How to make this design responsive? - css

Question

I have tried to make an animation using CSS keyframes, but the design is breaking. How can I make it responsive without writing media queries, as it's just a simple animation code?
div {
font-family: "Comic Sans MS", sans-serif;
margin-left: 200px;
margin-top: 200px;
}
span {
color: white;
font-size: 35px;
padding: 14px 25px;
margin: 5px;
border-radius: 10px;
display: inline-block;
animation: move 0.8s infinite linear;
}
#keyframes move {
0% {
transform: translateY(0px);
opacity: 1.0;
}
50% {
transform: translateY(-50px);
opacity: 0.5;
}
100% {
transform: translateY(0px);
opacity: 1.0;
}
}
span:nth-child(1) {
animation-delay: 0.1s;
background-color: red;
box-shadow: 5px 5px 0 black;
}
span:nth-child(2) {
animation-delay: 0.2s;
background-color: blue;
box-shadow: 5px 5px 0 black;
}
span:nth-child(3) {
animation-delay: 0.3s;
background-color: green;
box-shadow: 5px 5px 0 black;
}
span:nth-child(4) {
animation-delay: 0.4s;
background-color: orangered;
box-shadow: 5px 5px 0 black;
}
span:nth-child(5) {
animation-delay: 0.5s;
background-color: springgreen;
box-shadow: 5px 5px 0 black;
}
span:nth-child(6) {
animation-delay: 0.6s;
background-color: blueviolet;
box-shadow: 5px 5px 0 black;
}
span:nth-child(7) {
animation-delay: 0.7s;
background-color: purple;
box-shadow: 5px 5px 0 black;
}
<div>
<span>W</span>
<span>E</span>
<span>L</span>
<span>C</span>
<span>O</span>
<span>M</span>
<span>E</span>
</div>

Without using a media query, you are limited to what you can do, but in this example, I've removed your set margin-left value and used a percentage instead and made the containing div a percentage width. I've also made the parent div a flex container - this will make sure things have a harder time wrapping on smaller screens.
I then used vw units for the font-size, so it will scale with the window width. Also the padding on the boxes needs to be set to percentages. You can play with it here:

div {
font-family: "Comic Sans MS", sans-serif;
margin: 200px auto 0;
width: 90%;
display: flex;
justify-content: center;
}
span {
color: white;
font-size: 4vw;
padding: 2% 3%;
margin: 5px;
border-radius: 10px;
display: inline-block;
animation: move 0.8s infinite linear;
}
#keyframes move {
0% {
transform: translateY(0px);
opacity: 1.0;
}
50% {
transform: translateY(-50px);
opacity: 0.5;
}
100% {
transform: translateY(0px);
opacity: 1.0;
}
}
span:nth-child(1) {
animation-delay: 0.1s;
background-color: red;
box-shadow: 5px 5px 0 black;
}
span:nth-child(2) {
animation-delay: 0.2s;
background-color: blue;
box-shadow: 5px 5px 0 black;
}
span:nth-child(3) {
animation-delay: 0.3s;
background-color: green;
box-shadow: 5px 5px 0 black;
}
span:nth-child(4) {
animation-delay: 0.4s;
background-color: orangered;
box-shadow: 5px 5px 0 black;
}
span:nth-child(5) {
animation-delay: 0.5s;
background-color: springgreen;
box-shadow: 5px 5px 0 black;
}
span:nth-child(6) {
animation-delay: 0.6s;
background-color: blueviolet;
box-shadow: 5px 5px 0 black;
}
span:nth-child(7) {
animation-delay: 0.7s;
background-color: purple;
box-shadow: 5px 5px 0 black;
}

<span>W</span>
<span>E</span>
