you’ve adjust font sizes in any child elements, the default font size in the browser is usually approximately 16px and usually approximately 14pt but always 100% and 1em.If we start from a baseline of 16px, you may well wonder what the difference (beyond academic) is between a media query like: all and (min-width: 400px)And one like this, that uses ems multiplied against the 16px baseline approximation: all and (min-width: 25em)Here’s the 64-dollar question or whatever:What happens when the baseline is not 14pt/16px?On Ye Olde Desktop Web, this situation most often comes about (“most often” is unscientific here, but I’m willing to toss out the hypothesis, at least) from user-intiated zoom in browsers. There are some tried-and-true numbers one can shoot for that make for the “right” number of letters (and thus words) per line for comfortable human reading.Thus actual column width is a function of font size and ems-per-line. For various screen widths, our site’s nav has a few different behaviors.In pixels at normal zoom, the nav elements fit in a line roughly at a width of around 656px. Case study: Our navOur creative director and CSS wizard extraordinaire, Aileen, whipped us up a beaut of a responsive new site layout. Pixel-defined content holders that float might wrap awkwardly as the content in them swells. Pixel-defined content holders no longer have comfortable amounts of words per line. Media Query Devices Full Set OfI’m using the Chrome browser, and I’m viewing our site with a window about 670 pixels wide. But what happens if a user has his or her zoom set higher?I’ll show you a little experiment. For screens/windows wide enough to fit all of the top-level nav elements horizontally and have enough room left over for our logo, we detatch and float the nav to the top right. For screens/windows narrow enough that the full set of top-level nav elements would not fit on one line, we use the menu button nav pattern For screens/windows in a particular range that are wide enough to fit the top-level nav elements on a single line, we do that. I could be wrong about that, though. My hunch is that most users who zoom a lot keep their zoom set as they navigate around different pages and aren’t changing zoom settings on a site-by-site basis. Content, again, is what ends up dictating what we’re doing in the end.You could also make the text smaller and watch the same proportional adjustments occur, in the inverse.BTW: It should be noted that, unlike window resizes, which cause media queries to be re-evaluated immediately, you’ll need to reload the current page if you zoom in or out for em-based media queries to re-apply. So we deliver the menu-button nav pattern and other layout and styling appropriate for the way the text fits. Zoomed in like this, the browser no longer satisfies that query: we have fewer than 41ems to work with. With a pixel-based media query With an em-based media queryThe pixel-based media query all and (min-width:656px) still evaluates to true with the zoomed-in text and therefore creates awkwardly-wrapped nav elements.However, the em-based media query of all and (min-width: 41em) scales to the larger text size. ![]() The site looks pretty decent, however, with media queries in ems: Our site looks tolerable on a Kindle Touch. Its resolution meant that it was using our tablet-range layout, but its text was enormous, causing widespread ugliness as the pixel-width elements didn’t scale to adjust. It reports its web pixel resolution as 600×800, but its default text size is considerably larger than 16px/14pt.Our early, pixel-based media queries for our nav looked dreadful on the Kindle. For the iPhone, 1em is still approximately 16px or 14pt, and so pixel-based media queries generally behave equivalently to em-based ones (disclaimer: that’s a broad generalization).The Kindle Touch, on the other hand, has taken a different approach. An iPhone 4, for example, which has a real resolution of 640×960 and 326ppi, masquerades as 320×480 in the browser as a way to get normally-designed websites to look normally-sized and not teeny tiny. Most smartphone browsers get around this by reporting their resolution differently for purposes of the web. Ntfs for macr14 torrentThere may well be a better way to do this math, but this seems to do the trick so far.It’s been a couple months since I last checked, but depending on the browser, setting a custom font-size on the HTML or body element may or may not affect the value of 1em in media queries, even though it does change it in the rest of the CSS (I think Opera’s implementation differs from the others, or it used to at least). One thing I’ve seen in the past that might be worth noting, with regards to this part:We noted that pixel measurement and divided it by the rough baseline of 16px to arrive at our em units. Em queries certainly do pair well with fluid layouts from what I’ve seen. We ‘re cooking up ideas about how to make this better! have actually made improvements to the tablet-version nav on touch devices since I started working on this post! More to come in Nav-Land.+1 – good info here, Lyza. Thanks to the observant folks in the community who have noticed that our nav, at wider widths, has drop-down elements that are not ideal in terms of usability. Too bad! Speaking of Kindle and Stephanie Rieger, the Kindle Fire tablet’s browser is also a great cautionary tale about mistaken complacence about “standard” device screen widths like 480, here is an enlightening tweet: Food for thought, Stephanie, food for thought…P.s. If body font size does affect the value of 1em in a query, the breakpoints would likely occur at narrower places than intended.But even if the browser implementations do not still vary, perhaps the addition of em queries values are all the more reason to not override the body’s font-size, as the usefulness of a math helper (like the old 62.
