I'm making a car research/ranking website using React. Coming to the issue, I have 3 cards, with content on it once you hover over it.

It works perfectly well in desktops, but it doesn't properly show content in smaller devices: it overflows to the other section.

To fix this, I have added a media query to it, but it doesn't work either.

Please check my code:

.sec2 {
  height: 100vh;
  width: 100%;
  color: white;
  display: flex;
  justify-content: center;
  align-items: center;
  flex-direction: column;

  background: linear-gradient(to left, rgba(0, 0, 0, 0.7), rgba(0, 0, 0, 0.7)),
    url(https://static.feber.se/article_images/48/81/62/488162_1920.jpg)
      no-repeat top center;
}



.wrapper {
  display: flex;
  width: 90%;
  justify-content: space-around;
}

.card {
  width: 350px;
  height: 370px;
  border-radius: 15px;
  padding: 1.5rem;
  position: relative;
  object-fit: fill;
  display: flex;
  align-items: flex-end;
  transition: 0.4s ease-out;
  box-shadow: 0px 7px 10px rgba(0, 0, 0, 0.5);
}
.card:hover {
  transform: translateY(20px);
}
.card:hover:before {
  opacity: 1;
}
.card:hover .info {
  opacity: 1;
  transform: translateY(0px);
}
.card:before {
  content: "";
  position: absolute;
  top: 0;
  left: 0;
  display: block;
  width: 100%;
  height: 100%;
  border-radius: 15px;
  background: rgba(0, 0, 0, 0.6);
  z-index: 2;
  transition: 0.5s;
  opacity: 0;
}
.card img {
  width: 100%;
  height: 100%;
  object-fit: cover;
  position: absolute;
  top: 0;
  left: 0;
  border-radius: 15px;
}
.card .info {
  position: relative;
  z-index: 3;
  color: white;
  opacity: 0;
  transform: translateY(30px);
  transition: 0.5s;
}
.card .info h1 {
  margin: 0px;
  font-size: 2rem;
}
.card .info p {
  letter-spacing: 1px;
  font-size: 15px;
  margin-top: 8px;
}
.card .info button {
  padding: 0.6rem;
  outline: none;
  border: none;
  border-radius: 3px;
  background: white;
  color: black;
  font-weight: bold;
  cursor: pointer;
  transition: 0.4s ease;
}
.card .info button:hover {
  background: dodgerblue;
  color: white;
}

@media only screen and (min-width: 600px) and (max-width: 768px) {
  .wrapper {
    flex-direction: column;
    justify-content: center;
    align-items: center;
  }

  .card {
    height: 270px;
    padding: 1rem;
    width: 250px;
    margin-bottom: 10px;
  }

  .card .info h1 {
    font-size: 1rem;
  }

  .card .info p {
    font-size: 15px;
  }

  .card .info button {
    padding: 0.4rem;
    font-weight: normal;
    font-size: 12px;
  }
}

@media (max-width: 600px) {
  .wrapper {
    flex-direction: column;
    justify-content: center;
    align-items: center;
  }

  .card {
    height: 15%;
    padding: 0.3rem;
    width: 180px;
    margin-bottom: 5px;
  }

  .card .info h1 {
    font-size: 1rem;
  }

  .card .info p {
    font-size: 10px;
  }

  .card .info button {
    padding: 0.3rem;
    font-weight: normal;
    font-size: 10px;
  }
}

CodePudding user response：

• first add the margin: auto in .wrapper class and some margin: 5px; to .card class because this make content in the center and looks good.

.wrapper {
  display: flex;
  width: 90%;
  margin: auto;
  justify-content: space-around;
}
.card {
  /* your code */
  margin: 5px;
}

• Now, add just update margin: 15px; of all .card instead of margin-bottom
