I just started my first React project and I'm facing issues with CSS. I'm trying to make a card with a hover effect on it, ofund a nice one online but it ised nested css, I tried node-sass but didn't really worked. I converted the CSS code to plain CSS but I can't figure out the hover effects in the card!!

`

card:
<section >
        <a href="#" >
          <h3>01</h3>
          <h4>Portfolio Site.</h4>
          <p>My personal site using ReactJs.</p>
        </a>
      </section>

Card CSS: I know it's a mess!! sorry...
.page-contain {
  display: flex;
  min-height: 100vh;
  align-items: center;
  justify-content: center;
  background: #e7f3f1;
  border: 0.75em solid white;
  padding: 2em;
  font-family: "Open Sans", sans-serif;
}

.data-card {
  display: flex;
  flex-direction: column;
  max-width: 20.75em;
  min-height: 20.75em;
  overflow: hidden;
  border-radius: 0.5em;

  margin: 1em;
  padding: 2.75em 2.5em;
  box-shadow: 0 1.5em 2.5em -0.5em rgba(#000000, 0.1);
  transition: transform 0.45s ease, background 0.45s ease;
}
.data-card h3 {
  color: #2e3c40;
  font-size: 3.5em;
  font-weight: 600;

.data-card p {
  opacity: 0;

  font-weight: 600;
  line-height: 1.8;
  margin: 0 0 1.25em;
  transform: translateY(-1em);
  transition: opacity 0.45s ease, transform 0.5s ease-in;
}

.data-card .link-text {
  display: block;
  color: #753bbd;
  font-size: 1.125em;
  font-weight: 600;
  line-height: 1.2;
  margin: auto 0 0;
  transition: color 0.45s ease-in;
}

.data-card:hover {
  background: #753bbd;
  transform: scale(1.02);
}

.data-card h3:hover {
  color: #ffffff;
  border-bottom-color: #a754c4;
}

.data-card h4:hover {
  color: #ffffff;
}

.data-card p:hover {
  opacity: 1;
  transform: none;
}

.data-card .link-text:hover {
  color: #ffffff;
}

I want to apply the hover effects to all tags in the card section (.page-contain) when I hover over it, right now I have to hover on individual elements for them to act in hover state!!

CodePudding user response：

This selector .data-card h3:hover means: if I hover on h3, this and this should happen. What you want is this .data-card:hover h3which means: when I hover on data-card, the h3 should look like this and that. You should change other selectors similarly.
