I am newbie for polymer. I just tried to add but getting blank screen. Did I missed any script or something?
Head
<script src="bower_components/polymer/polymer.js"></script>
<script src="bower_components/webcomponentsjs/webcomponents.js"></script>
<link rel="import" href="bower_components/core-drawer-panel/core-drawer-panel.html">
body
<core-drawer-panel transition id="core_drawer_panel" touch-action>
<section id="section" drawer></section>
<section id="section1" main></section>
</core-drawer-panel>
<script>
Polymer({
});
</script>
Actually, this is exactly how it should be.
Look in your inspector and you will see that there is a core-drawer-panel element with two section's. The core-drawer-panel doesn't have any visual and is just a container that holds your sub components.
Basically you need to put something in the sections to see something in the browser :)
Add the following to your code:
<style>
core-drawer-panel /deep/ section {
border:1px solid red;
}
</style>
This will visually highlight the sections.

I have 2 different components in my Vuejs/Nuxtjs application: pages/Create.vue and pages/Design.vue. I have the stylesheet assets/css/styles.css.
Within the stylesheet styles.css I have a style: overflow:hidden;. This style sheet has been added only to my Design.vue component and not to my Create.vue component. However, I see that this style is impacting my Create.vue without even including it.
If I modify to overflow:auto; then everything works perfectly in Create.vue but Design.vue gets messed up.
I tried following things but still had no luck in making both components work perfectly:
Tried adding <style scoped> to both my Create.vue & Design.vue then also styles in Design.vue is getting messed up.
Tried adding overflow:hidden; to my Create.vue but that's not working either.
Tried adding scoped to both components then also its not working perfectly for me.
Following is the code I have from both components:
styles.css
html,
body {
overflow: hidden;
}
Create.vue:
<template>
<div>
<!-- My code with overflowing the page-->
</div>
</template>
<script>
export default {
}
</script>
<style>
/* OTHER STYLES */
</style>
Design.vue:
<template>
<div>
<!-- My code with overflowing the page-->
</div>
</template>
<script>
export default {
}
</script>
<style>
#import "~/assets/css/styles.css";
/* OTHER STYLES */
</style>
Im trying to design this webpage with multiple pages. For example, when you scroll to the about page, its a different background color than the contact page. However, so far I only got the title of each page color. My webpage is where you scroll down it lands onto another page. I tried
#name{background-color:#ffffff;}
#Portfolio{background-color:#d5f4e6;}
#about{background-color:#fefbd8;}
#ContactMe{background-color:#ffffff;}
in the css style page based on its id. Any clue on how to get the different background color on different pages
html code:
<body id="Portfolio"></body>
<body id="about"></body>
<body id="Contact Me"></body>
When you say "multiple pages" it means "separate pages in separate files!" like "aboutpage.html" or "contact.html". In this case you can work with "body" tag:
<body id="about">
but then you said "when you scroll to the about page" that means "a page with different section that you can use like this:
<p id="about"></p>
<p id="contact"></p>
or
<div id="about"></div >
<div id="contact"></div>
You should specify that the elements containing your targets are 100vh height. With your (original posted) code you can do it like that:
body > div {min-height:100vh;}
This css will catch the container-* div that you use in the code you provide. I recomand continue learning the basics. Start here https://developer.mozilla.org/he/docs/Web/HTML
Enjoy code!
If it's a same page scroller, you should add
#Portfolio,#about,#ContactMe {min-height:100vh;}
To your css.
If you can provide the exact code its much easier to help you.
simple code
$(document).ready(function(){
startFromtop=$(".start").position().top
aboutFromtop=$(".about").position().top
contactFromtop=$(".contact").position().top
endFromtop=$(".end").position().top-100
$(window).scroll(function(){
windowformtop=$(this).scrollTop();
if(windowformtop>=startFromtop && windowformtop<aboutFromtop){
$(document.body).css("background-color","white")
}
else if(windowformtop>=aboutFromtop && windowformtop<contactFromtop){
$(document.body).css("background-color","red")
}else if(windowformtop>=contactFromtop && windowformtop<endFromtop){
$(document.body).css("background-color","green")
}else if(windowformtop>=endFromtop){
$(document.body).css("background-color","blue")
}
})
})
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<title></title>
<style type="text/css">
div{height:700px;border:2px solid red;}
</style>
</head>
<body>
<div class="start">Start</div>
<div class="about">ABOUT</div>
<div class="contact">CONTACT</div>
<div class="end">END PAGE</div>
</body>
</html>
Replace <body> with the <div> tag and add the appropriate css. The pages should have the same class but unique ids. You change the background color with CSS property background-color.
HTML:
<html>
<head></head>
<body>
<div class=“page”id=“portfolio”>
</div>
<div class=“page” id=“about”>
</div>
<div class=“page” id=“contactme”>
</div>
</body>
</html>
CSS:
.page{
position:relative;
width:100%;
height: auto;
margin:auto;
}
#portfolio{
background-color:white;
}
#about{
background-color:red;
}
#contactme{
background-color:blue;
}
Hope this works for you.
Code sample
http://jsbin.com/vudulonaka/1/edit?html,output
Click the menu button on this JSBin. Notice how the text wraps. I want to:
eliminate the text wrapping and
make the menu items expand their widths to match the width of the text inside.
This might necessitate forcing the menu to expand from right to left since the button is right justified in the toolbar.
How would I do that? Please provide working JSBin code example.
Code
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Polymer Bin</title>
<base href="http://element-party.xyz">
<link rel="import" href="all-elements.html">
</head>
<body>
<x-element></x-element>
<dom-module id="x-element">
<template>
<style>
</style>
<paper-header-panel class="flex">
<paper-toolbar>
<span class="flex"></span>
<paper-menu-button>
<paper-icon-button icon="menu" class="dropdown-trigger"></paper-icon-button>
<paper-menu class="dropdown-content">
<paper-item>This is a long label for the paper menu and button to show</paper-item>
<paper-item>This is another long label for the paper menu and button</paper-item>
<paper-item>This is still yet another long label for the paper menu</paper-item>
</paper-menu>
</paper-menu-button>
</paper-toolbar>
<div class="fit">Content goes here...</div>
</paper-header-panel>
</template>
<script>
(function(){
Polymer({
is: 'x-element'
});
})();
</script>
</dom-module>
</body>
</html>
This isn't exactly perfect but it should give you an idea of the kind of css properties you should change and how to do it: http://jsbin.com/xaladokimu/1/edit?html,output
What changed is the style:
<style>
paper-menu-button{
--paper-menu-button-dropdown:{
max-width: 100%;
right:70vw;
};
}
paper-item{
--paper-item:{
white-space: nowrap;
width: 100%;
};
}
</style>
Basically, you have to add the white-space: nowrap to the items so that their text is displayed in a single line and then play around with the items' width and the dropdown menu's horizontal position and width (trying to change the dropdown's position to fixed or something else could help too)
Then again, you should set this css properties outside of the element in some custom style (unless you want your element to only work on a set position)
I have two different div's I want to make one of them invisible and after clicking the link or button I want it to be visible and the other invisible. I don't know javascript so I know only HTML and CSS. Can I do that with only using HTML&CSS and How can I do that? Thanks.
You need to use jQuery for this.
Just add this line to your head tag:
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.2.min.js">
If your HTML is like this:
<div id="div1">This is div1</div>
<div id="div2">This is div2</div>
<button id="button1">Toggle divs</button>
CSS:
#div2 {
display:none;
}
At the bottom of your page, just before the closing tag </body> add the following JavaScript:
<script>
$("#button1").on("click", function () {
$("#div1, #div2").toggle();
}
</script>
Here's a link for a similar example:

I am new to programming and have a basic question. I have a background image on my web page, but I want the content area to have a white background. I see this very commonly on the web but being new I cannot seem to figure out how to do it. I have a #wrapper div that centers my content and a css rule to show the image, just can't get the content area background to be white. Help for this newbie is appreciated!
There are several ways to achieve this. You can either set the styles of your HTML tags (div, span, p etc...) by using the style attribute as in the example:
<div style="background-color: white;"></div>
or either define your styles inside the <head></head> tag as follows:
<html>
<head>
<style>
.your_class { background-color: #ffffff; }
</style>
</head>
<body>
<div class="your_class"></div>
</body>
</html>
or either use the link tag to put your CSS code inside a file and link to it as:
<head>
<link rel="stylesheet" type="text/css" href="your_file.css">
</head>
Or sometimes you will need to set your style dynamically. Then javascript enters into the picture:
<html>
<head>
<script>
function changeBg(id, color) {
document.getElementById(id).style.bgColor = color;
}
</script>
</head>
<body onload="changeBg('myDiv', 'white');">
<div id="myDiv"></div>
</body>
</html>
You should read more on HTML and CSS to understand how it works. There are plenty of tutorials on the web.
Assuming a structure like this :
<body>
<div id="wrapper">
<section id="content"> <!-- Or div or whatever -->
Lorem ipsum dolor sit amet
</section>
</div>
</body>
You should apply a background-color to #wrapper :
body{
background-image: url("your_url");
}
#wrapper{
background-color:white;
}
Check this fiddle for a working example.
Put your content inside a div and specify background:#fff; for that div in your CSS.
