Align text and input so that they are neatly inline vertically - html

Question

A bit of a beginner's question, I am trying to make my form to look like the following image where the text on the left are vertically aligned and the input field has the same widths.
twitter form
<div class="container">
<div class="row">
<div class="col-md-6">
<label class="d-inline">Full Name: </label>
<input type="text" placeholder="First Name" formControlName="firstName">
</div>
<div class="col-md-6">
<h6>Some text</h6>
</div>
</div>
<br>
<div class="row">
<div class="col-md-6">
<label class="d-inline">Email: </label>
<input type="email" placeholder="Email" formControlName="email">
</div>
<div class="col-md-6">
<h6>Some text</h6>
</div>
</div>
</div>
Which gives me the following result. I also want the input to stretch to the remaining parent container so that it stops before the "some text".
my attempt
I have tried to set the width css property of the input field to 100% hoping that it will do it. However, that just stretch it all the way which forces it to go to the next line.
I am using bootstrap 4 with Angular2.

Answer 1

Just give your p tag a min-width. I gave the input a max-width so it's better when your screen size is smaller. Hope this answers your question
p.d-inline {
min-width: 75px;
display: inline-block;
text-align: right;
margin-left: 30px;
}
h6 {
margin-left: 30px;
}
input {
max-width: 100px;
}

You said you are using Bootstrap.
Why not Use Bootstrap Form then?

Open the following snippet in Full Page to see how it works
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<form class="form-horizontal">
<div class="form-group">
<label for="inputEmail3" class="col-lg-1 control-label">Email</label>
<div class="col-lg-2">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-lg-1 control-label">Password</label>
<div class="col-lg-2">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-lg-offset-1 col-lg-2">
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-lg-offset-1 col-lg-3">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</form>

As form-horizontal is not working as expected in bootstrap 4 so, you can try like this.
<div class="container">
<div class="row">
<div class="col-md-6 form-group row">
<label class="d-inline control-label col-md-3 text-right">Full Name: </label>
<div class="col-md-9">
<input class="form-control" type="text" placeholder="First Name" formControlName="firstName">
</div>
</div>
<div class="col-md-6">
<h6>Some text</h6>
</div>
</div>
<br>
<div class="row">
<div class="col-md-6 form-group row">
<label class="d-inline control-label col-md-3 text-right">Email: </label>
<div class="col-md-9">
<input class="form-control" type="email" placeholder="Email" formControlName="email">
</div>
</div>
<div class="col-md-6">
<h6>Some text</h6>
</div>
</div>
</div>
