why does the main app scss file in ionic 4 not work? - ionic-framework

I've been working on an ionic app, I've come to do some styling on it and I'm having issues with app.scss.
According to the ionic documents I should be able to use app.scss for app-wide styles such as the toolbar etc. but nothing happens when I try to style anything from this file, it's like it's not being included in the build?
The initial project was done by creating the app in CLI with the sidebar menu option as the template and all the scss files work fine in the individual components.
Any idea why the app.scss file isn't working? I've inspected elements I've tried to style and they are not being picked up at all.
An example:
ion-title {
background: red;
}
this doesn't work, the toolbar background doesn't change, but it does through chrome inspector.
I have tried this in global.scss too and still nothing, funny thing is if I apply a display:none to all elements it works:
* {
display: none;
}
it just doesn't seem to want to style individual elements like the "ion-title"
UPDATE:
There seems to be a bug in ionic 4, the styleUrls won't accept me adding ../app.scss , it throws an error, but I can include ../app.css so I'm just going to auto-compile the scss to css.
I can then include the app.css file in each component and it's working!


In Ionic 4, global styles are saved by default in src/app/global.scss
If this is an Angular project that you are converting from an Ionic 3 template, you must add a reference to your global scss file in your angular.json file in under projects/app/architect/build/styles, like below
"styles": [
{
"input": "src/theme/variables.scss"
},
{
"input": "src/global.scss"
}
],
This is a change from Ionic 3 where it used to be in src/app/app.scss. If you created a project in Ionic 3 or earlier, you must move your styles into a new global.scss for them to be applied throughout the whole app

You must include the path of app.scss file in your app.component.ts like this
styleUrls: ['app.scss']
Then you will be able to use your scss file

Can I use vscode file-icons in a webview?

Is it possible to have access or use file icons inside a webview? The icons on the side of each file/folder in the explorer.
My project has a custom activity bar, where I would like to show icons for a file type, preferably using the current Icon Theme, is this possible?
I've seen that code icons can be used, injecting the css in the webview:
const codiconsUri = webview.asWebviewUri(
vscode.Uri.joinPath(extensionUri, 'node_modules', 'vscode-codicons', 'dist', 'codicon.css'),
);
Then used like this inside the webview's HTML:
<i class="codeicons codeicons-beaker"></i>
But I have not been able to find any reference about how to do this with file icons.

I have the same issue.
I notice that the error code is 401(Unauthorized) when loading the codicon.css.
But it works if I copy the codicon.css and codicon.ttf files to the other folder which is the same level as the node_modules.

Upgrading Ionic 3 - Ionic 4 CSS copy over issue

I'm working on updating an Ionic 3 application to Ionic 4. I'm having an issue with the app css not working. I copied everything within app.scss from the original application to global.scss in the new application.
When I load up the first page of the app it looks nothing like the original application. I thought this part was more or less copy/paste but I may be wrong. One thing I experimented with was a line of css I have that looks like:
ion-input.input {
margin-bottom: 0;
border: 1px solid lightgrey;
}
and changed it to
ion-input {
margin-bottom: 0;
border: 1px solid lightgrey;
}
The new application then seems to take the border into account. Is there some major css changes needed in this conversion? or am I missing something?

Yes there are major changes. Now that Ionic 4 is based on web components the insides of them are encapsulated.
This is so they can be dropped into any page and look how the developer expects it to look, rather than being messed up by the pages styles.
The web components expose certain settings that can be styled. These are listed at the end of each documentation page. For example with ion-input:
ion-input - custom css properties - Ionic Documentation

Here is a solution for the border, and here is a solution for margin. Unfortunately the reason this has to be changed in Ionic 4 is because the Shadow DOM is now being implemented. Here is more info on that. Cheers :)

Ionic 2 - Adding a background image to a page

I have just installed a new Ionic project - Ionic v2.0.0-beta.32
Im looking to add a background image to the home page of the fresh install, is there anyone that could show me how i go about this? All i can find is information for Ionic 1 and things seems quite different.
From what ive found, the image needs to be the following dimensions
2800px x 2800px
But apart from that i cant find any other tutorials.
This is my first Ionic project so be gentle
Thanks you guys

The image can be any size.
go to app/theme/app.core.scss and add the following code
ion-content{
background-image: url('img/background.jpg');
}
This is assuming that the name of your image file is background.jpg and is stored in www/img/ folder.
Hope this helps
UPDATE Ionic 3.x
Go to app/app.scss and add the following code
ion-content {
background-image: url('assets/img/background.jpg');
}
This is assuming that the name of your image file is background.jpg and is stored in assets/img folder.

For Ionic V4 they use some new switch in the scss file. This worked for me:
ion-content {
--background: url('../../assets/Welcome-screen.png') no-repeat 50% 10%;
}

In ionic 2 the background image work only if you put the img folder into the build folder. If you go to inspect on the mage url it will show you that i finding for it in build/img/bg.jpg try to put folder img into build folder.
www/build/img

Where do Images go in IONIC 2

I am just getting started with Ionic 2. I have created an img file in app inside it is a file logo.png. So I have created the following code:
css:
.getting-started {
.logo {
background-image: url(./img/logo.png);
}
}
html:
<ion-col offset-33 width-33 class="logo"><h1>Logo</h1></ion-col>
<h3>Welcome to your first Ionic app!</h3>
</ion-content>
I know the css is working, as if I toggle the background color, I get the expected results. However, I don't get any background image, just the Logo text specified. Where should I have put the image file?

EDIT: As of Ionic 2 RC 0, the correct place to put your images is in src/assets/img/ and the correct code to reference the image is <img src="assets/img/myImg.png">. Please see Ionic's change log for RC0 (specifically #28).
As of right now, using the official Drifty Co. Ionic 2 Conference App as a reference, images should be placed inside of the www/ directory.
In my current Ionic 2 app, an image is located at www/img/logo.png and it is referenced in app/pages/page_name/page_name.html as <img src='img/logo.png'> and it works like a charm.
Currently using:
ionic-angular v2.0.0-beta.6 (package.json)
ionic-native ^1.1.0 (package.json)
ionic-cli v 2.0.0-beta.25 (installed CLI)

Using Ionic 2 beta 6, I handled this with a simple gulp task. I dropped my images in app/assets/images (this path is completely arbitrary). Then, I added the following task to gulpfile.js:
gulp.task("assets", function() {
return gulp.src(["app/assets/images/*"])
.pipe(gulp.dest("www/build/images"));
});
You'll also need to update the watch and build tasks to include the new assets task in their calls to runSequence(). I don't believe the order of tasks in the sequence matters, in this case:
gulp.task("build", ["clean"], function(done) {
runSequence(
["sass", "html", "fonts", "assets", "scripts"],
function() {
buildBrowserify().on("end", done);
}
);
});
If you output your images to the same path as I did, then you would reference your images in CSS from ../images/image-name.png and in <img> tags from build/images/image-name.png. I have confirmed that these images are visible both from the browser and an Android device. I don't think it should be any different for iOS.

The assets folder is the correct folder to place any media.
The location of my image:
fyi: if you dont have the folder, just create it
src > assets > img > background.png
variables.scss
.backgroundImage {
background-image: url('../assets/img/background.png');
}
Then on the page I want to use it on:
home.html
<ion-content padding class="backgroundImage">
</ion-content>
You can also reference images the following way:
home.html
<ion-content padding class="backgroundImage">
<img src="./assets/img/background.png" width="50%" />
</ion-content>

www\lib\ionic inside ionic create one folder img
now your path
www\lib\ionic\img put your background image inside this img folder and in your
www\lib\ionic\css\ionic.css
inside ionic.css find .view-container class and past this line.
.view-container {
background: url("../img/main_bg.jpg") repeat scroll 0 0 / 100% 100%;
}

OK, so I found the answer on the IONIC forum. The images go in www/img, the paths to these is then:
url('../../img/appicon.png')
when referenced from css or html in a page folder which is in pages in app.
Hope this helps anyone in the future.

I was having same problem, I found a way, I don't know if is the best way, but it's work.
the images must go on a file sibling to build, inside folder www
www
build
img

Got the solution. Its using path relative to index.html and not template folder.
So we need use path without../
src="img/John_Williams.jpg"
This works both on browser and apk

I could not manage to make it work using a PNG file. It worked in the browser but when I build the app and deployed to a device it did not displayed.
Instead of fiddling with the Gulp file to understand what was going on, I figured out a simpler workaround :
Inline the image into your HTML (or CSS) using a Data URI.
There are many tools online such as this one that will convert your PNG to a Base64 data URI.

If your image is pool.jpg. Place it in /src/assets/img/pool.jpg
It needs to be in this directory (assets) as it is your source from where everything gets built.
Then stop your ionic serve command (Ctrl-C) or whatever you use.
Then delete EVERYTHING under www directory (it all gets rebuilt anyway).
Then restart your server by running 'ionic serve' again.
This will rebuild the directory with the images.
You can reference the image as background-image: url('../assets/img/pool.jpg');
in your code.
I am using ionic 3 and it's a shame it doesn't pick up changes in the assets directory. IONIC should look at this.

I 'm currently on ionic version 3.6 and I had to use this to work:
src="../../assets/img/myImage.jpg"
The path assets/img/myImage didn't work for me
I hope this helps

Hi Guys i found a method add images to ionic v2
Create a images folder in "www" directory (www/images/) and add your all images in this path.
Then give your image path like this
ex: for pages
src="images/logo.png"
in CSS
.ThemeColor{ background: url(/images/bg.png)};
That's it, works for me..
Thanks

Ionic tabbed slide box icons are not aligned

The icons that displayed here:
http://ionic-sarav.rhcloud.com/ionic/tabbedSlideBox/default.html#/ are working fine, though if I copy paste the entire code and copy-paste it in my index.html in my local Ionic project that I created - the icons are not aligned.
[Screenshot]
[]1
Thing is, beside index.html - I really didn't change anything, so I'm not really sure what's causing it:
The <a> tags are with text-align: center after rendering ( "computed" in Firebug )
I though the Ionic version maybe outdated/too new, but version 1.1.1 works fine vs 1.0.0 in the demo URL.
Another thing to notice is that the code in the demo:
<style>
.slider-slide h3{
color:#fff;
margin-top:10px;
};
.scroll{ height:100%;};
</style>
should make the title "Games content" white ... but it's not affecting it.
Clarifying my debugging
Checkout my plunker for example: http://plnkr.co/edit/3wLO3MNgeMOESSBRA0Vp?p=preview
( code is exactly as in the GitHub example in the link above just I played with the Ionic version to see if maybe I have an outdated version of Ionic )
In my server I did:
> I created a new Ionic project, bower.json:
"ionic": "driftyco/ionic-bower#1.1.1"
> I edited files under www
> In www/index.html - I copy pasted the content of index.html from the Plunker
> Plunker works OK, but in my server I have Icons aligned to the left vs centered
Any thoughts ?
