I would like to use flexbox in Polymer to create tables out of divs.
But the main problem is that by "cells" squish because of the content inside it when I change the size of the puter div. In the example below, try resizing the browser window. How do I get it to obey the size defined by flex as first priority while still wrapping text?
<!doctype html>
<html>
<head>
<script src='../bower_components/webcomponentsjs/webcomponents-lite.js'></script>
<link rel='import' href='../bower_components/iron-flex-layout/iron-flex-layout-classes.html'>
</head>
<body unresolved>
<dom-module id='base-page'>
<style include='iron-flex iron-flex-alignment'>
.border {
border: 1px solid red;
}
</style>
<template>
<div class='vertical layout' style='width:50%'>
<div class='horizontal layout'>
<div class='flex border'>Short</div>
<div class='flex border'>This is a muuuuuuuuuuuuuuuuuch longer text</div>
<div class='flex border'>And this ie medium</div>
</div>
<div class='horizontal layout'>
<div class='flex border'>e</div>
<div class='flex border'>e</div>
<div class='flex border'>e</div>
</div>
</div>
</template>
</dom-module>
<script>
HTMLImports.whenReady(function() {Polymer({
is: 'base-page'
});});
</script>
<base-page></base-page>
</body>
Thanks
Cheers
Adding this to your border class should solve the issue.

I am making an carousel by using owl Carousel. but it doesn't shows anything
this is my html code:
#{
Layout= null;
}
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="~/css/bootstrap.css">
<link href="~/css/owl.carousel.css" rel="stylesheet" />
</head>
<body>
<div class="container">
<div class="owl-carousel">
<div class="bg-info">Content 1</div>
<div class="bg-danger">Content 2</div>
<div class="bg-dark">Content 3</div>
<div class="bg-warning">Content 4</div>
<div class="bg-white">Content 5</div>
<div class="bg-success">Content 6</div>
<div class="bg-secondary">Content 7</div>
<div class="bg-dark">Content 8</div>
</div>
</div>
<script src="~/js/jquery-1.11.1.min.js"></script>
<script src="~/js/owl.carousel.js"></script>
<script src="~/js/bootstrap.js"></script>
<script>
$(document).ready(function () {
$("owl-carousel").owlCarousel();
})
</script>
</body>
</html>
but it shows my nothing and the page is completely blank
why doesn't it show anything?
Errors inside the initialization script and any options added. Must be in that way:
<script>
$(document).ready(function () {
$('.owl-carousel').owlCarousel({
loop:true,
margin:10,
nav:true,
responsive:{
0 {items:1},
600:{items:3},
1000:{items:5}
}
});
});
</script>
It is written in document that "The grid is by default center aligned.".
However, the following code does not center the cell:
<html>
<head>
<link href="https://unpkg.com/material-components-web#latest/dist/material-components-web.min.css" rel="stylesheet">
<script src="https://unpkg.com/material-components-web#latest/dist/material-components-web.min.js"></script>

<body>
<div class="mdc-layout-grid">

<div class="mdc-layout-grid__cell mdc-layout-grid__cell--span-4">
<div class="mdc-card my-card">
<div class="my-card__media mdc-card__media mdc-card__media--16-9" style="background-image: url('image.png');">
</div>
</div>
</div>
</div>
</div>
</body>
</html>
The grid is by default center aligned
Yes, it is. The grid itself is centered (the red border), check below example. I think it is what a grid suppose to be. It define tiles and let you put component on it, so it is called grid.
<html>
<head>
<link href="https://unpkg.com/material-components-web#latest/dist/material-components-web.min.css" rel="stylesheet">
<script src="https://unpkg.com/material-components-web#latest/dist/material-components-web.min.js"></script>
<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
<body>
<div class="mdc-layout-grid" style="width: 512px; border:2px solid red;">
<div class="mdc-layout-grid__inner">
<div class="mdc-layout-grid__cell mdc-layout-grid__cell--span-8">
<div class="mdc-card my-card">
<div class="my-card__media mdc-card__media mdc-card__media--16-9" style="background-color: green">
</div>
</div>
</div>
</div>
</div>
</body>
</html>
If you really want a cell center aligned inside a grid layout, let the cell span across all columns.
We are not sure what is going to be put on the grid, or how you want to organize the content, otherwise we may suggest other component that might fit your needs.

This JSBin doesn't render its contents. It does not display:
its header section — the <paper-toolbar> text (i.e., "Header") or
its content panel section — the <div> element (i.e., "Content goes here...").
What am I doing wrong? Please provide a working JSBin example.
Note: Per this link, <paper-header-panel> requires host to have a height.

The changes:
webcomponents from rawgit instead of bower_components
<span class="title"> to make header visible
style="width:100%; height: 100%;" on element to see its content

Here is the minimum markup necessary to answer the question:
http://jsbin.com/jocinasovo/edit?html,output
Changes
Added style using :host
Only need height not width
No need to switch from bower_components (per this link) to rawgit CDN
No need for .flex class on <paper-header-panel>
Note: Per this link, <paper-header-panel> requires host to have a height.

Why are these two snippets different?
The first snippet works as expected
The second is just a copy of the contents of the body tag placed into a custom element called my-header and my-header is inserted into the body tag
The second one is not honoring the height of the body tag using fullbleed layout vertical.

You just need to add the height to your element and core-header-panel
<style>
:host, core-header-panel {
height: 100%;
}

Consider this polymer-element
<polymer-element name="my-card" attributes="title content">
<template>
<div style="padding:20px; max-width:600px; margin:50px; margin-bottom:0px" on-tap={{cardTapped}}>
<paper-shadow z="1">
<div class="row">
<div class="col-xs-12" style="margin-top:-20px"><h2>{{title}}</h2></div>
</div>
<hr/>
<div class="row">
<div class="col-xs-12">{{content}}</p></div>
</div>
<paper-ripple fit></paper-ripple>
</paper-shadow>
</div>
</template>
<script>
Polymer({
cardTapped: function(){
alert('tapped!');
}
});
</script>
</polymer-element>
this is how I am using it
<my-card content="this is a test body" title="Here is a nice Title"></my-card>
it works but when I use html in the content attribute like
<my-card content="this is a test body <p>with paragraphs</p>" title="Here is a nice Title"></my-card>
they are handled like text, is there any way to pass HTML code to attribute and embed it in polymer-template
I think what you actually want is to use the <content></content> insertion point within your <template>, rather than creating an attribute named content and using variable interpolation.
Here's an example:
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Polymer Demo</title>
</head>
<body>
<script src="//www.polymer-project.org/platform.js"></script>
<link rel="import" href="//www.polymer-project.org/components/polymer/polymer.html">
<link rel="import" href="//www.polymer-project.org/components/paper-shadow/paper-shadow.html">
<link rel="import" href="//www.polymer-project.org/components/paper-ripple/paper-ripple.html">
<polymer-element name="my-card" attributes="title">
<template>
<div style="padding:20px; max-width:600px; margin:50px; margin-bottom:0px" on-tap={{cardTapped}}>
<paper-shadow z="1">
<div class="row">
<div class="col-xs-12" style="margin-top:-20px">
<h2>{{title}}</h2>
</div>
</div>
<hr/>
<div class="row">
<div class="col-xs-12">
<content></content>
</div>
</div>
<paper-ripple fit></paper-ripple>
</paper-shadow>
</div>
</template>
<script>
Polymer({
cardTapped: function(e) {
console.log('tapped!', e);
}
});
</script>
</polymer-element>
<my-card title="Here is a nice Title">
this is a test body <p>with paragraphs</p>
</my-card>
</body>
</html>
