How to get bootstrap current screen size? - twitter-bootstrap-3

I'm able to get the current viewport by using Responsive Bootstrap Toolkit but is there a way to get current screen size as well?
For example: xs (viewport), 425 (screen size)

Sizes are noted at top of table. Note that bootstrap codes in mobile-first.

Create A view with fixed percentage of width in all orientations in React-Native

I want to create a view - that contains a Card - always with '90%' width of the window, whenever the device is vertical or horizontal, or Component is in a parent or not.
What I tried:
1 Using percentage
( width: '90%'):
It works well if I use my card separately on the main view of my screen, but when I use my card on a horizontal ScrollView with other cards I can see many cards, but I want to see only one card before scrolling.
2 Using React.Dimensions
( Dimensions.get('window').width*0.9 with some padding) :
It works perfectly when I use a card separately or even with many inside a scrollView but when I change the orientation of the screen it takes less width of the screen than '90%'.
3 Using flex basis based on this answer
Is there any better way to achieve my goal?
You might wanna look at this package https://github.com/marudy/react-native-responsive-screen
This package doesn't require any orientation change support. It's just one file actually, so you might wanna take a look at that

How to build below screen in titanium?

below i attached an app help guide screen. I am understanding how to build this screen.
If any body have idea please share here
View with semi transparent background color (backgroundColor:"rgba(0,0,0,0.5)";) and some images on top of it.
So, using images is bad. You'll need images for translations and if you do this as one image you'll need to ensure all devices are covered so your arrows point to the right element.
Minimise images == smaller app.
First thing you'll need to do is a create a blocker view -- so that's a view that will fill the screen and have a black background with opacity.
You can't apply that to the window as everything in it will be semi-transparent so:
Create a transparent Window that fills the screen.
Add to that window a view that fills the window and has opacity say 0.5 and black background
Add to the Window (not the view you just created) the other elements and button -- ideally, these should be individual graphics of the arrows, sized in such a way that you can position them based on the host element (the item they are pointing to / referring to). Use real text so you can handle translations / reduce file size.
So you'll need a way to associate each tip with a control they are anchored too, and that will ensure that regardless of the screen size, the tip will appear in the correct place.
First of all, always give a try before putting questions anywhere because it makes you learn things on your own for long time.
The easiest step for you to do this is to ask your designer to create a complete image just like that & you just have to show it on top.
If you have to show that image in different translations, then you can ask your designer to provide you required translations images.

Titanium: How to determine the screen width when using SplitView?

I'm used to using Titanium.Platform.displayCaps.platformWidth all over my app to get the width of the window.
But with SplitView on the iPad Titanium.Platform.displayCaps.platformWidth still returns the total screen size of the iPad (as it probably should).
How can I determine the actual available screen width for the app while using SplitView?
I don't mean SplitWindow BTW. This is in regards to SplitView where you can line up two different apps next to each other on the iPad
Thank you!
you can get the width your uiElement using postLayout event
var uiWidth;
myElement.addEventListener('postlayout', postlayout);
function postlayout(e){
uiWidth = e.source.rect.height;
myElement.removeEventListener('postlayout', postlayout);
}
An easy way to determine how wide a certain view is, is to use toImage() on the UI element, and then get the size.
So... when you do
console.log($.myWindow.toImage().rect.width);
You should get the width of the window. Which should be the width allocated to your app.

Leaflet map and bootstrap 3

Please have a look at http://www.bootply.com/133473.
I have at least a couple of problems and I didn't find any solution up to now...
First problem:
The leaflet map is 0px height and the next row is not in the correct position.
Second problem (but maybe it is related to the first one):
On a small device the width of the map is the full width but I'd like to have a margin and I wasn't able to get it (I tried but margin-left, margin-right and padding-left, padding-right...) and of course the text row is superimposed to the map and that's not what I want...
Looking at your bootply posting, it looks like your first problem was solved (I see the map so the height must not be 0px).
As for your second problem, it is the Bootstrap Editor that is not able to show your app on smaller screens. This problem may go away when you view your app on its own web page.

Header of a WP responsive theme won't properly remain on top at the top when scrolling; position:fixed and width:any% throws it out of whack

The WP responsive theme I'm working on:
http://www.wpexplorer.me/tetris/
I use Firebug for Firefox browser addon thingy to make changes before messing with the actual files. So if you have it or something similar, you will see that by adding position:fixed; to the #header section the header width shrinks well more than half its original size and the navigation menu is jacked up within the new shrunken space.
I have added other snippets of coding to the #header section like width:100%;, width:959px; and other percentages and pixels, which messes up the layout; especially when you resize the window down to what you would consider to be for a tablet and a mobile device - it's all out of whack. I can't get the sticky header for this theme to function or do right. Oh, I've also added z-index:200; to the #header section and margin:160px 0; to #main-content; these don't give me issues.
Adding the width: ; code to the #main-content doesn't seem to help either (which I read somewhere online that this was where the width code goes).
Anyway, does anyone know what code I need to make the header of this theme scroll up until it gets to the top of the page where it becomes sticky/static/fixed/on top (whatever the real term for it is) at all times? And, can you get it to work with the layout being in tact when the window is resized all the way down to the size of a mobile device?
Thanks.
This should work
#header-wrap{position:fixed;top:0;z-index:999;}
#pre-header{margin:20px 0 15px;width:960px;}
#main-content{margin:215px 0 30px;}
The position is fixed at the top using 0 with a z-index:999 you then need to set the width of the inner container pre-header 960px to match the rest.
You will need to setup the media queries for the other sizes you have setup. Easy, and Enjoy.
If you want the menu itself and not the social icons to become the top fixed bar without the social icons then you want to make a jquery scroll CSS change so that the #header becomes the fixed position.
It working with fixed header and social:
An illustration of it working without the social bar using a Jquery Scroll CSS change:
This is the way I would do it, I would move the menu down, and add the social icons to the menu itself. (Below is a screenshot of what I mean, the social icons are reduced to 75%)
PS. The social icons stand out to much so I would add a CSS3 Greyscale, and when the visitor hovers over them it turns on the color with a transition effect.
Hope this helps ;)
