The parent div cannot be centered because the left margin of the child div is negative.

Question

I created the following div, but because I'm using a negative left margin to offset the icon, I can't center the entire div. We can get away with it on desktop because you can't easily tell that the whole div is moved a little to the left, but on mobile the left side of the circular icon is cut off. How can I center the entire div?

.icon-text-box {
  border: 1px solid red;
}

.icon-box {
  background: #fff;
  border-radius: 33px;
  margin: 6rem auto;
  padding: 4rem 4rem 4rem 7rem;
  box-shadow: 0 3px 6px -2px rgb(0 0 0 / 20%), 0 6px 12px rgb(0 0 0 / 10%);
  position: relative;
  display: flex;
  align-self: center;
  max-width: 900px;
}

.icon-box p {
  font-size: 22px;
  margin-bottom: 0;
}

.icon-box-icon {
  position: absolute;
  left: -90px;
  overflow: hidden;
  display: flex;
  align-self: center;
  height: 177px;
}

.icon-box-icon img {
  border-radius: 40px;
}

<div class="container-fluid mw-972 icon-text-box">
  <div class="icon-box">
    <div class="icon-box-icon">
      <img src="https://www.freepnglogos.com/uploads/spotify-logo-png/spotify-simple-green-logo-icon-24.png" />
    </div>

Answer 1

Instead of auto margins, you can use a different idea to center while adding some margins on small screens

margin: 6rem max(90px,(100% - 900px)/2);

Full code:

.icon-text-box {
  border: 1px solid red;
}

.icon-box {
  background: #fff;
  border-radius: 33px;
  margin: 6rem max(90px,(100% - 900px)/2);
  padding: 4rem 4rem 4rem 7rem;
  box-shadow: 0 3px 6px -2px rgb(0 0 0 / 20%), 0 6px 12px rgb(0 0 0 / 10%);
  position: relative;
  display: flex;
}

.icon-box p {
  font-size: 22px;
  margin-bottom: 0;
}

.icon-box-icon {
  position: absolute;
  left: -90px;
  top: 50%;
  transform: translateY(-50%);
  overflow: hidden;
  display: flex;
  height: 177px;
}

.icon-box-icon img {
  border-radius: 40px;
}

If you want a margin on one side, also look like this:

.icon-text-box {
  border: 1px solid red;
}

.icon-box {
  background: #fff;
  border-radius: 33px;
  margin: 6rem max(0px,(100% - 900px)/2) 6rem max(90px,(100% - 900px)/2);
  padding: 4rem 4rem 4rem 7rem;
  box-shadow: 0 3px 6px -2px rgb(0 0 0 / 20%), 0 6px 12px rgb(0 0 0 / 10%);
  position: relative;
  display: flex;
}

.icon-box p {
  font-size: 22px;
  margin-bottom: 0;
}

.icon-box-icon {
  position: absolute;
  left: -90px;
  top: 50%;
  transform: translateY(-50%);
  overflow: hidden;
  display: flex;
  height: 177px;
}

.icon-box-icon img {
  border-radius: 40px;
}
