I am having something like this:
How do I expand the width that the border it will also cover the icon on the left like this:
My HTML:
.input-group-text {
  width: 48px;
  border-right: none;
  background-color: #ffffff;
}
[class^="fa-"], [class*=" fa-"] {
  display: inline-block;
  width: 100%;
}
.LoginInput {
  border-left: none;
  position: relative;
}<b-input-group>
  <b-input-group-prepend>
    <span class="input-group-text"><i class="fa fa-user fa-lg"></i></span>
  </b-input-group-prepend>
  <b-form-input class="LoginInput" size="lg" placeholder="Username">
  </b-form-input>
</b-input-group>
<b-input-group>
  <b-input-group-prepend>
    <span class="input-group-text"><i class="fa fa-lock fa-lg"></i></span>
  </b-input-group-prepend>
    <b-form-input class="LoginInput" size="lg" type="password" placeholder="Password">
    </b-form-input>
</b-input-group>
