I want to style an input by adding an dot at the end of it. Same As The Image Below

I’ve Tried To add some styling for :before :after but i couldn’t figure it out

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

.children {
  display: flex;
  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>

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: 10px;
  height: 10px;
  background-color: red;
  border-radius: 50%;
  display:inline-block;
  float:right;
  margin-top:-5px;
  }

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>

Simply use position: absolute to position a dot created using border-radius and aspect-ratio:

.children {
  position: relative;
}

.the-dot {
  position: absolute;
  /* 100% of .children's height, minus half its size, minus half line width. */
  top: calc(100% - var(--size) / 2 - var(--border) / 2);
  /* 100% of .children's width, minus half its size. */
  left: calc(100% - var(--size) / 2);
  /* Make it round */
  border-radius: 50%;
  height: var(--size);
  /* Ensure that its height is equal to its width */
  aspect-ratio: 1 / 1;
}

Alternatively, you can use a pseudo-element:

.children::after {
  content: '';
  /* idem */
}

Try it:

/* Play with these */
:root {
  --size: 5px;
  --color: #f00;
  --border: 1px;
}

.children {
  position: relative;
}

.the-dot {
  position: absolute;
  top: calc(100% - var(--size) / 2 - var(--border) / 2);
  left: calc(100% - var(--size) / 2);
  border-radius: 50%;
  height: var(--size);
  aspect-ratio: 1 / 1;
  background: var(--color);
}


/* Demo only */

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

.children {
  display: flex;
  align-items: center;
  width: 100%;
  margin: 10px 0;
}

.children input {
  border: none;
  border-bottom: var(--border) solid;
  flex-grow: 1;
}

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