When I press the X, I able to open the searchbox with animation. I also able to close the searchbox when I click on the X inside the searchbox but without animation. I tried to change the animation-name in Javascript, but it has no effect. Anyone can help me with the code, if possible I try not to use jQuery. Thanks in advance

Try to use two CSS #keyframes Rule. One for opening and other for closing the element. Also remove the width, display and animation-name from #searchbox style list.
Do this:
function openSearchBox() {
var searchbox = document.getElementById( 'searchbox' );
searchbox.style.animationName = 'open';
searchbox.style.width = '100%'
}
function closeSearchBox() {
var searchbox = document.getElementById( 'searchbox' );
searchbox.style.animationName = 'close';
searchbox.style.width = '0'
}
#keyframes open {
0% { width: 0 }
100% { width: 100% }
}
#keyframes close {
0% { width: 100% }
100% { width: 0 }
}

try to use transition:width 1s; in #searchbox 's css
#searchbox {
display: none;
position: absolute;
background-color: pink;
width: 100%;
height: 35px;
border-radius: 25px;
right: 0;
top: 50%;
transform: translate(0, -50%);
overflow: hidden;
/* animation-duration: 1s;*/
float: right;
/*animation-name: open;*/
transition:width 1s;
}
You are animating a element that has a display: none property. This property can't be animated in css. A solution can be to remove the display none property and find another solution like: overflow: hidden and width: 0.
I also recommend doing style changes in css only and not in JavaScript, this will speed up your website. By just adding a simple class you have more controll in your css and your JavaScript files.

Thank you in advance for your help :)
This snippet will get you closer to your second image. I changed up the structure a bit and just used a couple spans and positioned them absolute. You can tinker with the animation to your hearts content.
$(".menu").click(function () {
$(this).toggleClass("open");
});
body {
background-color: black;
}
.btn5 {
position: absolute;
width: 150px;
display:flex;
align-items: center;
height: 150px;
top: 0px;
left: 0px;
transition-duration: 0.5s;
border: 5px solid red;
}
.icon {
width:150px;
height:150px;
position: relative;
}
.btn5 .bar {
transition-duration: 0.5s;
position: relative;
height: 8px;
width: 100%;
height: 20px;
display: block;
background-color: white;
}

I want to create a look that allows when a user press the "Scroll" button, the page will scroll with sliding effect. But it does not work on my page. I tried add with tag to my html file but it does not work too.
I found a script for that but it did not work.
Where is my mistake?

Your problem was here
$('a[href*=#]').on('click', function(e) { ...
To target the anchor elements that have a href attribute which begin with the # character you would use ^ (instead of *), which means starts with, and you would also add some parentheses around the search character like this
$('a[href^="#"]').on('click', function(e) { ...
Check below:
Note: I purposefully gave the body a height of 1000px so we can test and run here.
$(function() {
$('a[href*="#"]').on('click', function(e) {
e.preventDefault();
$('html, body').animate({ scrollTop: $($(this).attr('href')).offset().top}, 500, 'linear');
});
});
body {

You can also use the * as a wild card instead of ^, which will then match anchor elements that have a # character anywhere in their href attribute, and not just begin with #.
We are displaying text & two radio buttons in page....
Once we click on Radio buttons, we are changing background color of page according to radio button....
Requirement :

You need to use JS/jQuery for this because > + ~ this are siblings selector so it only select item that are next to it
+ is the immediate subsequent sibling selector
~ is the any subsequent sibling selector

$(this).parent().siblings('div.text').css('color', '#FFB300');
}

You need jQuery/js for that - This is a Solution with jQuery:
$(document).ready(function() {
var text = $('.text')
$('input:radio').change(function() {
if ($(this).is(':checked')) {
var color = $(this).val();
text.css('color', color);
}
});
});

Alos please be aware that amber is no usable color, so I changed that for exemplary usage to green
Updated answer is here
function myColour(clr)
{
alert(clr);
if(clr == 'orange')
document.getElementsByClassName("text")[0].style.color = '#F4511E'
else if(clr == 'amber')
document.getElementsByClassName("text")[0].style.color = '#FFB300'
else
document.getElementsByClassName("text")[0].style.color = 'black'
}

I've been following the design of the Material developed by Google and they have a new bottom navigation bar with a shape I would love to know if it's possible to archive on the Web.
Thanks in advance for sharing your knowledge.
Custom shape bottom navigation
You will need to use some tricks to make this happen, however you should really look to post your attempt to see how your attempt can be amended.
Here I have used a :before and :after pseudo element to create the curves on the bottom element, and a border colour of red to create the shape.
You can just use the :hover elements as standard, I just used it for effect :)
html {
height: 100%;
margin: 0;
padding: 0;
background: red;
position: relative;
}
.bottom {
position: absolute;
bottom: 0;
left: 0;
width: 100%;
height: 120px;
transition: all 0.4s;
background: white;
}
.circle {
position: absolute;
top: -50px;
transition: all 0.4s;
left: 50%;
transform: translate(-50%, -50%);
height: 50px;
width: 50px;
background: transparent;
border: 5px solid red;
border-radius: 50%;
}
body:hover .bottom:before,
body:hover .bottom:after {
bottom: 100%;
}
.bottom:before,
.bottom:after {
content: "";
transition: all 0.4s;
position: absolute;
bottom: calc(100% - 20px);
width: calc(50% - 30px);
height: 20px;
background: white;
}
.bottom:before {
border-radius: 0 20px 0 0;
left: 0;
}
.bottom:after {
border-radius: 20px 0 0 0;
right: 0;
}
body:hover .circle {
top: 0;
background: white;
}
body:hover .bottom {
height: 100px;
}
body:hover .circle:hover {
background: gold;
cursor: pointer;
}
<div class="bottom">
<div class="circle"></div>

I'm not sure how to center my text vertically. Basically, when I click a button the page will gray out with a loading text. I managed to center it horizontally but can't do it in vertical.
CSS
.LockOff {
display: none;
visibility: hidden;
}
.LockOn {
display: block;
visibility: visible;
position: absolute;
z-index: 999;
bottom: 0px;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
background-color: #ccc;
text-align: center;
padding-top: 20%;
filter: alpha(opacity=75);
opacity: 0.75;
}
.lockMsg {
color:black;
font-weight: bold;
}
HTML
<script type="text/javascript">
function lockScreen() {
var lock = document.getElementById('divLock');
if (lock)
lock.className = 'LockOn';
lock.innerHTML = "<h1 class=\"lockMsg\">YOUR REQUEST IS BEING PROCESSED. PLEASE WAIT.</h1>";
}
</script>
<div id="divLock" class="LockOff"></div>
You need to change your CSS a little bit to achieve that as:
.LockOn {
display: block;
visibility: visible;
position: absolute;
z-index: 999;
bottom: 0px;
top: 0px;
left: 0px;
width: 100%;
background-color: #ccc;
text-align: center;
padding: 0;
filter: alpha(opacity=75);
opacity: 0.75;
}
.lockMsg {
color: black;
font-weight: bold;
position: absolute;
left: 0;
right: 0;
top: 50%;
-webkit-transform: translateY(-50%);
-moz-transform: translateY(-50%);
transform: translateY(-50%);
text-align: center;
}
Just add these three lines to your css for .LockOn
.LockOn{
display:flex;
align-items:center;
justify-content:center;
}
Here's a working snippet. I changed your script a liitle bit to show it working.
(function lockScreen() {
var lock = document.getElementById('divLock');
if (lock){
lock.className = 'LockOn';
}
lock.innerHTML = "<h1 class='lockMsg'>YOUR REQUEST IS BEING PROCESSED. PLEASE WAIT.</h1>";
})();
.LockOff {
display: none;
visibility: hidden;
}
.LockOn {
display: block;
visibility: visible;
position: absolute;
z-index: 999;
bottom: 0px;
top:0px;
left: 0px;
width: 100%;
height: 100%;
background-color: #ccc;
text-align: center;
filter: alpha(opacity=75);
opacity: 0.75;
display:flex;
align-items:center;
justify-content:center;
}
.lockMsg {
color:black;
font-weight: bold;
}
<div id="divLock" class="LockOff"></div>
