A lot of blogs and websites that have a wide range of users tend to have buttons or images that change the text size for easier readability. There are libraries out there that do this, but in many cases it is likely overkill. Simplicity is generally better where possible. Alright let's see our options for using the resizeText function. Here's a simple example of this all put together.
This works flawlessly on at least IE, Firefox, Opera, and Safari others not fully tested, please give feedback :. Eric Wendelin is a software engineer for Sun Microsystems.

You've probably heard the talk around the water cooler about how promises are the future. All of the cool kids are using them, but you don't see what makes them so special. Can't you just use a callback? What's the big deal?

I decided to release this Are there major browsers that are incapable of increasing page text size?
This method actually does work for links and stuff, but my site is a bad example because there is hacky stuff in place preventing certain nodes from being resized.

There may also be large incompatibilities between implementations and the behavior may change in the future. The non-standard zoom CSS property can be used to control the magnification level of an element. However, unlike CSS Transforms, zoom affects the layout size of the element.

Yet if we still want to scale elements for any reason, below is a thorough analysis of different methods for doing that. The first word which comes up when we talk about size changing is zoom.
The GIF below shows what we get with zoom approach applied to the menu element. I created a switcher which allows selecting different sizes and applies an appropriate zoom level:. The menu goes outside visible area because we cannot programmatically increase viewport width with zoom nor we can wrap the menu because of the requirement.
We can get largely the same effect with transform: scale as we got with zoom. Except, transform is more widely supported by browsers. Instead of zooming or scaling, we could use rem as the sizing unit for all elements on the page. This is a fairly good solution, but not quite perfect. When we go up in size, the media queries should adjust accordingly so that the effect at the same place would happen before the size change, relative to the content.
Chrome understands that zooming actually does change the viewport. The larger the zoom, the narrower the viewport. Meaning that our media queries will actually take effect like we expect and need them to. One way to achieve this without relying on native zoom, because there is no way for us to access that for our on on-page controls as required by AA is to somehow update the media query values every time we switch the font size.
We should update that breakpoint to px to compensate for the new size. Try to update media query from px to rem in this Pen and see that nothing changes. That is because, according to standard s, both rem and em units in media queries are calculated based on the initial value of html element font-size which is normally 16px and can vary. Relative units in media queries are based on the initial value, which means that units are never based on results of declarations.
We can use power of Sass mixin s to get around this though! So if we have n breakpoints and m sizes, we will generate n times m media query rules, and that will cover all possible cases and will give us desired ability to use increased media queries when the font size is increased. All code inside the media query gets additional level of specificity because it goes inside html. So if we go with the mobile first approach and use, for example.
To avoid this we can create the same mixin for mobile and wrap with our mixins not only desktop but also mobile CSS code. That will balance specificity. Other ways are to handle every special case with an individual approach by artificially increasing specificity, or creating mixin with desired functionality no margin in our example and putting it not for mobile only but also into every breakpoint code. That is a tough one. Personally, I try to avoid the features of a framework which depends on the screen width.
The main one which can be often missed is a grid system, but with the rise of flexbox and grid, I do not see it to be an issue anymore.This tutorial shows you how to customize the way users interact with your map. Learn to control whether your users can zoom and pan the map, and also whether the user's page scrolling actions take priority over the map's zooming and panning. When a user scrolls a page that contains a map, the scrolling action can unintentionally cause the map to zoom.
The code also sets a specific latitude, longitude and zoom level. Note: The gestureHandling property is set to cooperative by default on pages that are scrollable.
This means that the map does not change when the user scrolls the page on touchscreen or mobile applications. Read more about gesture handling below. The example below disables zoom and pan on the map for desktop, touchscreen, and mobile devices. In your index.
Save and open the index. Note: You can also disable zoom by setting the minZoom and maxZoom to the same value.
This also disables scroll on the map. This demo does not prevent the map from panning or zooming on page scroll. The code above sets the gestureHandling property to greedy for touchscreen and mobile devices, to allow users to pan the map up or down, left or right when the user swipes drags on the screen. In other words, both a one-finger swipe and two-finger swipe can cause the map to pan. This section defines terminology that's relevant to this tutorial, and various actions that users perform to interact with a map.
See the guide to events and the reference for more information. The fullscreen control is visible by default on mobile devices, so users can easily enlarge the map.

When the map is in fullscreen mode, users can pan the map using one or two fingers. Note: iOS doesn't support the fullscreen feature. The fullscreen control is therefore not visible on iOS devices. The following restrictions and limitations apply to the behavior made available in the gestureHandling option:. Touch-sensitive devices only: The gestureHandling options apply only if the user is viewing the page on a device that supports a touch interface.
Note: An exception to this limitation is when viewing maps that have gestureHandling set to none on desktop devices. The none option disables panning and pinching on the map for mobile devices, and dragging of the map on desktop devices.

Despite privacy concernshundreds of thousands of people around the world have recently downloaded the video conferencing app.
People are using Zoom to connect with coworkers for video meetings while working from home. Educators are using Zoom to create presentations to teach their students thanks, in part, to Zoom making it free to schools. Teens are even using Zoom to video chat and hang out with friends. One thing everyone experimenting with Zoom for the first time seems to love is its virtual background feature. It allows users to swap out their real-life background with an image or video while streaming with friends, family, and coworkers — no green screen required.
Download the Zoom Mac or Windows app. Open the application, sign in, click your profile picture, followed by the Settings link in the drop-down menu.
Navigate to the Virtual Background tab. If you do not see this tab, log in to the Zoom website, go to Meeting Settings, and make sure Virtual Background button is toggled on under the Meeting tab. In the Virtual Background tab, users can choose from pre-installed backgrounds or upload their own photos or videos.
If you do not have a green screen, Zoom recommends streaming from a location with a solid background color. A screenshot of the Zoom's iOS interface. Click the "More" tab on the bottom right to access Virtual Backgrounds. If you have an older computer or mobile device and are experiencing issues getting Zoom virtual backgrounds up and running, check out the system requirements here to see if you can enable the virtual background feature.
It's up to you to decide which exotic locale or classic movie scene to use as your background image. We're using cookies to improve your experience. Click Here to find out more. Tech Like Follow.
