How to make .input-area container take the exact same amount of space that its childs take?

@TemaniAfif yes, thank you. I've already found out this. And it's supported in more browsers than width: fit-content — Coder4Fun, Jul 08 '21 at 21:33

Apply width:fit-content:

.form {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-orient: vertical;
  -webkit-box-direction: normal;
  -ms-flex-direction: column;
  flex-direction: column;
  font-family: Arial, Helvetica, sans-serif!important;
  margin: 0 auto;
  width: 650px;
  min-height: 200px;
  background: var(--first-color);
  color: #000;
  padding: 5%;
  border: thin solid #ccc;
}

.form__header {
  margin: 0 auto;
  color: var(--third-color);
  font-size: 20px;
  margin-bottom: 15px;
  font-weight: bold;
  text-align: center;
}

.form-input-wrap {
  width: 60%;
}

.input-area {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  padding-bottom: 5px;
  margin-bottom: 15px;
  border-bottom: thin solid #ccc;
  width: fit-content;
}

.input-area label {
  width: 150px;
  font-size: 20px;
  color: var(--third-color);
}

.input-area input {
  border: thin solid #ccc;
  height: 22px;
}

.input-area input:focus {
  outline: none!important;
}

.text-input {
  resize: none;
  width: 90%;
  min-height: 100px;
}

.text-input:focus {
  outline: none;
}

.form input[type="submit"] {
  width: auto;
  margin: 0 auto;
  background: var(--third-color);
  color: #fff;
  border: none;
  border-radius: 15px;
  padding: 5px;
  margin-top: 15px;
}

.form input[type="submit"]:hover {
  background: darkred;
  cursor: pointer;
}

<form action="" class="form">
  <div class="form-input-wrap">
    <div class="form__header">Leave a review</div>
    <div class="input-area">
      <label>Name</label>
      <input type="text" name="name">
    </div>
    <textarea class="text-input"></textarea>
  </div>
  <input type="submit" value="Publish">
</form>

for firefox, max-content works , fit-content seems not. – G-Cyrillus Jul 08 '21 at 21:05 — G-Cyrillus, Jul 08 '21 at 21:05

to include Firefox, i would use max-contentinstead fit-content in place width:auto;that you have set for .input-area.

.form {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-orient: vertical;
  -webkit-box-direction: normal;
  -ms-flex-direction: column;
  flex-direction: column;
  font-family: Arial, Helvetica, sans-serif!important;
  margin: 0 auto;
  width: 650px;
  min-height: 200px;
  background: var(--first-color);
  color: #000;
  padding: 5%;
  border: thin solid #ccc;
}

.form__header {
  margin: 0 auto;
  color: var(--third-color);
  font-size: 20px;
  margin-bottom: 15px;
  font-weight: bold;
  text-align: center;
}

.form-input-wrap {
  width: 60%;
}

.input-area {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  padding-bottom: 5px;
  margin-bottom: 15px;
  border-bottom: thin solid #ccc;
  width:max-content;
}

.input-area label {
  width: 150px;
  font-size: 20px;
  color: var(--third-color);
}

.input-area input {
  border: thin solid #ccc;
  height: 22px;
}

.input-area input:focus {
  outline: none!important;
}

.text-input {
  resize: none;
  width: 90%;
  min-height: 100px;
}

.text-input:focus {
  outline: none;
}

.form input[type="submit"] {
  width: auto;
  margin: 0 auto;
  background: var(--third-color);
  color: #fff;
  border: none;
  border-radius: 15px;
  padding: 5px;
  margin-top: 15px;
}

.form input[type="submit"]:hover {
  background: darkred;
  cursor: pointer;
}

<form action="" class="form">
  <div class="form-input-wrap">
    <div class="form__header">Leave a review</div>
    <div class="input-area">
      <label>Name</label>
      <input type="text" name="name">
    </div>
    <textarea class="text-input"></textarea>
  </div>
  <input type="submit" value="Publish">
</form>
