I created following simple website. I have Starfield and galaxy pictures. Starfield is animated by JS code. Stars are moving. But when I place Galaxy over starfield with CSS code stars stop moving.
Below I placed JS code and HTML code without placing galaxy over starfield. How can I place one over another with stars moving?

setInterval(move, 100, image);
}
var motion = true;
function move() {
if(motion) {
let image = document.getElementById("star");
imageLeft = imageLeft + 1;
image.style.left = imageLeft + "px";
if (imageLeft == 0) {

This finally would be working. I have used a file from my github repo to make the example working. But you can always that path.
// You can replace your whole JS with this code
fetch("https://raw.githubusercontent.com/ArunBohra33/json-data/main/clickable-pic") //file json objects
.then(function (response) {
return response.json();
})
.then(function (data) {
appendData(data);
})
.catch(function (err) {
console.log("error: " + err);
});
function appendData(data) {
var mainContainer = document.getElementById("myData");
for (var i = 0; i < data.results.length; i++) {
var img = document.createElement("img");
// New code
// Add a id to the image
img.setAttribute("id", "popup-image" + (i + 1));
img.src = data.results[i].picture.large;
img.classList.add("popup-img");
img.setAttribute("data-data", JSON.stringify(data.results[i]));
mainContainer.appendChild(img);
// Old code
var div = document.createElement("div");
div.innerHTML = "first: " + data.results[i].name.first + " First Name :" + data.results[i].name.last;
mainContainer.appendChild(div);
// if (i == data.results.length - 1) clickOnImg();
}
for (let i = 0; i < data.results.length; i++) {
document.querySelector(`#popup-image${i + 1}`).addEventListener("click", function () {
var firstName = data.results[i].name.first;
var lastName = data.results[i].name.last;
showData(firstName, lastName, i + 1);
});
}
}
// This function shows the modal with data in it
function showData(firstName, lastName, index) {
var popupBox = document.createElement("div");
popupBox.style.display = "flex";
popupBox.setAttribute("id", "popupBoxOverlay_{i}");
popupBox.classList.add("popupBox");
popupBox.innerHTML = `<div class="modal">
<span class="cross-btn-${index - 1}">×</span>
<div class="fname">
<label>FirstName: </label>
<span class="firstName${index - 1}">${firstName}</span>
</div>
<div class="lname">
<label>LastName: </label>
<span id="lastName${index - 1}">${lastName}</span>
</div>
</div>`;
document.body.prepend(popupBox);
var crossBtn = document.querySelector(".cross-btn-" + (index - 1));
crossBtn.addEventListener("click", function () {
popupBox.remove();
});
}

</html>
and here is the csv file -
name,age
pragyan,23
rashmi,26
tumon,40
debajit,50
dhiraj,19
I want to give condition that the color should be red if the age is above 30. I have tried the color part in a separate code and it was working but when I tried it in here, it is not working. Removing the color part, the height is working just fine.
How can I add two style properties? Please help.
1) Instead of color use background-color.
2) Make the age a number by setting d.age = +d.age.
Currently its a string so d.age > 30 will not work as expected.
.style("background-color", function(d) {
d.age = +d.age;
if (d.age > 30) {
return "red";
} else {
return "blue";
}
});

I'm making an HTML5 game using Tululoo.
I want to play the game in fullscreen. I used CSS to display the game in fullscreen. There is an image beneath the Tululoo game (div) where I want to display the score. I gave the scores an X and Y position, to be on top of the image.
When I activate fullscreen, the tululoogamewill be centered in the middle of the page. Now I want the score image to be placed beneath the game, and the scores to be placed at the exact same point on the image, as I did when the game was not in fullscreen and at the left top of the page. I can´t give an X and Y position to the scores, because of the difference in screen sizes.
How do I need to solve this?
Here's my HTML:
<html lang='en'>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<script type="text/javascript">
var scoreteen = 0;

document.getElementById('tululoogame').style.display = 'none';

document.getElementById('scoremutant').style.display = 'none';

document.getElementById('tululoogame').style.display = 'block';

i guess you have to resize your map_canvas as well.
so just add this to your resize()
//its maybe better to attach this handler to the window instead of the document
$(window).resize(function(){
$('#map_canvas').css("height",$(window).height());
$('#map_canvas').css("width",$(window).width());
google.maps.event.trigger(map, 'resize');
map.setZoom( map.getZoom() );
});
so you have track of the resizing of your browserwindow :)
Same things can be done using only CSS too. I'll put an example below, use this if you like.
.google-maps {
position: relative;
padding-bottom: 75%;
height: 0;
overflow: hidden;
}
.google-maps iframe {
position: absolute;
top: 0;
left: 0;
width: 100% !important;
height: 100% !important;
}
<div class="google-maps">
<iframe src="https://www.google.com/maps/yourmapsblah" width="765" height="500" frameborder="3" style="border:0" allowfullscreen></iframe>
</div>
I am having a Html hyperlink. I need to link this hyperlink to another page.When I place the mouse over the link. It should show the image.
how to do this
That depends on where you need to display the image. If you are looking for something along the lines of an icon next to or behind the link, you could accomplish this through CSS using a background image on the hover state of the link:
a:link
{
background-image:none;
}
a:hover
{
background-image:url('images/icon.png');
background-repeat:no-repeat;
background-position:right;
padding-right:10px /*adjust based on icon size*/
}
I did this off the top of my head, so you may need to make some minor adjustments.
If you wanted to show an image somewhere else on the page, you could accomplish that using javascript to hide/show the image on the link's mouseover event.
If this doesn't solve your problem, maybe you could supply some additional information to help guide everybody to the right answer.
You can do this easily with jquery:
$("li").hover(
function () {
$(this).append($("<img src="myimage.jpg"/>"));
},
function () {
$(this).find("img:last").remove();
}
);
Some more comprehensive examples which are actually tested:
http://docs.jquery.com/Events/hover
you can do this using javascript..
This will create a square that follows your mouse on div or element hover.
Create a .js file with those contents here:
var WindowVisible = null;
function WindowShow() {
this.bind = function(obj,url,height,width) {
obj.url = url;
obj.mheight = height;
obj.mwidth = width;
obj.onmouseover = function(e) {
if (WindowVisible == null) {
if (!e) e = window.event;
var tmp = document.createElement("div");
tmp.style.position = 'absolute';
tmp.style.top = parseInt(e.clientY + 15) + 'px';
tmp.style.left = parseInt(e.clientX + 15) + 'px';
var iframe = document.createElement('iframe');
iframe.src = this.url;
iframe.style.border = '0px';
iframe.style.height = parseInt(this.mheight)+'px';
iframe.style.width = parseInt(this.mwidth)+'px';
iframe.style.position = 'absolute';
iframe.style.top = '0px';
iframe.style.left = '0px';
tmp.appendChild(iframe);
tmp.style.display = 'none';
WindowVisible = tmp;
document.body.appendChild(tmp);
tmp.style.height = parseInt(this.mheight) + 'px';
tmp.style.width = parseInt(this.mwidth) + 'px';
tmp.style.display = 'block';
}
}
obj.onmouseout = function() {
if (WindowVisible != null) {
document.body.removeChild(WindowVisible);
WindowVisible = null;
}
}
obj.onmousemove = function(e) {
if (!e) e = window.event;
WindowVisible.style.top = parseInt(e.clientY + 15) + 'px';
WindowVisible.style.left = parseInt(e.clientX + 15) + 'px';
}
}
}
Then in your html do the following:
Include the .js file <script type="text/javascript" src="myfile.js"></script>
Put in your web page:
<script type="text/javascript">
var asd = new WindowShow();
asd.bind(document.getElementById('go1'),'IMAGE URL HERE!',400,480);
</script>
Here is a full implementation in a HTML:
<html>
<head>
<title>test page</title>
<style>
div.block { width: 300px; height: 300px; background-color: red; }
iframe { border: 0px; padding: 0px; margin: 0px; }
</style>
<script type="text/javascript" src="window_show.js"></script>
</head>
<body>
<div id="go1" style="background-color: red; width: 200px; height: 200px;"></div>
<script type="text/javascript">
var asd = new WindowShow();
asd.bind(document.getElementById('go1'),'IMAGE URL HERE!',400,480);
</script>
</body>
bye bye!
