Creating a option-choice landing page - html

Question

I want to create a landing page like a game. The visitor gets the option either to chose "Professioneel" or "Speels".
Telling it is easy but programming it is hard for me, so this is what I want:
2 div's with 2 different background-image when someone hover over one of the divs I want the background-image to scale (ONLY THE IMAGE) and the opacity placed on the div to change from 50% to 80%.
And a really nice future would be to display a snow falling gif over the image.
This is what I want to create:
Before
After:
What I have achieved till now is making the 2 divs with a background-image and I'm not even sure if that is the right way.
Can someone please help me out?
This is what happens when I hover with my current code: (the whole div scales, not only the image)
As an user asked, here some code:
#containerEntree {
height: 100vh;
width: 1920px;
padding-left: 0;
padding-right: 0;
}
#professioneelContainer {
background-color: red;
text-align: center;
width: 1920px;
height: 475px;
}
#speelsContainer {
background: red;
width: 100%;
height: 475px;
text-align: center;
}
.entreeTekst:hover {
transform: scale(1.2);
}
.entreeTekst {
width: 100%;
height: 100%;
position: relative;
transition: all .5s;
margin: auto;
}
.entreeTekst > span {
color: white;
/* Good thing we set a fallback color! */
font-size: 70px;
position: absolute;
}
<div class="container" id="containerEntree">
<div id="professioneelContainer">
<div class="entreeTekst">
<span>professioneel</span>
<img src="img/professioneel.jpg" />
</div>
</div>
<div id="speelsContainer">
<div class="entreeTekst">
<span>Speels</span>
<img src="img/speels.jpg" />
</div>
</div>
</div>
Please note that I'm still working on it so don't say that this (of course) won't work.

Answer 1

You can do this by using 2 divs with background images and use padding on the div to replicate the aspect ratio of the background image. Scale the image using background-size on :hover. Then use a pseudo element to create the color overlay and transition the opacity on :hover, then use the other pseudo element on top of that with the text and the "snow" gif as a background.
body {
width: 600px;
max-width: 80%;
margin: auto;
}
div {
background: url('https://static.tripping.com/uploads/image/0/5240/towns-funny-names-us_hero.jpg') center center no-repeat / 100%;
height: 0;
padding-bottom: 33.33333%;
position: relative;
transition: background-size .25s;
}
.speel {
background-image: url('http://www.luketingley.com/images/large/The-Punchbowl-Web-Pano.jpg');
}
div::after, div::before {
content: '';
position: absolute;
top: 0; left: 0; right: 0; bottom: 0;
}
div::before {
opacity: .5;
transition: opacity .25s;
}
.pro::before {
background: blue;
}
.speel::before {
background: red;
}
div::after {
display: flex;
align-items: center;
justify-content: center;
color: #fff;
font-family: sans-serif;
font-size: 1.5em;
font-weight: bold;
}
.pro::after {
content: 'PROFESSIONEEL';
}
.speel::after {
content: "SPEELS";
}
div:hover::after {
background: url('https://media.giphy.com/media/26BRyql7J3iOx875u/giphy.gif') center center no-repeat / cover;
}
div:hover::before {
opacity: 0.8;
}
div:hover {
background-size: 150%;
}
<div class="pro">
</div>
<div class="speel">
</div>

You can simply increase the background-size: height width; and opacity: value; property when you hover over an element. You can, if you want to, add some transition to make it smooth. This only scales the background image, not the div itself.
#d {
background-image: url(https://cdn.pixabay.com/photo/2016/10/29/20/52/cincinnati-1781540_960_720.png);
height: 200px;
width: 200px;
background-size: 100px 100px;
background-repeat: no-repeat;
background-position: center;
/*To make the transistion smooth*/
-o-transition:.5s;
-ms-transition:.5s;
-moz-transition:.5s;
-webkit-transition:.5s;
transition:.5s;
opacity: 0.5;
}
#d:hover {
background-size: 110px 110px;
opacity: 0.8;
}
<div id='d'>
</div>
