I'm working on a site and wanted to vertically center this rollover image on the Welcome screen. The image is 100% horizontally but vertically its too short, so I was hoping to get equal space on both sides. Can anyone help me? heres a link to the welcome screen:

Thanks in advance.
yea sorry about that, probably dont need the preload code but here it is just in case:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>GiMMiC</title>
<script type="text/javascript">
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
</script>
<style type="text/css">
body {

}
</style>

<center>
<body onload="MM_preloadImages('http://i1055.photobucket.com/albums/s519/deepsoulvision/gimmic2000rollover_zps9d73f3a5.jpg')"><img src="http://i1055.photobucket.com/albums/s519/deepsoulvision/gimmic2000main_zpse8da217b.jpg" style="vertical-align:middle" alt="ENTER" name="Image1" width="100%" height="100%" border="0" id="Image1" />

If you don't need perfect support in IE8, then this would be easy to accomplish by setting the image as a background in CSS and use the background-size property to scale it. For example:
#bg {
display: block;
height: 1000px;
height: 100vh;
width: 100%;
background: url('http://i1055...1.jpg') center center / cover no-repeat;
}
#bg:hover {
background-image: url('http://i1055...rollover.jpg');
}
Then your markup would look something like this:
<a id='bg' href='/home.html'></a>
And if you only need to preload that one image, that can be done easily with a single line of JS:
<script>var img = new Image(); img.src='http://i1055...rollover.jpg';</script>
Or possibly use a grayscale filter in place of the rollover image (http://www.karlhorky.com/2012/06/cross-browser-image-grayscale-with-css.html)

I'm using Mapbox with wordpress.
I see that the popup by default has anchor position which generates css.
I can't manage to center the popup on click : for example, some of the popup are truncated when i open it because the map does'nt center on it.
I tried all the solutions i found here, none of them work. I'm not using Json but wordpress loop to display markers and put content in popups. I find no solutions for anything else than json .
So i just want to know if it's possible to entirely disable the position of the popup so that i can put it always on the map corner, whatever the marker I click..
EDIT
Finally I just changed some css to make the popup stick to the left of the map: I disabled the anchor default position with transform:none, I place it in the corner of the map container with top and left..And then I disabled the arrow around the popup.
.mapboxgl-popup{
transform:none !important;
top: 15%;
left: 10px;
}
.mapboxgl-popup-anchor-top .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-bottom .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-center .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-left .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-right .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-bottom-right .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-bottom-left .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-top-right .mapboxgl-popup-tip,
.mapboxgl-popup-anchor-top-left .mapboxgl-popup-tip{
display:none !important;
}
use this example from officail map box example :
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8' />
<title>Display a popup</title>
<meta name='viewport' content='initial-scale=1,maximum-scale=1,user-scalable=no' />
<script src='https://api.tiles.mapbox.com/mapbox-gl-js/v0.52.0/mapbox-gl.js'></script>
<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.52.0/mapbox-gl.css' rel='stylesheet' />
<style>
body { margin:0; padding:0; }
#map { position:absolute; top:0; bottom:0; width:100%; }
</style>
</head>
<body>
<div id='map'></div>
<script>
mapboxgl.accessToken = '<your access token here>';
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v9',
center: [-96, 37.8],
zoom: 3
});
var popup = new mapboxgl.Popup({closeOnClick: false})
.setLngLat([-96, 37.8])
.setHTML('<h1>Hello World!</h1>')
.addTo(map);
</script>
</body>
</html>
and you can see the example result on the below link :

Hi in the below code I am using in my website but it was displaying like this
http://rushdainfotech.in/contact.php
Can any one please help me
<div id="google_translate_element"></div><script type="text/javascript">
function googleTranslateElementInit() {
new google.translate.TranslateElement({pageLanguage: 'en'}, 'google_translate_element');
}
</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
The google translate aspect seems to be working fine. However, there is a global style that you have:
img {
max-width: 100%;
height: auto;
width:100%;
}
Simply comment out or move it to be class based the width: 100% and it should look fine.
I have an accordion menu that I have tweaked to suit my needs. My last stumbling block is that I have an image (see attached image) of a FedEx Courier that I need to lay on top of the menu and yet still allow users to click through it to activate (access) the accordion menu. The image is a separate image that is set to the desired alpha as created in Photoshop. The file is merely a snapshot of how it would look if it was the way I wanted it.
If this is even possible, what code would I use and exactly where would I place it? If in the CSS file, where does it go and between which lines?
Original full size Image file
You can apply the css:
pointer-events: none;
to the image above the links.
See fiddle https://jsfiddle.net/4zgcrkyz/
pointer-events: none; is a suitable solution if you do not need to care about IE < 11. More info on compatibility here.
Alternatively you can use elementFromPoint() which has compatibility IE > 5.5
The following trick allow you to select under your cover image without using pointer-events: none;
https://jsbin.com/tuhotagize/edit?html,output
Explanation:
At click on cover image.
Hide cover image temporary.
Get mouse coordinates.
Get HTML element under that mouse coordinates (so you know what under the cover).
Trigger click event on that HTML element.
Show cover image again.
Another alternative solution to your problem, which does not include any JS is:
Trim your image in PhotoShop as should appear inside the menu. Use CSS background-image property on it
Use the courier FedEx image only as CSS background-image the body of your page.
You can achieve the same visual effect using only CSS.

First of all many thanks for this page, it has been helping me a lot! But at this point I have a question where I cannot find an answer that fits what I want (maybe it cannot be achieved the way I am doing it).
I want to have a link with a static image, and when the user moves the cursor over the link I want an animated gif to play (the anim gif is set to not loop, so it only plays once). And when the user moves out go back to the static image and if the user goes in again, the gif should play again from the beginning.
I am using html5 combined with CSS to create my web (which I am using to learn at the same time). I did programing in the past with C++ and similar, but never on a web context.
So far this is what I tried:
CSS:
.img-acu
{
float: left;
width: 450px;
height: 264px;
background:transparent url("acu.gif") center top no-repeat;
}
.img-acu:hover
{
background-image: url("acusel.gif");
}
HTML:
But nothing at all appears :(
The weird thing is, I used this same example with two static images (png format) and it worked fine, but for some reason with the animated gif it doesn't want to work.
The I tried this:
CSS:
#test
{
width: 450px;
height: 264px;
background-image: url("acu.gif");
background-repeat: no-repeat;
background-position: left;
margin-left: 75px;
}
#test:hover
{
background-image: url("acusel.gif");
}
HTML:
<div id="test"></div>
And that works perfectly, it is just the link doesn't work and when the animated gif reaches the last frame, it never resets (unless I reload the page).
Do you know if there is any way to achieve this properly in HTML5 + CSS? should I use javascript or php?
I would really appreciate any help!
Thanks a lot!!
That can be achieved by use a static image and your gif image(Hey, that how 9gag do it!)
A basic script could be somthing like that:
<img id="myImg" src="staticImg.png" />
<script>
$(function() {
$("#myImg").hover(
function() {
$(this).attr("src", "animatedImg.gif");
},
function() {
$(this).attr("src", "staticImg.jpg");
}
);
});
</script>
Hopefully this simple way can help someone:
<img class="static" src="https://lh4.googleusercontent.com/-gZiu96oTuu4/Uag5oWLQHfI/AAAAAAAABSE/pl1W8n91hH0/w140-h165-no/Homer-Static.png"><img class="active" src="https://lh4.googleusercontent.com/i1RprwcvxhbN2TAMunNxS4RiNVT0DvlD9FNQCvPFuJ0=w140-h165-no">
Then add the following CSS:
.static {
position: absolute;
background: white;
}
.static:hover {
opacity: 0;
}
This should hopefully help some people. I got the code from a codepen and decided some stack overflow users may find it helpful. If you would like to view the original codepen, visit here: CodePen
The approach you took did not work because CSS will not change the background on < a >. Solving this can be done entirely with vanilla JS + HTML. The trick is to place:
<div class="img-acu">
inside of:
(insert here)
All that's left is to have CSS target the div. That way, you can set the static background, which then changes on :hover
Here's a fiddle showing this in action (or you can fiddle with this: https://jsfiddle.net/lyfthis/yfmhd1xL/):
.img-acu
{
float: left;
width: 250px;
height: 132px;
background:transparent url("https://i.imgur.com/7r91PY3.jpeg") center top no-repeat;
background-size: 125%;
}
.img-acu:hover
{
background-image: url("https://media.giphy.com/media/QMkPpxPDYY0fu/giphy.gif");
}
<!-- Don't do this:

window.onload = function() {
var c = document.getElementById("canvas");
var ctx = c.getContext("2d");
var img = document.getElementById("gif");
ctx.drawImage(img, 0, 0);
}
$(document).ready(function() {
$("#wrapper").bind("mouseenter mouseleave", function(e) {
$("#canvas").toggleClass("hide");
});
});

I have a few images on my page. I'm finding that the page starts to render before the images have been loading (which is good), but that the visual effect is not great. Initially the user sees this:
--------hr--------
text
Then a few milliseconds later the page jumps to show this:
--------hr--------
[ ]
[ image ]
[ ]
text
Is there a simple way that I can show a grey background image of exactly the width and height that the image will occupy, until the image itself loads?
The complicating factor is that I don't know the height and width of the images in advance: they are responsive, and just set to width: 100% of the containing div. This is the HTML/CSS:
<div class="thumbnail">
<img src="myimage.jpeg" />
<div class="caption">caption</div>
</div>
img { width: 100% }
Here's a JSFiddle to illustrate the basic problem: http://jsfiddle.net/X8rTB/3/
I've looked into things like LazyLoad, but I can't help feeling there must be a simpler, non-JS answer. Or is the fact that I don't know the height of the image in advance an insurmountable problem? I do know the aspect ratio of the images.
Instead of referencing the image directly, stick it within a DIV, like the following:
<div class="placeholder">
<div class="myimage" style="background-image: url({somedynamicimageurl})"><img /></div>
</div>
Then in your CSS:
.placeholder {
width: 300;
height: 300;
background-repeat: no-repeat;
background-size: contain;
background-image: url('my_placeholder.png');
}
Keep in mind - the previous answers that recommend using a div background approach will change the semantic of your image by turning it from an img into a div background. This will result in things like no indexing of these images by a search crawler, delay in loading of these images by the browser (unless you explicitly preload them), etc.
A solution to this issue (while not using the div background approach) is to have a wrapper div to your image and add padding-top to it based on the aspect ratio of the image that you need to know in advance. The below code will work for an image with an aspect ratio of 2:1 (height is 50% of width).
<div style="width:100%;height:0; padding-top:50%;position:relative;">
<img src="<imgUrl>" style="position:absolute; top:0; left:0; width:100%;">
</div>
Of course - the major disadvantage of this approach is that you need to know the aspect ratio of the image in advance.
There is a really simple thing to check before you start looking into lazy-loading and other JavaScript. Make sure the JPEG images you are loading are saved with the 'progressive' option enabled!
This will cause them to load the image iteratively, starting with a placeholder that is low-resolution and faster to download, rather than waiting for the highest resolution data before rendering.
It's very simple...
This scenario allows to load a profile photo that defaults to a placeholder image.
You could load multi CSS background-image into an element. When an avatar photo fails, the placeholder image appears default of div.
If you're using a div element that loads via a CSS background-image, you could use this style:
#avatarImage {
background-image: url("place-holder-image.png"), url("avatar-image.png");
}
<div id="avatarImage"></div>
Feel free to copy this:
<script>
window.addEventListener("load", function () {
document.getElementById('image').style.backgroundColor = 'transparent';
});
</script>
<body>
<image src="example.example.example" alt="example" id="image" style="background-color:blue;">
</body>
I got this from here: Preloader keeps on loading and doesnt disappear when the content is loaded.
Apart from all solutions already mentioned, the last solution would be to hide the document until everything is loaded.
window.addEventListener('load', (e) => {
document.body.classList.add('loaded');
});
body {
opacity: 0;
}
body.loaded {
opacity: 1;
}
<div id="sidebar">
<img src="http://farm9.staticflickr.com/8075/8449869813_1e62a60f01_b.jpg" />

</div>
Or show some animation while everything is loading:
window.addEventListener('load', (e) => {
document.body.classList.add('loaded');
});
.loader {
border: 16px solid #f3f3f3;
border-radius: 50%;
border-top: 16px solid #3498db;
width: 70px;
height: 70px;
-webkit-animation: spin 2s linear infinite;
/* Safari */
animation: spin 2s linear infinite;
position: absolute;
left: calc(50% - 35px);
top: calc(50% - 35px);
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
body :not(.loader) {
opacity: 0;
}
body .loader {
display: block;
}
body.loaded :not(.loader) {
opacity: 1;
}
body.loaded .loader {
display: none;
}
<div class="loader"></div>

The only thing I can think of, to minimize the jump effect on your text, is to set min-height to where the image will appear, I would say - set it to the "shorter" image you know of. This way the jump will be less evident and you won't need to use lazyLoad or so... However it doesn't completely fix your problem.
Here's one naive way of doing it,
img {
box-shadow: 0 0 10px 0 rgba(#000, 0.1);
}
You can manipulate the values, but it creates a very light border around the image that doesn't push the contents. Images can load at whatever time they want, and you get a good user experience.
Here is what I did with Tailwind CSS, but it's just CSS:
img {
#apply bg-no-repeat bg-center;
body.locale-en & {
background-image: url("data:image/svg+xml;utf8,<svg width='100' height='100' viewBox='0 0 100 100' xmlns='http://www.w3.org/2000/svg'><text x='50%' y='50%' style='font-family: sans-serif; font-size: 12px;' dominant-baseline='middle' text-anchor='middle'>Loading…</text></svg>");
}
body.locale-fr & {
background-image: url("data:image/svg+xml;utf8,<svg width='100' height='100' viewBox='0 0 100 100' xmlns='http://www.w3.org/2000/svg'><text x='50%' y='50%' style='font-family: sans-serif; font-size: 12px;' dominant-baseline='middle' text-anchor='middle'>Chargement…</text></svg>");
}
}
You can find the width and height of the images in the developer tools console, for example in Chrome you can click the cursor icon in the developer tools console and when you hover on the page it will highlight all the properties of the elements in the page.
This will help you find the width and height of the images, because if you hover on top of your images it will give you the dimensions of the image and other more properties. You can also make an individual div for each image and make the div relative to the images width and height. You can do it like this:
The main div will contain the images and also the background-div which is below the image.
HTML:
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<div class=".mainDiv">
<div class="below"></div>
<img src="https://imgix.bustle.com/uploads/image/2020/2/13/da1a1ca4-95ec-40ea-83c1-4f07fac8b9b7-eqb9xdwx0auhotc.jpg" width="500"/>
</div>
</body>
</html>
CSS:
.mainDiv {
position: relative;
}
.below {
position: absolute;
background: #96a0aa;
width: 500px;
height: 281px;
}
img {
position: absolute;
}
The result will be that .below will be below the image and so when the image has trouble loading the user will instead see the grey .below div. You cannot see the .below div because it is hidden below the image. The only time you will see this is when the loading of the image is delayed. And this will solve all your problems.
I have got a way. But you will need to use JavaScript for it.
The HTML:
img = document.getElementById("img")
text = document.getElementById("text")
document.addEventListener("DOMContentLoaded", () => {
img.src = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAOEAAADhCAMAAAAJbSJIAAAAA1BMVEWIiIhYZW6zAAAASElEQVR4nO3BgQAAAADDoPlTX+AIVQEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAADwDcaiAAFXD1ujAAAAAElFTkSuQmCC";
text.innerHTML = "Loaded but image is not";
});
window.onload = function() {
img.src = "https://media.geeksforgeeks.org/wp-content/uploads/20190913002133/body-onload-console.png";
text.innerHTML = "Image is now loaded";
};
#img {
width: 400px;
height: 300px;
}
<hr>
<img id="img" src="https://media.geeksforgeeks.org/wp-content/uploads/20190913002133/body-onload-console.png">
