I want background image to keep moving from left to right.
Any idea how can I do that ? I tried to use code from stackoverflow, didnt work, I tried to google, didnt work.
This is my code. There is nothing about the moving background I am just placing it here because it might help. I´d like to know why any code never worked.

I have the website on xampp server for now, later I will go to node.js server.
this is my file tree.
please remove this code from body
body {
background-color: #232B2B;
background-image:url('../web/css/cave-background.png');
background-position:top;
background-repeat:no-repeat;
color:#FFFFFF;
}
you can set the following div code inside the body tag
div{
background-color: #232B2B;
background-image:url('../web/css/cave-background.png');
background-position:top;
background-repeat:no-repeat;
}

what I want to see the result is 2 set of split view screen (or more), one is vertical, one is horizontal, but in the same javascript file. If it's possible to do in a single JavaScript file will be good
I tried to use this one to make it but it seems like not how to make that.

thank you for reading so far, please help me if you're able to! If any information is needed, please tell me below and I'll provide it as soon as possible.
I have an inner circle which tracks the position of my pointer, Now I want the circle color to change when it hovers on the h2 tag.
can anyone help??
I have tried searching few places but all were on "mouseover".
note: only when the inner-circle hovers on h2 not the mouse pointer, the inner circle's color should change.

var e_pos = ele.getBoundingClientRect();
var h_pos = hea[1].getBoundingClientRect();
if(e_pos.bottom>=h_pos.top && e_pos.top<=h_pos.bottom && e_pos.right>=h_pos.left && e_pos.left<=h_pos.right){
ele.style.backgroundColor= "rgba(0,0,0,0.5)";
}else{
ele.style.backgroundColor= "#af4b23";
};
}
var display = function()
{
//console.log("done");
hea[0].style.display="inline-block";
hea[1].style.display="none";
}
var hide = function()
{
//console.log("done hiden");
hea[0].style.display="none";
hea[1].style.display="inline-block";
}
body.addEventListener("mousemove",function(){ move(event) },false);
body.addEventListener("mouseout",display,false);
body.addEventListener("mouseover",hide,false);
})();
in this answer i set background-color after setting left and top of ele. also i have removed two last eventListeners.
Look at the result online and change it yorself!
the border is added to detect h2's bounds.
When I practice waterfall flow layout, it has a problemlike this:
When the page is first loaded or I click [refresh] or press [F5], it looks bad. Each column of the images stacks!
But when I press [enter] in address bar or scroll with mouse, it looks good.
So how can I solve the problem? Thanks a lot!

I am just learning JavaScript and for some reason this simple (Example 1 from Chapter One) example is not working (Jon Duckett's JavaScript and Jquery book) in any of my browsers: FireFox, IE, and Chrome. I made sure JavaScript is turned on. I also put noscript tags in my index.html file to make sure I had JavaScript on. My jsFiddle works perfectly, but nothing in my browsers. Here is my jsFiddle with everything I have in my Atom editor. My links are correct because I copied the full path and then pasted it into the src. I then deleted all the C:\users....... until I got into the folder with all of the files to end up with what is in the jsFiddle.

You want to add the script tag at the end of your html. The element greeting doesn't exist, when you are executing it.

Or you leave it in the head and wrap the script into
addEventListener("readystatechange", function () {
if (document.readyState === "interactive") {
var today = new Date();
var hourNow = today.getHours();
var greeting;
if (hourNow > 18) {
greeting = 'Good evening!';
} else if (hourNow > 12) {
greeting = 'Good afternoon!';
} else if (hourNow > 0) {
greeting = 'Good morning!';
} else {
greeting = 'Welcome!';
}
document.getElementById("greeting").innerHTML = greeting;
}
}, false);
It is wonderful you use document.getElementById, instead of document.write!
I had been trying to animate a .png file with JavaScript while following this method. This is the .png file that I want to animate. I want the animated logo to be right by "Cupquake," but the logo doesn't even show up, let alone animate. However, changing "span class=logoCquake" in HTML to a div class displays the logo, but it is below the text.
My JavaScript file:
var scrollUp = (function () {
var timerId;
return function (height, times, element) {
var i = 0;
timerId = setInterval(function () {
if (i > times)
i = 0;
element.style.backgroundPosition = "0px -" + i * height + 'px';
i++;
}, 100);
};
})();
scrollUp(130, 30, document.getElementByClass('logoCquake'))

Tried again, but with the second method listed here, still nothing. These are my current HTML and JS codes:
JS:
function SpriteAnim (options) {
var timerId,
i = 0,
element = document.getElementByClass(options.elementClass);
element.style.width = options.width + "px";
element.style.height = options.height + "px";
element.style.backgroundRepeat = "no-repeat";
element.style.backgroundImage = "url(" + options.sprite + ")";
timerId = setInterval(function () {
if (i >= options.frames) {
i = 0;
}
element.style.backgroundPosition = "0px -" + i * options.height + "px";
i ++;
}, 100);
this.stopAnimation = function () {
clearInterval(timerId);
};
}
var cupcake = new SpriteAnim({
width: 130,
height: 112,
frames: 30,
sprite: "..\imgz\logo\logoCquake.png",
elementClass : "logoCquake"
});

I believe 'span' tag being an inline element it either needs a 'display: block' property or 'float: left', i tried your code and it worked for me after i added 'display: block' to the 'span' tag with class 'logoCquake'. Hope this helps you.
Note: if you use 'display: block' the span will move to new line and if you use 'float: left' the 'span' tag will move to the left of the text.
