Can you tell me what is creating the space between the elements in this form?

For an example, take a look at this link:

I am puzzled by the gap between the form-group and the button, as well as between the different form-groups. When using Bootstrap 4 with flexbox activated, all my elements (inputs and buttons) collapse without any margin in between them.

How can I identify what is causing the highlighted form-group to separate from the adjacent button? I have not been able to pinpoint the issue using the Chrome inspector.

Thank you.

Answer №1

Understanding why two DIVS behave a certain way can be quite complex, but it ultimately comes down to their display property being set as display:inline-block. This causes them to act like words in a sentence within an inline formatting context. The presence of spaces in the HTML code is crucial for rendering proper spacing between elements. When inspecting the elements in Chrome Inspector, the formatting may obscure this fact. However, manipulating the HTML within Chrome Inspector can reveal how spaces affect the layout.

To see a demonstration of this concept, you can visit this CodePen example: http://codepen.io/MarkAtRamp51/pen/XKYNpZ

A comparison between two snippets of HTML code highlights the impact of whitespace on layout:

First, the snippet displaying whitespaces between form groups:

<input type="text" class="form-control" id="exampleInputName2"
placeholder="Jane Doe">   </div>   
<div class="form-group">
     <label for="exampleInputEmail2">Email</label>

And next, the snippet with no whitespaces between form groups:

<input type="text" class="form-control" id="exampleInputName2" placeholder="Jane Doe">
  </div><div class="form-group">
    <label for="exampleInputEmail2">Email</label>

The difference is evident when comparing the two examples where the second set of DIVs are positioned adjacent to each other.
