Scaling image with CSS Transition
What do you mean by "jumps"? Try this, jumps too?
section {
background-color: rgba(0, 0, 0, 0.701961);
width: 400px;
height: 400px;
}
div {
position: absolute;
top: 120px;
left: 120px;
width: 160px;
height: 160px;
background-color: red;
-webkit-transition: -webkit-transform 0.4s;
transition: transform 0.4s;
}
div:hover {
-webkit-transform: scale(1.8) rotate(0.01deg);
transform: scale(1.8) rotate(0.01deg);
}
<section>
<div></div>
</section>
Also, you could try the variant with a container for an image (like in the first link of your question).
JSFiddle
.banner {
position: relative;
z-index: 1;
cursor: pointer;
border: 1px solid #dfe2e5;
background: #000;
width: 310px;
height: 150px;
-webkit-transition: border-color 0.1s;
transition: border-color 0.1s;
overflow: hidden;
}
.banner:hover {
border-color: #bdc1c5;
}
.banner__image-container {
overflow: hidden;
height: 100%;
}
.banner__image {
-webkit-transition: all 0.4s;
transition: all 0.4s;
}
.banner:hover .banner__image {
-webkit-transform: scale(1.15) rotate(0.01deg);
transform: scale(1.15) rotate(0.01deg);
opacity: 0.5;
}
<div class="banner">
<div class="banner__image-container">
<img class="banner__image" src="https://picsum.photos/310/150/?image=1022"/>
</div>
