I’m having trouble centering my container’s item.

I need to align the third item to the center using display: grid.

I’ve already tried to use flexbox, but it looks worse for a responsive website.

.projetos {
  flex-direction: column;
  padding: 3rem 3%;
  text-align: center;
  justify-content: center;
}

.projetos-container {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  gap: 2rem;
  text-align: center;
}

.projetos-box img {
  width: 100%;
  max-width: 40rem;
  border-radius: 1rem;
}

<section class="projetos" id="projetos">
  <h2>Projetos <span>Recentes</span></h2>

  <div class="projetos-container">
    <div class="projetos-box">
      <img src="https://via.placeholder.com/200.jpg" alt="" width="500">
    </div>

    <div class="projetos-box">
      <img src="https://via.placeholder.com/200.jpg" alt="" width="500">
    </div>

    <div class="projetos-box">
      <img src="https://via.placeholder.com/200.jpg" alt="" width="500">
    </div>
  </div>
</section>

Convert the Container to flexbox by using display: flex;
Use flex-wrap: wrap to allow a break to a new row
Calculate the width of an element to create a 2 column layout to respect the gap
Center the items by using justify-content: center on the flex-container

:root {
  --gap: 2rem;
}

.projetos {
  flex-direction: column;
  padding: 3rem 3%;
  text-align: center;
  justify-content: center;
}

.projetos-container {
  display: flex;
  flex-wrap: wrap;
  gap: var(--gap) ; 
  justify-content: center;
}

.projetos-box {
  width: calc((100% - var(--gap)) / 2);
}

.projetos-box img {
  width: 100%;
  max-width: 40rem;
  border-radius: 1rem;
}

<section class="projetos" id="projetos">
  <h2>Projetos <span>Recentes</span></h2>

  <div class="projetos-container">
    <div class="projetos-box">
      <img src="https://via.placeholder.com/200.jpg" alt="" width="500">
    </div>

    <div class="projetos-box">

You may trick it and use transform but need to check a few things .

Is this standing alone on a row ? (an odd position)
Is this the last one ?
if both yes, move 50% aside of its own width + (for 2col) half of the gap set.

But it is basicly a flex job i would say 🙂

here is below a few test to demonstrate the idea and not mind about how many children you have in your grid.

.projetos {
  flex-direction: column;
  padding: 3rem 3%;
  text-align: center;
  justify-content: center;
  /* show me center */
  background:linear-gradient(to left,ivory 50%, silver 50%);
}

.projetos-container {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  gap: 2rem;
  text-align: center;
}

.projetos-box img {
  width: 100%;
  max-width: 40rem;
  border-radius: 1rem;
}

/* trick me */
.projetos-box:nth-child(odd):last-child {
  transform: translatex(calc(50% + 1rem));
}

If you dislike the transform trick, span this last odd element through both columns and give an auto margin.
