CSS Zoom effect on load - hide DIV/Image loading latency

I have a web site with a lot of images, I already have lazy-loading but I wish to add some
effects when the images loads
I was looking to reproduce the "zoom" effect when the image is "loading", something like here:
https://masonry.desandro.com/
Please, have a look at this one:
https://tympanus.net/Development/GridLoadingEffects/index8.html
You will notice that there is no effect when the image are already loaded.
I try to hide the 'load latency' when loading an image from the server.
Maybe the animation is not the right trick!
The goal is to have the load softer, now it loads like any image, but the effect is not very nice.
(you can check www.socloze.com for review).
Do you think we can do this in pure CSS (without JS)?

You can add initial animation:
.img-anim {
width: 100px;
height: 100px;
background-image: url('https://lh3.googleusercontent.com/proxy/Dv3m6UV5rC0KL0or-iOT-6i1I4i4I3CXNh-XU0WZ5-yG_vbYme6A8NhIasiwLon0td1DGbVFBDOEwi3LK7gegowFkjQEiJpPBg');
background-position: center;
background-size: 100%;
background-repeat: no-repeat;
animation-name: scale-in;
animation-duration: .4s;
}
#keyframes scale-in {
0% {
background-size: 0%;
}
100% {
background-size: 100%;
}
}
<div class="img-anim"></div>

You can create initial animation usings css but thats as far as u go, if you need things to pop up as you scroll down then check AOS

How to make images position properly on lower resolutions without bootstrap?

I am trying to make website which has some icons on map. The problem is, that when I am making window smaller icons have wrong position, and they are in different places than I would like them to be. Also I cannot use bootstrap to position them. Only HTML, CSS and JS/jQuery.
Option 1: https://imgur.com/a/ifKFXRL
Option 2: https://imgur.com/a/R5DmQbt
I have already tried thing like:
min-height:100%;
min-width:100%;
}
#media only screen and (max-width: 1000px) {
body .background .foodini-logo img{
width:15%;
height:15%;
margin-top: 10%
margin-left:12%;
}
}
It only changed it for a while, because with resolution getting lower I had to add another media like every 100px, which is not an option for every icon I think.
html{
height:100%;
width:100%;
}
body {
background: url("../img/bg.png") no-repeat center center fixed;
background-size: cover;
background-color:rgb(178,212,238);
}
.
.
.
body .background .foodini-logo{
margin-top:15%;
margin-left:17%;
}
body .background .haps-logo {
margin-top: 35%;
margin-left: 23%;
}
I would like to have this icons be all the time as in option 1, no matter what resolution user will have on his screen.

The tricky part is that you're trying to use background-size: cover with position: relative logos. Cover is going to grow and shrink based on how large the elements are inside it. But you don't want that.
.background {
background: url("../img/bg.png") no-repeat center center fixed;
background-size: 100% auto;
background-color: rgb(178,212,238);
padding-bottom: 65%;
}
Changing the background-size to 100% auto will make the background 100% wide without stretching. I also added padding to make sure the container will keep the correct height ratio, since we're going to make the logo position: absolute so they don't conflict with each other.
.logo {
position: absolute;
transform: translate(-50%, -50%);
}
.haps-logo {
top: 35%;
left: 23%;
}
I added transform so the logos are centered on their position, rather than being pinned to the top-left of the logo. A bit easier in my opinion, but not required.
If you post a codepen or jsfiddle link with your code we can make sure it works, but otherwise, you can adapt this to your current setup.

instagram style explore page image list with CSS

I am trying to make a instagram style explore page but i have one question here. I have created this DEMO from codepen.io .
In this demo you can see the images. The images width and height is different not a same. I want to crop that images with CSS Like this DEMO page.
The difference between the first and second demo
First demo :
.exPex {
width: 100%;
}
Second Demo:
.exPex {
width: 200%;
}
So second demo working just in crome but this is not good idea i think. Anyone can tell me, How do I obtain the results of their second demo?

You could set the images up as background images and use background-size: cover; to get the effect that you're looking for (DEMO). This has the downside that your users will not be able to right-click or drag the images (to save them, etc.) as they might be expecting to do.
HTML for an example image:
<div class="_jjzlb" style="background-image:url('http://mihangallery.ir/wp-content/uploads/2015/11/Almost-Home-Wallpapers.jpg');">
</div>
CSS:
._jjzlb {
position: relative;
padding-top: 100%;
width: 100%;
overflow: hidden;
margin: 1px;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
/* Optional centered background */
background-position: center;
}
If this downside is not acceptable, you could also put hidden images on top of the backgrounds so that they will work like the user expects.
HTML for an example image with normal image mouse interactions:
<div class="_jjzlb" style="background-image: url('http://mihangallery.ir/wp-content/uploads/2015/11/Almost-Home-Wallpapers.jpg');">
<img src="http://mihangallery.ir/wp-content/uploads/2015/11/Almost-Home-Wallpapers.jpg" class="exPex">
</div>
CSS to hide the image on top:
.exPex {
position: absolute;
display: block;
left: 0;
right: 0;
top: 0;
bottom: 0;
width: 100%;
height: 100%;
opacity:0;
}
And here is a DEMO with the images, interacting with the user like you might expect them to.
EDIT: As pointed out by #GCyrillus, there are downsides to using a background image rather than keeping the images in the content of the page. These might include search engines and screen readers failing to recognize the image. I do not have an exhaustive list of the downsides but depending on your application it may be worth investigating.

you may use transform :
.exPex {
position: absolute;
left: 0;
top: 0;
min-width:100%;
margin: 0;
transform: scale(2);
transform-origin: 0 40px;
}
http://codepen.io/gc-nomade/pen/jrbPRy

if you define a dimension to the image the aspect ratio will also be included. The best way is to put your image inside a div and declare the size of images that way you will be able also to crop images.

Well it might seem obvious but you could just put a fixed width to it ? Try to change width: 100% with width: 400px on .exPex for example.

Sliding Full width div in CSS Or Javascript

I have been looking around the internet for a while to find a good library or way of making a mobile full width/height div
And when I click a button it swipes to the right revealing another div
with new content, and pushing the current div to the left ( or right )
The blue box is my viewport, mobile in this case
Here's a crappy illustration to show what I mean
I have tried using CSS ( with semi-success ) I can reveal another div using
.slide {
position: absolute;
width: 100%;
height: 100%;
transition: transform .5s ease-in-out;
}
#slide-options {
background: #eee;
transform: translate(100%, 0);
}
#slide-options.active {
transform: translate(0,0);
}
But it's just sliding over the 1st div, not pushing it along
Any idea's or existing libraries?
Thank you!

Submit button disapears on hover and then reapears

So I'm using CSS :hover to replace a submit button background. When I mouse over the button the old background image disappears (so it looks like nothing is there) for a moment and then reappears with the new background. I thought that perhaps the button image file size was too large but its only 1.4kb. Is there a way to prevent this, caching or pre-loading, or something along those lines?

Is this only on the initial page display / hover?
This will be because the image file is only loaded on request - i.e. the hover action.
To avoid this, both button states should be stored in a single file. You then just need to adjust the background-position property to display the correct half of the image for it's current state.
Here's a rough example (note that button.png contains both image states and is 40 pixels high):
button {
background-image: url(button.png);
width: 60px;
height: 20px;
background-position: 0 0;
}
button:hover {
background-position: 0 -20px;
}

You could, maybe, use a technique that's similar in intent, albeit not execution, to Bryn's answer, above.
.button {background-image: url(img/for/hover-state.png)
background-position: top left;
background-repeat: repeat-x;
background-color: #fff;
height: 1.5em;
width: 5em;
}
.button span
{background-image: url(img/for/non-hover-state.png);
background-position: top left;
background-repeat: repeat-x;
background-color: #000;
height: 1.5em;
width: 5em;
}
.button:hover span
{background-color: transparent;
background-image: none;
}
The similarity I mentioned is to have both images present on the document in order to avoid the hover-flicker. On hover of the button the background-image of the span will disappear, and reveal the hover state, rather than having to load it on-demand.
The bonus is that, although I specified the height/width above this technique will work for dynamic re-sizing, not relying on fixed-width sizes of images (or it's as fluid as your design can allow it to be).

It's because it takes time for the "hover" image to download before it displays. To prevent this, you can use a sprite image technique.
