The problem is you are loading your js script before rendering elements on the page.
You can use defer attribute for the script tag to launch script after page rendering.
<script src="js/myscript.js" defer>
getElementsByTagName() is returning a HTMLCollection, so here is a working code:
console.log('test1');
let elemens = document.getElementsByTagName('p');
for (let i=0; i < elemens.length; i++) {
elemens[i].style.color = 'red';
}
console.log(elemens);
And by the way, is it a typo with elemens variable up above?

Wrap Javascript code in DOMContentLoaded event
Like
document.addEventListener("DOMContentLoaded", function(event) {
//do work
});
More information
https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/onload
document.addEventListener("DOMContentLoaded", function(event) {
console.log('test1')
let elemens = document.getElementsByTagName('p');
for (let i = 0; i < elemens.length; i++) {
elemens[i].style.color = 'red';
}
});

You are loading the script tag in the Head without any delay. So when the page loads, it loads JS first then the body of the Page. I will suggest calling it after the body so that the whole page loads first and after that, the JS loads so that it can have access to the DOM otherwise it will not find any object. That is why it is not working. Load it like this:
</body>
<script src="name.js"></script>
</html>
After the body tag and it should work just fine.

This is mostly because your javaScript is loading before the completely loading of DOM.
there is two Way you can Solve this
1st By wrapping you js code with
window.onload = function() {
// Your code
}
2nd By placing your Script tag after body.
</body>
<script src="name.js"></script>
</html>

Parallax effect - force text block to behave like background-attachment: fixed

I'm attempting to create a simple parallax effect where each 100vh section scrolls up to reveal the next section (new background color, background image, and text block) while keeping the text block fixed relative to its parent container.
I've put together a static example of what I'm trying to achieve using screenshots of each section: static example. Of course I'd like the content to be dynamic rather than flat images.
Here's a simple version of my code thus far:
body {
margin: 0;
padding: 0;
}
h2 {
font-size: 48px;
}
p {
font-size: 18px;
}
section {
min-height: 100vh;
width: 100%;
text-align: center;
position: relative;
background-attachment: fixed !important;
background-size: cover !important;
background-repeat: no-repeat !important;
}
section.first {
background: url(https://picsum.photos/1920/500/?image=1057);
}
section.first .content {
background-color: rgba(74, 180, 220, .85);
}
section.second {
background: url(https://picsum.photos/1920/500/?image=1067);
}
section.second .content {
background-color: rgba(103, 198, 180, .85)
}
section.third {
background: url(https://picsum.photos/1920/500/?image=1033);
}
section.third .content {
background-color: rgba(5, 123, 188, .85);
}
section.fourth {
background: url(https://picsum.photos/1920/500?image=1063);
}
section.fourth .content {
background-color: rgba(187, 216, 100, .85)
}
.content {
position: relative;
height: 100vh;
width: 100%;
padding: 50px 0;
}

The parallax effect is achieved using CSS background-attachment: fixed and works just fine; the trouble is with the text blocks. I'd like to keep them "pinned" in place and centered within their section. If they are set to position: fixed they of course overlap each other and all show up in the first section. If they are set to any other position attribute, they will simply scroll like any other element.
Now, I realize that setting an element's position to fixed means it can no longer be relative to its parent element; it escapes the flow so to speak, but I'm trying to determine if there's a way to achieve the effect with some advanced CSS or even a JS alternative.
I've tried numerous HTML/CSS combinations (wrappers within wrappers, etc.) and I've also attempted various javascript solutions such as rellax, jarallax, and ScrollMagic, but everything I've come across is far too robust for my needs. I've searched around for the better part of the day hoping to find an example of what I'm attempting, but no luck.

In a previous question I did a similar effect with image and using some JS so am going to use the same technique to reproduce this using content as I don't think there is a pure CSS solution. So the idea is to simulate the fixed position by using absolute position and adjusting the top property dynamically on scroll.
Here is an example where I also adjusted some of the CSS to make it easier. I will also rely on CSS variables to make the JS code very light so we can manage everything with CSS.
window.onscroll = function() {
var scroll = window.scrollY || window.scrollTop || document.getElementsByTagName("html")[0].scrollTop;
document.documentElement.style.setProperty('--scroll-var', scroll + "px");
}
:root {
--scroll-var: 0px
}
body {
margin: 0;
padding: 0;
}
h2 {
font-size: 48px;
}
p {
font-size: 18px;
}
section {
min-height: 100vh;
width: 100%;
text-align: center;
overflow: hidden;
background-attachment: fixed !important;
background-size: cover !important;
background-repeat: no-repeat !important;
position: relative; /*Mandatory for the overflow effect*/
height: 100vh;

I have put up a little snippet, that works. But you need to figure out the exact math behind positioning yourself. And of course take care of the details
$( document ).ready(function() {
$(document).scroll(function() {
// get the position of my first slide, so I know where did I move
var rect = $(".first")[0].getBoundingClientRect();
// get height of viewport
var screenHeight = $( window ).height();
// setting offset for every .copy element on page, so they share
// the same offset from top (are on top of each other)
// Now you just need to figure out exact math here
$(".copy").offset({ top: screenHeight*1.5-rect.bottom});
});
});
body {
margin: 0;
padding: 0;
}
h2 {
font-size: 48px;
}
p {
font-size: 18px;
}
section {
min-height: 100vh;
width: 100%;
text-align: center;
position: relative;
background-attachment: fixed !important;
background-size: cover !important;
background-repeat: no-repeat !important;
/* added overflow hidden, so that my boxes don't flow out of the slide */
overflow: hidden;

How to set a bottom border for every row in a textarea?

I am trying to figure out how to add a border-bottom line for every row within a <textarea>, however I am only able to get the very bottom row's border-bottom to do this.
Is there a way to accomplish this?
.input-borderless {
width: 80%;
border-top: 0px;
border-bottom: 1px solid green;
border-right: 0px;
border-left: 0px;
background-color: rgb(241,250,247);
text-decoration: none;
outline: none;
display: block;
padding: 10px 0;
margin: 20px 0;
font-size: 1.6em;
}
<textarea rows="3" class="input-borderless" placeholder="Describe the project"></textarea>

You can use gradient as the background image to get an effect that looks like underline:
JSFiddle
textarea
{
line-height: 4ch;
background-image: linear-gradient(transparent, transparent calc(4ch - 1px), #E7EFF8 0px);
background-size: 100% 4ch;
}

The idea is to use layers, make the textarea as top layer, the multiple lines as bottom layer.
I'm using a pseudo element for the bottom layer, since :before and :after does not work on a textarea, so I set it on the container div element.
For the bottom lines, I simply use underscores _, with \A for a line break, you can have as many lines as needed with a number of \A. The height of each line will get updated automatically according to the font size.
Jsfiddle Example
.container {
width: 200px;
border: 1px solid green;
position: relative;
overflow: hidden;
}
.container:before, .container textarea {
font-family: sans-serif;
font-size: 20px;
}
.container textarea {
width: 100%;
box-sizing: border-box;
background-color: transparent;
border: 0;
outline: none;
display: block;
line-height: 1.2;
}
.container:before {
position: absolute;
content: "____________________\A____________________";
z-index: -1;
left: 0;
top: 0;
width: 100%;
color: silver;
line-height: 1.4;
}
<div class="container">
<textarea rows="3" placeholder="Hello"></textarea>
</div>

Last week I found out about contenteditable. This morning, this thought suddenly came to me: Using an SVG background in a textarea doesn't scroll without the help of Javascript, but I bet it would scroll just fine with a DIV. Voila!
#wrapper {
display: inline-block;
width: 10em;
height: 4em;
border: 1px solid gray;

}

vertical-align: bottom;
background-size: 1px 1em;
background-repeat: repeat;

/*for placeholder, see https://codepen.io/flesler/pen/AEIFc */
}
<textarea id="TA"></textarea>
<div id="wrapper"><div contenteditable="true" id="paper">I am trying to figure out how to add a border-bottom line for every row within a, however I am only able to get the very bottom row's border-bottom to do this.</div></div>

Everything, minus the internal padding.
$(document).ready(function() {
$('textarea.styleme').scroll(function(event) {
$(this).css({'background-position': '0 -' + $(this).scrollTop() + 'px'})
})
})

CSS content and menu positioning

http://postimg.org/image/sadzaa0up/
I'm trying to get the JS navigation buttons to fall inline with a full width background/box so the buttons aren't just floating. When I try to set this in the CSS I find the buttons aren't in line with this background/box/container. They sit slightly above it. I've tried altering margins etc but had no luck.
I'm not sure if the issue is related but I'm finding I can't position the nav bar directly beneath the logo container/header. It's being pushed so it's a 150px or so below the logo with a big gap between.
Then finally, the main body content area won't stretch to the width on the left side. I've sorted the right side using margins, yet the left side won't get rid of the gap.
Any help on this is greatly appreciated.

Resizing divs depending on information inside

I have a container where I want to hold information (which would be updated regularly). But sometimes, I might want this information to be long or short, and for this I cant have a fixed height on my container, so depending on the amount of text/information it should resize. Here's my script.
HTML:
<html>
<head>
<title>LoL Champs</title>
<link rel="stylesheet" type="text/css" href="css/css.css">
<link href='http://fonts.googleapis.com/css?family=Sansita+One' rel='stylesheet' type='text/css'>
<link href='http://fonts.googleapis.com/css?family=Belleza' rel='stylesheet' type='text/css'>
</head>
<body>
<!-- NAVIGATION -->
<div id="nav-bar">
<div id="nav-bar-title">LoL Champs</div>
<ul>
<li>Champs</li>
<li>Info</li>
<li>Guides</li>
<li>Model Viewer</li>
<li>Lists</li>
</ul>
</div>
<!-- END NAVIGATION -->
<div id="main-body">
<div id="nav-body-divider"></div>
<p id="home-body-title">News</p>
<!-- News Container -->
<div id="news-container">
</div>
</div>
</body>
</html>
And CSS:
/** MAIN PAGE CONFIG CSS **/
html, body {
width: 100%;
height: 100%;
margin: 0 auto;
max-width: 1920px;
max-height: 1050px;
font-size: 100%;
}
html {
background: url(../images/JinxBG.jpg) 0 0 fixed;
-webkit-background-size: cover;

}
p {

}
a:link {color: inherit;}
a:visited {color: inherit;}

a {text-decoration: none;}
/** MAIN CSS **/
/**NAVIGATION**/
#nav-bar {

background-color: #A62D2D;
position: fixed;
box-shadow: 0px 2px 9px black;
font-size: 100%;
max-height: 10%;
max-width: 100%;
}
#nav-bar-title {

}
#nav-bar li {

display: inline;
height: 100%;
-webkit-transition: color 0.5s ease;
}
#nav-bar li:hover {
color: #C7C7C7;
-webkit-transition: color 0.5s ease;
}
/** END NAVIGATION **/
/** MAIN TEXT BODY **/
#nav-body-divider {

}
#main-body {

}
/** MAIN BODY NEWS **/
#home-body-title {
font-size: 2.4em;
font-family: Belleza;
color: #C98A5D;
position: relative;
left: 3%;
top: 0%;
}
#news-container {
width: 45%;
height: 40%;
background: #CF4040;
-webkit-border-radius: 7px;
-moz-border-radius: 7px;
border-radius: 7px;
position: relative;
left: 3%;
}
I want to resize news-container so that it adapts to the amount of stuff in it, but resize it only on height. The width should stay the same. Also, if the div will be bigger, how can I move the objects that will be below that div to accommodate further down on the page and make space for the big container?
Cheers, Nick

You should never set a height on anything. Always let the content grow naturally. http://jsfiddle.net/LQkj3/
<div id="news-container">
<p>
This is the news section! height will automatically grow depending on the amount of data! you should NEVER control height with pixels or percentage! always let the content grow it automatically.
</p>
</div>
<style>
#news-container { width: 45%; background: #CF4040; -webkit-border-radius: 7px; -moz-border-radius: 7px; border-radius: 7px; position: relative; left: 3%; padding: .5em 1em; }
</style>
...Unless of course you need a scrollable container (like #griegs suggested). ;)
Then you could put a max-width: 10em; or something to that effect.

<div style="width:200px; border: 1px solid black; max-height: 400px; overflow: scroll">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam et iaculis dui, id dapibus nibh. Phasellus sollicitudin urna non elementum aliquam. Vivamus nec aliquet quam. Mauris eget sollicitudin tellus, at dictum tellus. Donec sed porttitor quam, in suscipit nisl. Praesent vestibulum auctor turpis quis vulputate. Quisque eget erat vel tellus pretium bibendum. Mauris feugiat urna nec pharetra bibendum. Integer consectetur nisl cursus aliquam rhoncus. Mauris vulputate pulvinar commodo. Mauris placerat enim erat, a dignissim metus laoreet quis. Aenean nec ipsum neque. Proin adipiscing tellus ut nisi rutrum tempus. Aliquam erat volutpat. In dignissim consectetur tellus sit amet sagittis. Nam ac quam id nunc adipiscing commodo.
</div>
Remove the overflow and the max-height if these are not important to you. I put them in to demonstrate that pure css should be all you need.
As the div grows, the elements below it will be pushed down so long as they are not positioned absolute or floated etc.
