What is alternative of DIV in NativeScript?
How to use block inline with content inside?
Within Browser the behaviour div is determined by display CSS attribute.
For example, by default it's block and vertical which is similar to StackLayout with orientation set to vertical. When you make it inline, that's more like a horizontal layout, so again could be StackLayout with orientation set to horizontal.
There is again flex, we also have an equivalent in NativeScript, the FlexboxLayout. If you set position to absolute on div, it can be compared to AbsoluteLayout in NativeScript.
There is also GridLayout, WrapLayout, and DockLayout in NativeScript that serves various purposes.
So the alternative for div here totally depends on what kind of UI / layout you are looking for / how exactly you have styled the div on web.
If you are beginner, https://www.nslayouts.com/ is a good start to know all about NativeScript layouts.
I am in the process of converting some animated GIF animated spinners to animated SVG for better/sharper display on Hi-DPI screens.
One issue I've run into is that when a user starts navigating to another page, an animated GIF continues animating but an animated SVG freezes. So if I want to have an animation that shows the next page loading, I can't find a way to get away from using GIFs.
Is there a way to have SVG animations continue animating during page navigation?
(I am specifically using Chrome for this, because if it doesn't work in Chrome I can't use it.)
EDIT: The SVG uses SMIL to do the animation.
UPDATE
After receiving no responses on this, I can't find a way to keep SVG animations animating during navigation, so I have adopted a different approach, which is to use CSS animations.
CSS animations continue animating even after navigation starts. They are a little harder to deal with, as far as inserting into a page and integrating with other elements, but they do the trick.

On mobile, buttons are skipping around when you scroll. I think the issue may have something to do with Slick Carousel.
How would you troubleshoot an issue like this?
Looks like Slick is adjusting the height of your slideshow div according to the device you are using. It doesn't know to adjust the height for your second button.
The height adjustment to the div is usually done via Javascript. You can adjust the JS code to suit your buttons or put some CSS media queries in place to override what the JS is putting on your div.
I am trying to build a slider filter, which enables users to select a numerical range of a filter. I want to add a histogram image(i.e. svg) as a background of the slider. Currently I am considering d3.js or jQuery Sparkline, and a jQuery slider or HTML5 native slider element. Can someone give any suggestions on Javascript library?
Compare:
<input type="range">: native, does not require an extra library.
jQuery slider: Cross-browser, can have much control over the appearance.
Sparkline: a jQuery plugin, even more control (never use it, can't tell)
The most important thing is, depending how you are using it, choose the one that best fit your purpose. Sometimes a simple jQuery slider is enough, but in some case a plugin might do even more.
I have a dojo animation object of about 15 images. I'm also using dojo.fx.chain to link them all together.
Right before I create all my dojo.fadeIn's and dojo.fadeOut's I added in some basic javascript to preload each image.
My question is: Am I doing this the hard way or is there some function/attr I can set in the animation object to do this?
I do not think there is a predefined method in dojo to preload these images for your animation.
I guess you are listening image.onload and image.onerror events to preload images, it is a common method. If you feel it is too difficult and hard to control, you can try a simple clean css way that is to put an invisible div into your page and set background images with these animation images. When the page load, the images are automatically loaded.
dojo Animations are not specifically geared around images, they work on an abstract level and may operate on DOM nodes. So, there's no built-in support for IMG nodes specifically.
There is dojox.image.preload (http://api.dojotoolkit.org/jsdoc/HEAD/dojox.image.preload) which will do the work virsir suggested of loading images into an offscreen div, but it does not (currently) arrange an onLoad event hook for you to detect when they're loaded and thus play your animation.
I imagine you could use preload()'s return value and use it to hook into onLoad, but that's an exercise for the reader. Have a look at the source code, dojox/image/_base.js.
