I have been working on a Bottom Tab Navigator and try to make tab bar items being highlighted with a circle shape around the icon when they are selected. I tried to set the height and width inside tabBarItemStyle, however, only height changes while width does not change. Is there something else I missed? How can I set the width so that the highlighted part is in a circle shape?
Here is a demo of the tab bar I am working on.

The issue is because the width value is being overridden by the containers flexbox property.
A quick easy fix is to use the maxWidth property instead of width in tabBarItemStyle properties.
There's a nice article here: https://mastery.games/post/the-difference-between-width-and-flex-basis/ that explains it.
I am using component based architecture and want to show bootstrap modal which gets adjusted to image height and width.
Most of the forums suggested to use height and width in percent but this will not going to help as image size can vary.
Has anyone achieved this?
There's a simple solution for this. first of all you will need to override the modal's width property (height is auto adjustable and shouldn't be a problem), the modal window uses the .modal-dialog class, so use !importent to override width
.modal-dialog {
width: fit-content !important;
}
content-box will adjust the width according to what the element contains.

I am on react native v.42 using width='100%' with images created for an iphone 7 #2x (750px width). This works properly for the iphone 7, but if I look at the images on a 7plus, they get clipped at the top and bottom. In order to prevent this, I have to save out the images for a 7plus (818px #2x).
Does anyone know how to use width='100%' and have the image scale beyond its maximum native dimensions proportionally? Changing resize mode does not work. I also don't want to use any plugins if I can help it.
I know that I can explicitly define the height and width based on the window Dimensions:
import { Dimensions } from 'react-native'
const { height, width } = Dimensions.get('window')
export {
height as deviceHeight,
width as deviceWidth,
}
and use a ratio calculation for the height, but I am looking for a way to not have to declare dimensions for the height (essentially a height: auto).
Theres a few things you can try.
Try telling the image to cover the screen
resizeMode: 'cover'
Because this is all flexbox layout you can use align-self to tell the child to stretch
alignSelf: 'stretch'
If neither of these work for you.. Another alternative that I've done before is to remove the static size so that it will grow naturally (by specifying null for the width and height)
width: null,
height: null

ExtJs grid has a property reserveScrollbar which reserves space for scroll bar. I've a window with layout : 'absolute' which is the container for grid.
Now the problem is, the grid doesn't reserve space for scroll bar. Many forum say the container should use layout:'fit' to make it work. However I want it to be layout : 'absolute' only.
I set exact width and height for the grid and for its columns. I expect grid to reserve space from its width.(Leaving this to Sencha).
Is there any fix for this?
You could place the grid inside a container or panel that has layout: 'fit'. The container can then be within a window that has layout: 'absolute'. You can then set the height and width for the container instead of the grid.

I have fitVids working on my site. However, I'm wondering if it is possible to prevent fitVids from enlarging a video beyond its defined height/width. For example, if a video is 600px wide, but the container is 800px, fitVids enlarges the video to 800px wide and it is blurry. I'd only like fitVids to shrink the video when the container shrinks for smaller devices. Is that possible?
jQuery(document).ready(function(){
// Target your .container, .wrapper, .post, etc.
$("#thing-with-videos").fitVids();
});
helgatheviking's solution constrains the width of the video, but not the height. If your container is wider than the video, you end up with a really tall, letter-boxed video. The height is easy to fix, using the same technique to constrain the width. But, there's a third variable.
fitVids wraps the iframe in a div, with the class "fluid-width-video-wrapper", and sets padding-top equal to the aspect ratio of the video. Even if height and width are constrained, the fluid-width-video-wrapper will still be as tall as the video could be, if it didn't have a max-height. So, you end up with a bunch of white-space below the video.
Rather than set all three values (width, height, and padding), you can simplify everything by wrapping the iframe in a div with a max-width, before initializing fitvids.
var vidFrame = $('#fitvids_container').find('iframe');
var vidWidth = vidFrame.attr('width');
if (typeof vidWidth !== undefined) {
// Wrap the iframe in a Div with max-width defined
vidFrame.wrap('<div style="max-width:' + vidWidth + 'px;"></div>');
}
// Initialize fitVids
$('#fitvids_container').fitVids();
Like helgatheviking's solution, if you have more than one video per page, you'll have to calculate the max-width for each video.
One option is to make a small modification to the fitvids code which checks for a data-maxwidth attribute and if found wraps a div with a max-width style to limit the resized iframe.
This allows each videos max width behaviour to be specified independently.
For example. Add the data-maxwidth attribute to the iframe.
<iframe width="560" height="315" data-maxwidth="560" src="https://www.youtube.com/embed/L-UIiRlydow" frameborder="0" allowfullscreen=""></iframe>
Then add the following code snippet to the fitvids.js file, at the end of the $allVideos.each function, just after $this.removeAttr('height').removeAttr('width');
if ($this.data("maxwidth"))
$this.parent('.fluid-width-video-wrapper').wrap('<div></div>').parent().css('max-width', $this.data("maxwidth"));
It simple!
Assuming "thing-with-videos" is the ID of the wrapper on which you are calling .fitvids()
So just set the max width css property for this container.
Example:
#thing-with-videos {
max-width: 600px;
margin: 0px auto;
}
This wont let your video width go beyond 600px. Margin property will center your video container.

Set your custom width in the "Video container width" textbox and watch the preview!

Patrick's answer eventually made me realize that I could put a max-width on the iframe itself.
#fitvids_container {
max-width: 600px;
}
#fitvids_container iframe {
max-width: 500px;
}
However, if you were using a lot of videos (of different sizes), you might want to do this dynamically. With jQuery we can get the width from the iframe attribute and make it a max-width style rule. This only works if you've included the width attribute in your embed code though. This is a single example, but could be adapted to an .each() loop or at least renaming the container div to a class.
var width = $('#fitvids_container').find('iframe').attr('width');
if (typeof width !== undefined) {
$('#fitvids_container').find('iframe').css('maxWidth', width + 'px');
}
