I am making matching game that images in left and right are different, and users have to find(I put one more image in left side).
My problem is that I cannot call image on where I want. What should I have to fix? Thank you.
<!DOCTYPE html>
<html>
<head>
<style>
img {
position: absolute;
}
div {
position: absolute;
width: 500px;
height: 500px;
}
#leftside {
float: left;
}
#rightside {
float: right;
left: 500px;
border-left: 1px solid black
}
</style>
<script>
var numberOfFaces(5);
var theLeftSide = document.getElementById("leftSide");
function generateFaces() {
var createElement("img");
var position = Math.floor(Math.random() * 500);
img.src = 'http://home.cse.ust.hk/~rossiter/mooc/matching_game/smile.png';
img.id = 'smileImage';
createElement.setAttribute("height", position);
createElement.setAttribute("width", position);
document.getElementById('leftSide').appendChild(img);
}
</script>
</head>
<body>
<h1>Matching Game</h1>
<p>Click on the extra smiling face on the left.</p>
<div id="leftside"></div>
<div id="rightside"></div>
</body>
</html>
You need to set something to the result of createElement('img'). For example, you can change that line to var img = createElement('img');
You never actually use theLeftSide.
createElement is actually document.createElement.
You never defined the variable createElement. Since we called it img earlier, do so now.
leftSide is not the ID of any element, but leftside is. Change it so that all usages are capitalized the same.
After that, you actually need to call generateFaces. Because the page is loaded top-to-bottom, JavaScript doesn't yet know about the div with the ID of leftSide. You have to wait until the page is finished loading to call the Javascript, and you can do that by adding window.onload = generateFaces to the end of your script.
Here's the final result:
<!DOCTYPE html>
<html>
<head>
<style>
img {
position: absolute;
}
div {
position: absolute;
width: 500px;
height: 500px;
}
#leftside {
float: left;
}
#rightside {
float: right;
left: 500px;
border-left: 1px solid black
}
</style>
<script>
function generateFaces() {
var img = document.createElement('img');
var position = Math.floor(Math.random() * 500);
img.src = 'http://home.cse.ust.hk/~rossiter/mooc/matching_game/smile.png';
img.id = 'smileImage';
img.setAttribute('height', position);
img.setAttribute('width', position);
document.getElementById('leftSide').appendChild(img);
}
window.onload = generateFaces;
</script>
</head>
<body>
<h1>Matching Game</h1>
<p>Click on the extra smiling face on the left.</p>
<div id="leftSide"></div>
<div id="rightSide"></div>

I have created a button which should shift the window's Y to "BOX - 5" div's Y middle through onclick. So in other words I want to set the "Box - 5" div in the middle of the window. I have tried many methods using window.scrollTo and using elements.innerHeight/2, but I still cannot center the element to the middle of the window/screen. Please Help.
I wish to only use Javascript, but if its not possible with it then I would accept jQuery script.
index.html:
window.onbeforeunload = function () {
this.scrollTo(0, 0);
}
var content = document.getElementById("content"),
current = 0;
for (var y=0;y<10;y++) {
var box = document.createElement("div");
box.id = "box";
box.innerHTML = "Box - " + (y+1);
content.appendChild(box);
}
document.querySelector("BUTTON").onclick = function() {
var box_5 = document.querySelectorAll("#box")[4];
/*
NEED HELP HERE
*/
}
body {
margin: 0;
}
#box {
position: relative;
height: 500px;
width: 100%;
margin: 5% auto 5% auto;
color: black;
background-color: skyblue;
border: black 1px solid;
font-size: 50px;
text-align: center;
}

Updated your snippet as below. You can use DOM element property offsetTop to check its Y position and use window.scroll to scroll the view to that element. Another sidenote, it's better to not assign the same id to multiple elements, so I change the id property to class and added identifier _{index} for the class name.
window.onbeforeunload = function () {
this.scrollTo(0, 0);
}
var content = document.getElementById("content"),
current = 0;
for (var y=0;y<10;y++) {
var box = document.createElement("div");
box.className += "box _" + (y+1);
box.innerHTML = "Box - " + (y+1);
content.appendChild(box);
}
document.querySelector("BUTTON").onclick = function() {
var box_5 = document.querySelectorAll(".box._5")[0];
if (box_5) {
// scroll the window view to the element
window.scroll({
top: box_5.offsetTop,
behavior: 'smooth',
})
}
}
body {
margin: 0;
}
.box {
height: 500px;
width: 100%;
margin: 5% auto 5% auto;
color: black;
background-color: skyblue;
border: black 1px solid;
font-size: 50px;

The box is white. Change "color" to "background-color".
I need to create simple link display like below image;
What I thought is add separate styles for all of these links. but its looks not the best way to do this.
have anyone tried something like this? can I do this with JavaScript or JQuery?
This allows you to randomly position the Text. Maybe you could edit it slightly for your needs?
<html>
<head>
<style type='text/css'>
body {
border: 1px solid #000;
height: 300px;
margin: 0;
padding: 0;
width: 300px;
}
.box {
height: 30px;
position: absolute;
width: auto;
}
#div1 { background:0;color:red; }
#div2 { background:0;color:blue; }
#div3 { background:0; color:green;}
</style>
<script type='text/javascript'>
function setDivPos() {
for (i=1; i<=3; i++) {
var x = Math.floor(Math.random()*250);
var y = Math.floor(Math.random()*250);
document.getElementById('div'+i).style.left = x + 'px';
document.getElementById('div'+i).style.top = y + 'px';
}
}
</script>
</head>
<body onload='setDivPos();'>
<div id='div1' class='box'>one word</div>
<div id='div2' class='box'>another word</div>
<div id='div3' class='box'>and so on</div>
</body>
</html>
Anyone have time to help?

Please look at the code and tell me what should i do and other thing i have a navigation which code is
<a style="display: block; height: 40px; width: 40px; background-color: red; border-radius: 20px; text-align: center; position: absolute; z-index: 2; margin-top: 130px;" href="">Home</a>

i want this in a circle as i did with border-radius and now i want it's Text in the center like Home in the middle of the circle help me also with this
For this, use:-
style="border-radius:100px; text-align:center;"
The "xmlns" attribute is invalid in HTML 4.01. (You can change your doctype.)
Also, it is more common practice to create your function.
function blaah(blaah){
blaah
}
And then add an onload event handler, either with an event listener, or add this code to your body tag,
<body onload="blaah('blaah')">
or, you could add this code in your script tags, but outside of the function.
blaah("blaah");
Call slide function.
window.onload = function() {
slideImg = document.getElementById('slideShowImage');
images = new Array();
images[0] = new Image();
images[0].src = "Images/image1.jpg";
images[1] = new Image();
images[1].src = "Images/image2.jpg";
images[2] = new Image();
images[2].src = "Images/image3.jpg";
slide();
};
I want to dynamically create 6 boxes when the page is loaded. They should be inline-block, so eventually it will look like 3 lines, with 2 boxes on each line.
I tried the code below without any JavaScript (just used some static HTML and CSS), and it seemed to work fine.
Generally, the script looks fine to me -- however, it does nothing. What am I doing wrong? Is it something about the order of the CSS and the JavaScript?
style1.css:
* {
margin:0;
padding:0;
}
header,section,nav,aside,footer{
display:block;
}
.wrapper{
position: relative;
height: 2150px;
width: 900px;
background-color: #336b98;
margin: 0 auto;
}
section#contentSection_layout3{
position: absolute;
top:193px;
height: 1957px;
width: 900px;
border-right: solid 1px #FFF;
}
HTML & JavaScript:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="includes/style1.css">
<script src="includes/JavaScript.js"></script>
<title> EX </title>
<script>
window.onload = function(){
var boxesNum = 6;
for(var i = 0; i < boxesNum; i++){
var rect = new rect();
rect.setAttribute('display', 'inline-block');
rect.setAttribute('margin-left', '200');
rect.setAttribute('margin-top', '100');
rect.setAttribute('height', '150');
rect.setAttribute('width', '150');
rect.setAttribute('background-color', '#FFF');
document.getElementById('contentSection_layout3').appendChild(rect);
}
};
</script>
</head>
<body>
<div class="wrapper">
<section id="contentSection_layout3"></section>
</div>
</body>
</html>
var rect = new rect();
Unless you have defined rect elsewhere, you want:
var rect = document.createElement('div');
Also, setAttribute is not for styles, style is for styles.
rect.style.display = 'inline-block';
rect.style.marginLeft '200px';
rect.style.marginTop = '100px';
rect.style.height = '150px';
rect.style.width = '150px';
rect.style.backgroundColor = '#FFF';
Also, don't forget your pxs.
