How to adjust div width with the siz of text inside it [duplicate]

Question

My idea is to make each element within divs that have the .main_content class, to have a width equal to the width of the text inside it. How do I this?

As you can see, the width of each one (span, h2, p and h6) is the same as the .main_content div. The red border demonstrates this.

So, how do I make the width of each div fit the text within those divs? (With only CSS)

.main_content {
   width: 100%;
  height: 400px;
  font-weight: 800;
}

.main_content > * {
  border: 1px solid red;
  display: block;
  margin-bottom: 30px;
  text-align: center; 
}

<div class="first_article">
  <div class="first_content">
    <div class="main_content">
       <span class="growth">Growth</span>

</div>

P: I've been trying to manually set the size of width of each element. But there is too much code. Is there any clever way to to this?

Answer 1

You can try with below css and see if it works.

.main_content {
  width: 100%;
  height: 400px;
  font-weight: 800;
}

.main_content>* {
  border: 1px solid red;
  display: table;
  margin: 0 auto;
  margin-bottom: 30px;
  text-align: center;
}

<div class="first_article">
  <div class="first_content">
    <div class="main_content">
      <span class="growth">Growth</span>
      <h2>5 compelling user referral campaign examples</h2>

Answer 2

Just 1 CSS function: width: fit-content Note here: It doesnt work in IE. Try it out:

.main_content {
   width: 100%;
  height: 400px;
  font-weight: 800;

}

.main_content > * {
  border: 1px solid red;
  display: block;
  margin-bottom: 30px;
  text-align: center; 
  width: -moz-fit-content;
  width: fit-content;
}

<div class="first_article">
  <div class="first_content">
    <div class="main_content">
       <span class="growth">Growth</span>
