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 :)

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;
}
.bar:nth-of-type(1) {
position: absolute;
top: 0;
left: 0;
}
.bar:nth-of-type(2) {
position: absolute;
top: 50%;
transform: translateY(-50%);
left: 0;
}
.bar:nth-of-type(3) {

}
.menu.open .bar:nth-of-type(1) {

i tried making an easy working clock but i have no idea how to get the clock hands to rotate. i tried to use "#keyframes" to try to get it working but i dont know what to put in "before". is there a way to make it rotate using only css or will using javascript be easier. the link below shows my work but you can also look below and see my code.

Pure HTML/CSS second hand:
#clock_container {
position: absolute;
top: 20px;
left: 20px;
width: 150px;
height: 150px;
border-radius: 50%;
border: 2px solid black;
}
#seconds {
height: 50%;
width: 0px;
box-sizing: border-box;
border: 1px solid black;
top: 0%;
left: 50%;
position: absolute;
transform-origin: bottom;
/* of-course, would be 60s */
animation: secondsMotion 10s infinite linear;
}
#keyframes secondsMotion {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
<div id="clock_container">
<div id="seconds"></div>
</div>
If you wanted to start with the correct time - with a little JS early on:
var sec = new Date().getSeconds();
var sec_start = (sec/60) * 360 + 'deg';
var sec_end = (sec/60) * 360 + 360 + 'deg';
document.documentElement.style.setProperty("--sec-rot-start", sec_start);
document.documentElement.style.setProperty("--sec-rot-end", sec_end);
and then, in the keyframes:
#keyframes secondsMotion {
0% {
transform: rotate(var(--sec-rot-start));
}
100% {
transform: rotate(var(--sec-rot-end));
}
}
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 #.
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 }
}

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.
This question already has answers here:
How can I vertically center a div element for all browsers using CSS?
(48 answers)
Closed 6 years ago.
I am trying to centre a DIV which contains a form. I have managed to grey out the back ground and would like to centre the form within the window. Below is what I have done so far, but I do not know how to progress it further to get the result that I need.
I am able to 'auto margin' horizontally, but I am not able to do this vertically (please see image). If you stretch the browser window further vertically, the form stretches to occupy all of the vertically space.
#idOfForm{
margin: auto;
z-index: 10000;
position: absolute;
background-color: white;
top: 0;
bottom: 0;
left: 0;
right: 0;
padding: 10px;
width: 500px;
min-height: 250px;
border: 1px solid #ccc;
border-radius: 10px;
box-shadow: 3px 3px 3px #b8b8b8;
font-family: sans-serif;
color: #484848;
}
This is how you can center elements easily:
Suppose you have the following:
<div class="aaa">
fsdfsd
</div>
Use the following css:
.aaa {
transform: translate3d(-50%, -50%, 0);
position: absolute;
top: 50%;
left: 50%;
}
Here is jsfiddle: https://jsfiddle.net/ffnvjz4q/
This is the code you need:
#idOfForm{
transform: translate3d(-50%, -50%, 0);
z-index: 10000;
position: absolute;
background-color: white;
top: 50%;
bottom: 0;
left: 50%;
right: 0;
padding: 10px;
width: 500px;
min-height: 250px;
border: 1px solid #ccc;
border-radius: 10px;
box-shadow: 3px 3px 3px #b8b8b8;
font-family: sans-serif;
color: #484848;
}
What browsers does your 'app' must support ? The easiest way to achieve this is using CSS flexbox but it is not fully support yet

.parent {
display: flex;
height: 300px; /* Or whatever */
}
.child {
width: 100px; /* Or whatever */
height: 100px; /* Or whatever */
margin: auto; /* Magic! */
}
<div class="modal">
<div class="modal-body">
<!-----put your form code here --->
</div>
</div>
.modal {
position: fixed;
top: 0;
bottom: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0,0,0,0.4);
z-index: 2;
}
.modal-body {
position: relative;
max-width: 500px;
width: 100%;
margin: 50px auto 20px;
background-color: #fff;
min-height: 50px;
}
You could try
.element {
position: relative;
top: 50%;
transform: translateY(-50%);
}
