CSS letter-spacing together with line-through

Is there any css/js solution how to center line through the text while using letter-spacing? While single line text it is possible to accomplish centered line-through thanks to pseudo element ::before or ::after, but that's not possible on block elements like <p> or <div>.
h2, p {
letter-spacing: 1em;
text-decoration: line-through;
text-align: center;
}
p {
letter-spacing: .5em;
}
<h2>Random text</h2>
<p>Lorem ipsum dolor sit amet, at nemore aperiri cum. Regione honestatis ei quo, ne eos aliquid mediocrem, ne viris quodsi epicuri vel. Ex dolorem atomorum dissentiunt nam, iudico minimum cotidieque eum et, has novum mnesarchum id. Libris blandit liberavisse mei in. Ius viris posidonium ei, ut quas viris albucius eum, mei eu indoctum reformidans. Et usu sumo invidunt, cu vix veri dolore propriae.</p>

Here is an idea where you can rely on background and box-decoration-break to create the line-through and you can easily adjust its size and position. You will basically remove one letter spacing from the total width.
It's important to note that the background need to be applied to an inline element:
p {
letter-spacing: .5em;
text-align:center;
}
p span {
background:
linear-gradient(#000,#000) /* Coloration */
0 calc(50% + 0.2ex) /* position */
/
calc(100% - .5em) 1px /* width height */
no-repeat;
-webkit-box-decoration-break: clone;
box-decoration-break: clone;
}
<p><span>Lorem ipsum dolor sit amet, at nemore aperiri cum. Regione honestatis ei quo, ne eos aliquid mediocrem, ne viris quodsi epicuri vel.

How to always show scrollbar of inner div when outer div has a smaller width

I have ended up in a scenario where the outer div has a definite height and width whereas the inner div has a definite height but an indefinite width. Like so:
html:
<div id="parent">
<div id="child">
</div>
</div
and css:
#parent{
width: 200px;
height: 200px;
overflow-x:scroll;
overflow-y:hidden
}
#child{
width: 400px;
height: 200px;
overflow-x:hidden;
overflow-y:scroll;
}
But as expected, I can see the scrollbar of inner div only when it has been scrolled to the extreme right.
I want to always show both scrollbars.
Please help me find a CSS solution or a plain js (non-jquery) solution.
https://jsfiddle.net/n2tfe2wr/

Try with this:
document.getElementById('child-size').style.width = document.getElementById('child-wrapper').scrollWidth+ 'px';
document.getElementById('parent').addEventListener('scroll', function () {
document.getElementById('child-wrapper').style.marginLeft = document.getElementById('parent').scrollLeft + 'px';
document.getElementById('child-wrapper').scrollLeft = document.getElementById('parent').scrollLeft;
})
#parent {
width: 200px;
height: 400px;
overflow-x: scroll;
overflow-y: hidden;
position: relative;
}
#child-wrapper {
width: 200px;
height: 200px;
overflow-x: hidden;
overflow-y: scroll;
background-color: blue;
}
#child {
width: 400px;
color: white;
}
#child-size {
height: 1px;
opacity: 0;
}

Polymer - Multiple accordions using computed bindings

I am trying to replicate the multiple iron-collapses in my app like the example but running into problems:
https://elements.polymer-project.org/elements/iron-collapse?view=demo:demo/index.html&active=iron-collapse
The error I get is:
[my-app::_createEventHandler]: listener method `_expandClicked('#collapse1')` not defined
The Markup
<a>
<span>Parent Link 1</span>
<paper-icon-button icon="expand-more" role="button" on-click="_expandClicked('#collapse1')"></paper-icon-button>
</a>
<iron-collapse id="collapse1">
<a class="link" href="/view2">Sport F</a>
<a class="link" href="/view3">Child C</a>
</iron-collapse>
The Function
_expandClicked: function(selector) {
document.querySelector(selector).toggle();
// Don't propagate to the anchor link.
event.preventDefault();
event.stopImmediatePropagation();
}
Any ideas?
Thanks!

When setting up an annotated event listener, the value must be the method name only. You could pass a function argument as a data attribute that your event listener could read.
// template
<paper-button on-tap="_toggleCollapse" data-selector="#collapse1">
// script
_toggleCollapse: function(e) {
const selector = e.target.dataset.selector;
this.$$(selector).toggle();
}
HTMLImports.whenReady(() => {
"use strict";
Polymer({
is: 'x-foo',
_toggleCollapse: function(e) {
// Assume e.target is the paper-button or an immediate child
const selector = e.target.dataset.selector || e.target.parentElement.dataset.selector;
if (selector) {
this.$$(selector).toggle();
}
}
});
});

Scrolling to see more of fixed div if overflows?

I have a popup modal window that is positioned fixed and with a set width and height. It is also centered on the window:
It all works fine, except if the window height is reduced far enough, part of the div is cut off, with the user unable to see all of its content:
Is there a way to add scrolling to the parent container (which is also fixed) to see the rest of the modal/div?
Here is the JSFiddle
*{ margin:0; }
#popup-background
{
position:fixed;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.5);

height: 350px;

right: 0;
margin: auto;
}
<div id="popup-background">

Update the css like this
*{ margin:0; }
#popup-background
{
position:fixed;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.5);
}
#popup-modal
{
padding: 20px;
width:500px;
max-height: 350px;
height :80%;
background: #EFEFEF;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
overflow-y: auto
}

After reading #mokiSRB comment, I changed my modal from being fixed to relative. Then I found How do I vertically center align a position:relative element, which suggested wrapping the relative div twice with:
.wrappert {
height: 100%;
width: 100%;
display: table;
}
.wrapper {
height: 100%;
vertical-align: middle;
display: table-cell;
text-align: center;
}
After some more minor tweaks I ended up with: http://jsfiddle.net/senju/ynjn2u7L/
*{ margin:0; }
#popup-background
{
position:fixed;
width: 100%;
height: 100%;

If you dont want the modal be scrollable, but the whole page instead do this:
CSS:
.background{
position: fixed;
width: 100%;
height: 100%;
background: rgba(0,0,0,0.5);
top: 0px;
left: 0px;
}
.modal_container{
position: fixed;
width: 100%;
height: 100%;
overflow: auto;
}
.modal_wrapper{
text-align: center;
position: absolute;
width: 100%;
height: 100%;
left: 0;
top: 0;
}
.modal_content{
background: white;
position: relative;
display: inline-block;
padding: 20px;
margin-top: 10px;
vertical-align: middle;
z-index: 999;
max-width: 350px;
}
HTML:
<div class="background"></div>
<div class="modal_container">
<div class="modal_wrapper">
<div class="modal_content">
MY CONTENT
</div>
</div>
</div>
But be careful, when opening the modal you should set overflow:hidden to the html tag, because if you dont you can get 2 scrollbars which looks ugly.

Easy way to switch between content with jquery

I just made a script that shows/hides content with Jquery when you click on tabs above the content (it also changes the color of the tab that was clicked). Everything works fine (Result: https://jsfiddle.net/e572s3oq/embedded/result/) but i think there is an other way to switch between the content that makes it easier to add more tabs. I would be really glad if someone could help me. And i hope you understand my intention. (Please excuse my english and ask me if you have any remaining questions)
Here is my Code (I think only the jQuery code is relevant):
$(document).ready(function() {
$(".tab:first-child").click(function() {
$(".content p:nth-child(2)").css('display', 'none');
$(".tab:nth-child(2)").css('background-color', '#F5F7F7');
$(".tab:first-child").css('background-color', 'white');
$(".content p:first-child").css('display', 'block');
});
$(".tab:nth-child(2)").click(function() {
$(".content p:first-child").css('display', 'none');
$(".tab:first-child").css('background-color', '#F5F7F7');
$(".tab:nth-child(2)").css('background-color', 'white');
$(".content p:nth-child(2)").css('display', 'block');
});
});
body,
html {
padding: 0;
margin: 0;
background-color: #ecf0f1;
}
#wrapper {
width: 260px;
margin: auto;
margin-top: 100px;
}
.tab {
width: 130px;
height: 30px;
font-family: 'Lato', sans-serif;
font-size: 14px;
line-height: 30px;
text-align: center;
color: #7f8c8d;
display: block;
float: left;
}
.tab:hover {
cursor: pointer;
}
.tab:first-child {
background-color: white;
}
.tab:nth-child(2) {
background-color: #F5F7F7;
}
.content {
width: 260px;
height: 300px;
background-color: white;
overflow: scroll;
}
.content p {
color: #7f8c8d;
font-size: 12px;
font-family: 'Lato', sans-serif;
margin-top: 8px;
margin-left: 8px;
margin-right: 8px;
margin-bottom: 5px;
}
.content p:first-child {
display: block;
}
.content p:nth-child(2) {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id=wrapper>
<div class="tab">
PAGE 1
</div>
<div class="tab">
PAGE 2
</div>
<div class="content">
<p>Content1</p>
<p>Content2</p>
</div>
</div>

This should do:
$('.tab').click(function() {
$('.content p').hide();
$('.tab').css('background-color', '#F5F7F7');
$(this).css('background-color', 'white');
$('.content p').eq($(this).index()).css('display', 'block');
});
What basically is happening is:
We first, by default, hide all the p elements within the .content div.
We also set background-color to #F5F7F7 for all the .tab elements.
Then, you can target the current .tab element by the use of $(this) and set its background-color to white.
Finally, we can target a particular p element within .content div by using the current .index() of the current .tab element and then we feed this .index() to another method of jQuery called .eq() which then gets us the desired p element.
Snippet:
$('.tab').click(function() {
$('.content p').hide();
$('.tab').css('background-color', '#F5F7F7');
$(this).css('background-color', 'white');
$('.content p').eq($(this).index()).css('display', 'block');
