I was looking into this a few years back. There seem to be 2 approaches commonly used to provide a 'best-guess':. User Agent Detection This is where you check what the client is claiming to be. It's not perfect, since I believe it is fairly easy for this property to be altered accidentally or otherwise.
Using Client Capabilities As you can imagine, a more pragmatic approach - allows you to cater to the known physical capability of the client. However this is not ideal either, since higher and higher pixel densities in modern devices give you a misleading result: appearing that you have more 'room' than you actually do. Plus different browsers may expose their capabilities through different means.
Just to clarify: by "higher pixel density" you mean that the DPI is higher, so the pixels are smaller and packed tighter together which can lead to major usability issues on mobile devices even if the device has a "laptop resolution" of say pixels wide.
Exactly: so a device such as a tablet may report that it is "px wide" for example, and deceive a 'traditional' web developer like me into thinking that this translates to having the width of a typical office monitor, which may also report to be px wide.

Community and Moderator guidelines for escalating issues via new response….You are coding some great theme or plugin and you get to a point where you realize that you want something to change ONLY for mobile devices.
It happens. So I sought out a simple way to detect the user was on a mobile device, then swap out the class name of an element. Seems simple enough, right? Because you could use media queries instead. So in order to only target mobile browsers, I stumbled on this great script from abeautifulsite.
So one way we can do this is to trick our browser into acting like a mobile browser. It really makes it easy to test, and it incorporates Live Reload. Honestly… slow clap for IE11 folks. Firefox has an excellent DevTools editor, but NO user agent switching in it.
This all depends on exactly what you are trying to accomplish. For me, I wanted to show a link for desktop browsers and a slightly different link for mobile devices.
One should show up on a mobile device, the other on desktops:. Then, of course, I have a. I already have the isMobile script from above.There is a simple way to handle that.

There are two variables at play here- the distance traveled by the user's finger on the x or y-axis from touchstart to touchendand, the time it took. Based on these two factors, we can decide whether that action qualifies as a swipe and in what direction. With that said, lets put ideas into action and see how to go about detecting a swipe right from left to right. Once we can do that, detecting swipe in the other 3 directions is pretty much identical.waybackinsta360.pw SSR Refresh Tokens
For this exercise we'll stipulate that a right swipe has occurred when the user has moved his finger across the touch surface a minimum of px horizontally in ms or less from left to right. Furthermore, there should be no more than px traveled vertically, to avoid "false positives" whereby the user swipes diagonally across, which we don't want to qualify as a swipe right.
Inside touchendwe check that the dist traveled from touchstart to touchend is a positive number above the specified threshold value ie:since in a right swipe, that dist should always be positive based on the equation used versus negative for a left swipe. At the same time, we make sure any vertical lateral movement traveled is less than px to weed out diagonal swipes.
Since the vertical movement can occur either above the starting touch point or below, we use Math. Now that we got right swipe down, lets create a more generic function that detects swiping in either of the 4 directions left, right, up, or down :. The function parameter " swipedir " tells you the type of swipe that was just made with five possible values: " none ", " left ", " right ", " top ", or " down ".
The below uses the swipedetect function to show a "left", "right", "top", or "down" background image overlaid on top of a default background image depending on the swipe that has just occurred:. We bind swipedetect to " touchsurface2 ", and whenever a valid swipe has occurred inside it, we change the " inner " DIV's background image accordingly to reflect the type of swipe that has just occurred.
