  align-items: center;
  width: 100%;
  margin: 10px 0;
}

.line {
  width: 100%;
  height: 1px;
  background-color: red;
}

.the-dot {
  width: 1px;
  height: 1px;
  background-color: red;
  border-radius: 999px;
}

.children input {
  border: none;
  border-bottom: 1px solid;
  margin-right: 5px;
  flex-grow: 1;
}

<div class="parent">
  <div class="children">
    <input type="text" placeholder="Type something...">
    <div class="line"></div>
    <div class="the-dot"></div>
  </div>
</div>

Answer 1

Without using flex and nesting the dot inside the line I ended up to this:

.parent {
  max-width: 352px;
  width: 100%;
}


.line{
  width: 100%;
  height: 1px;
  background-color: black;
  margin-top:15px;
  display:block;
}

.the-dot {
  width: 8px;
  height: 8px;
  background-color: red;
  border-radius: 50%;
  display:inline-block;
  float:right;
  margin-top:-4px;
  }

input {
  width:100%;
  display:block;
  border: none;
  border-bottom: 1px solid;
  outline:0;
  border:0;
}

<div class="parent">
    <input type="text" placeholder="Type something...">
    <div class="line"><div class="the-dot"></div></div>
</div>
