CodePudding user response:

Css: i have a div with display flex which makes img and the span align horizontally, inside my span i have a h1 and a p tag.

for the h1 i have set some css properties and a transformY(10px) that means i am moving it up 10px from its original position.and a transition with time and animation type.

for the p i have also set some properties and a opacityof 0;

then i am just saying if my wrapper has a class of online in it then do this to h1 and p.

i am toggling that online class with a button for demo purpose. but in real life it can be with anything.

let wrapper = document.querySelector(".wrapper");
let btn = document.querySelector(".btn");

btn.addEventListener("click",()=>{
wrapper.classList.toggle("online")
})
.wrapper {
  width: 510px;
  height: 130px;
  background-color: #017d68;
  display: flex;
  align-items: center;
  padding: 10px;
  gap: 30px;
}

img {
  height: 120px;
  border-radius: 100%
}

p {
  font-size: 20px;
  color: white;
  opacity: 0;
  transition: all 0.25s ease-in-out;
}

h1 {
  font-family: Arial, Helvetica, sans-serif;
  color: white;
  transform: translateY(10px);
  transition: all 0.25s ease-in-out;
}
.wrapper.online h1{
  transform: translateY(-10px);
}
.wrapper.online p {
  opacity: 1;
}
