I have a CSS style for a button. I don’t know how to do it. I think it’s a bit too complicated and it’s not easy to make responsive adjustments. I would like to ask everyone how to write a button like this in CSS? thanks
.save_coin {
display: inline-block;
position: relative;
z-index: 3;
}
.save_coin::after {
content: "";
display: inline-block;
position: absolute;
background: #222;
border-radius: 32px;
padding: 26px 101px;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
#media (max-width: 768px) {
.save_coin::after {
border-radius: 38px;
padding: 38px 102px;
}
}

Answer 1

I think you can use outline attribute, work pretty good imo.
button {
padding: 10px 30px;
border-radius: 50px;
border: 2px solid white;
background-color: black;
color: white;
outline: 2px solid black;
}
button:hover {
background-color: white;
color: black;
}
<button>save</button>

You could try the box-shadow CSS property:
button {
cursor: pointer;
outline: none;
font-size: 30px;
/* 👇 outer line */
border: 5px solid black;
/* some very large number, to get a pill effect */
border-radius: 1024px;
padding: 30px 60px 30px 60px;
background: black;
color: white;
/* 👇 inner white line */
box-shadow: inset 0 0 0 3px white;
/* custom transition */
transition: 0.3s ease;
}
/* ignore this if you just want button design */
button:hover {
background: white;
color: black;
}
<button type="button">立即儲值</button>
