I am using b-tooltip tags of BootstrapVue to show information. I want to increase the width of b-tooltip (for long text message), text alignment, etc . How can i do it (basically how can i style it)?
<b-button id="tooltip-target-1">
Hover Me
</b-button>
<b-tooltip target="tooltip-target-1" triggers="hover">
I am tooltip <b>component</b> content!
</b-tooltip>
If you're using SCSS in your project, then the easiest way for a global solution would be to modify the SCSS variables to your liking.
If you want to only apply styles to a specific tooltip, or apply something there isn't a variable for. You can use the custom-class prop on b-tooltip to supply it with a custom class, which allows you to style it to your liking.
If you're placing this CSS in a scoped style tag <style scoped> you will need to use a deep selector to target the subcomponents such as .tooltip-inner.
new Vue({
el: '#app',
})
.custom-tooltip > .tooltip-inner{
/* Removes the default max-width */
max-width: none;
/* Apply whatever other styles you want */
font-size: 150%;
padding: 10px;
}
/* This styling is just for the example */
#app {
display: flex;
height: 100vh;
width: 100vw;
align-items: center;
justify-content: center;
}
<link href="https://unpkg.com/bootstrap#4.4.1/dist/css/bootstrap.min.css" rel="stylesheet" />

<div id="app">
<div>
<b-button id="tooltip-target-1">
Hover Me
</b-button>
<!-- Use the variant prop to use your theme colors -->
<!-- If you want a custom color, you can use CSS -->
<b-tooltip target="tooltip-target-1" variant="primary" custom-class="custom-tooltip" triggers="click">
I am tooltip <b>component</b> content!
</b-tooltip>
</div>
</div>
The trick to change styles of bootstrapvue tooltip.
<style>
.tooltip-inner {
max-width: 800px;
}
</style>
Don't use scoped in style because the component render the html of tooltip outside of app so if you put scoped your css will not work.

I have using Nuxt.js and Vuetify.js in my project.
I need to adjust v-divider width, so I tried to write css in my code.
But it didn't work.
Does anyone teach me how to change v-divider width in Vuetify components?
<template>
<divider class="test"/>
</template>
<style lang="scss" scoped>
.test{ width:100px}
</style>
vuetify <v-divider> uses border properties. So instead of width you should specify borders.
const opts = {}
Vue.use(Vuetify)
new Vue ({
el: '#app',
vuetify: new Vuetify(opts),
})
.test {
border-width: 4px !important;
border-color: black !important;
height: 100%;
}
body, .container, html {
width:100%;
height: 100%;
}
<link href="https://cdn.jsdelivr.net/npm/vuetify/dist/vuetify.min.css" rel="stylesheet">
<div id="app" class="container">
<v-app>
<v-divider class="test" vertical></v-divider>
</v-app>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src="https://cdn.jsdelivr.net/npm/vuetify/dist/vuetify.js"></script>
Just a typo of <divider/> instead of <v-divider/>.
Alternatively (and not really recommended), you can set the width by specifying the width attribute of <v-divider/> since it uses <hr/> element. However, this approach seems to be deprecated and the best approach is to style it using css.
<v-divider width="100"/>
I am using vuejs with vuetify a material design support for vuejs, but I am confused as to how I can add custom css styles to material design without breaking a convention of the material design itself.
It is like bootstrap where we can call .row{} and override the styling or does it differ in some ways.
I don't think there're many differences from bootstrap since vuetify will automatically add necessary class names for you. Suppose you want to override the background color of the following template.
<v-layout row justify-space-around></v-layout>
Just override it with .row
.row {
background: #123456;
}
Check the sample below.
new Vue({ el: '#app' })
.row {
background: #123456;
}
.theme--dark {
width: 400px;
}
.card__text {
font-weight: 800;
}
<script src="https://unpkg.com/vue/dist/vue.min.js"></script>
<script src="https://unpkg.com/vuetify/dist/vuetify.js"></script>
<link href="https://unpkg.com/vuetify/dist/vuetify.min.css" rel="stylesheet">
<div id="app">
<v-app>
<main>
<v-layout row justify-space-around>
<v-card dark class="primary">
<v-card-text>one</v-card-text>
</v-card>
</v-layout>
</main>
</v-app>
</div>
Please notice that - was converted to __ (e.g. v-card-text) and theme-- was prepended to the theme's name (e.g. dark).
With reference to this plunker:

I have the same css specified in the styles.css file, and in the src/app.ts file.
If I comment in the css in styles.css and comment out the css in src/app.ts, it works.
styles.css:
/* If these are commented in, and the ones in src/app.ts are
* commented out, the three items are spaced appropriately. */
/***
md-toolbar-row {
justify-content: space-between;
}
md-toolbar {
justify-content: space-between;
}
***/
If I comment out the css in styles.css and comment in the css in src/app.ts, it fails.
src/app.ts:
#Component({
selector: 'my-app',
template: `
<div>
<h2>Hello {{name}}</h2>
<md-toolbar color="primary">
<span><md-icon>mood</md-icon></span>
<span>Yay, Material in Angular 2!</span>
<button md-icon-button>
<md-icon>more_vert</md-icon>
</button>
</md-toolbar>
</div>
`,
// If these are commented in, and the ones in style.css are
// commented out, the three items are scrunched together.
/***/
styles: [
`md-toolbar-row {
justify-content: space-between;
}`,
`md-toolbar {
justify-content: space-between;
}`
]
/***/
})
export class App {
name:string;
constructor() {
this.name = `Angular! v${VERSION.full}`
}
}
I'm having trouble visualizing the difference between defining the css for the whole application, and for the specific component. Can someone tell me what's going on?
=================================
#bryan60 and #Steveland83 seem to indicate that the problem lies somewhere in the view encapsulation. And upon further investigation, it does in a sense.
If you look at the code below, you will see that the styles for md-toolbar and md-toolbar-row have an attribute attached. But the html for md-toolbar and md-toolbar-row does not match. Only md-toolbar has the attribute attached. md-toolbar-row doesn't. I have marked the relevant four lines with >>>>>.
So that's the problem but:
1. Do I report it to the material design people as an error?
2. Is there some workaround I can use today?
<html>
<head>
:
<script src="config.js"></script>
<script>
System.import('app')
.catch(console.error.bind(console));
</script>
<link href="https://rawgit.com/angular/material2-builds/master/prebuilt-themes/indigo-pink.css" rel="stylesheet">

}
</style>

One of the Angular features is View Encapsulation which basically means that you can define styles scoped only to a specific component without affecting any other components.
By default styles are scoped only for the component they are referenced in, but you can choose to override that to make them available globally by setting your components encapsulation to None.
E.g.
import { Component, ViewEncapsulation } from '#angular/core';
#Component({
selector: 'component-that-shares-styles',
templateUrl: './component-that-shares-styles.component.html',
styleUrls: ['./component-that-shares-styles.component.scss'],
encapsulation: ViewEncapsulation.None // <-- Set encapsulation here
})
*Note that you will need to import ViewEncapsulation from #angular/core
Okay, with help from #Steveland83 and #bryon60, I came to a definite answer. The Material Design people are aware of this problem. They have made a writeup.
https://github.com/angular/material2/blob/master/guides/customizing-component-styles.md
Here's their summary:
Styling other components
If your component has view encapsulation turned on (default), your component styles will only
affect the top level children in your template. HTML elements belonging to child components cannot
be targeted by your component styles unless you do one of the following:
Add the overriding style to you global stylesheet. Scope the selectors so that it only affects
the specific elements you need it to.
Turn view encapsulation off on your component. If you do this, be sure to scope your styles
appropriately, or else you may end up incidentally targeting other components elswhere in your
application.
Use a deprecated shadow-piercing descendant combinator to force styles to apply to all the child
elements. Read more about this deprecated solution in the
Angular documentation.
I don't want to use global css, or a deprecated solution. I guess I will style with classes, and not elements. If someone has a better idea, tell me!
I am trying to style my child components. Isit wrong to put the style in a parent component? It appears that does not work.
I put the style for .card-page in the top level element (containing expenses-module where I use it)
<dom-module id="expenses-app">
<template>
<style>
...
.card-page {
display: block;
width: 100%;
}
</style>
<app-drawer-layout>
<app-header-layout>
...
<iron-pages selected="{{routeData.view}}" attr-for-selected="name">
<dashboard-module name="dashboard" route="{{subroute}}"></dashboard-module>
<expenses-module name="expenses" route="{{subroute}}"></expenses-module>
<settings-module name="settings" route="{{subroute}}"></settings-module>
</iron-pages>
</app-header-layout>
</app-drawer-layout>
</template>
In expenses module,
<paper-card heading="Expenses" class="card-page">...
</paper-card>
Seems like if I move the styles into expenses-module it works.
You cannot directly style elements inside custom element from their parents like that, because Polymer processes the style within <dom-module> and will apply styles only to direct child members. It will not descend into child custom elements.
In other words, standard CSS selectors will only work within the scope of the declaring component. Both in Shadow and Shady DOM.
For your styles to work with nested elements, you should use CSS mixins and properties. All PolymerElements and many 3rd party elements will come with such styling extension points. The naming usually follow the convention, where the main mixin is called same as the element itself. Additionally, there may be more specific mixins and properties, which style only parts of the element. <paper-card> docs for example lists --paper-card mixin, --paper-card-content mixin, --paper-card-header-color and more.
If you want to better control the styling of elements you use, you would want to create your own CSS mixins/properties and #apply() them to selected elements. See how in the example below --my-elem-card-page applies only to one of the two paper cards.

I've been using Polymer for a website redesign. I want to display an image that is bound to an element as a background-image. A fairly simple task, but unfortunately I'm having some issues.
I made a running sample of the code for easy testing: click me.
<polymer-element name="album-card" attributes="image">
<template>
<style>
:host{
display: block;
position: relative;
background-color: #99182c;
width: 200px;
}
.description{
padding: 10px;
color: white;
}
.circular{
width: 200px;
height: 200px;
background: url({{image}}) no-repeat;
background-color:green;
}
</style><link rel="stylesheet" href="default_styles.css">
<paper-shadow z="{{shadowValue}}" animated="true"></paper-shadow>
<div class="album-header" vertical layout>
<paper-ripple class="recenteringTouch" fit></paper-ripple>
<div class="circular">
<!--<img src="{{image}}" />--><!-- this does work -->
</div>
<div class="description">
<content select="h2"></content>
<content select="h4"></content>
</div>
</div>
</template>
<script>
Polymer('album-card');
</script>
</polymer-element>
The issue is in the css styling. For some reason the image doesn't diplay in the following line: background: url({{image}}) no-repeat;. However, when using {{image}} in the body somewhere else (in the <div class="circular">, the image does display.
Replacing the {{image}} inside the styling with the direct link also works.
What am I doing wrong?
This looks like a bug. The {{}} are being interrupted literally instead of being parsed by the template engine. Replacing them with [[]] one time bindings works: http://jsbin.com/yocokire/4/edit
However, you should avoi using data-binding inside of <style> if possible (see https://github.com/Polymer/polymer/issues/270#issuecomment-24683309). There are perforamnce concerns and issues under the polyfill. Instead, use a style attribute on the element and do your binding there: http://jsbin.com/riqizige/1/edit
