Your structure and class names are a little bit off. You need a span.input-group-text nested inside a div.input-group-prepend
<div class="form-group">
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text">$</span>

<input type="number" class="form-control" id="amount" placeholder="Loan Amount">

.input-group-addon does not appear in the v4.0 documentation that was for v3.

The favicon works so the image source is valid. I wrote a little css to size up the image and position it to the top left:
This is what shows up on the page after refreshing cache:
<div class="logo" src="icons/test-image.png" alt="rnl-logo"></div>
You can't use an image directly without using img tag.
The correct way should be :
<div class="logo">
<img class="" src="./icons/test-image.png" alt="rnl-logo">
</div>
OR:
<img class="logo" src="./icons/test-image.png" alt="rnl-logo">

Align the form to the center in Bootstrap 4 [duplicate]
(3 answers)
Closed 2 years ago.
I'm trying to put a text field in the center of me screen, yet everything I try, it just stays left align. How do I center this?
<div class="form-row">
<div class="col-md-4 col-md-offset-4">
<div class="form-group">
<label asp-for="FirstName"></label>:
<input asp-for="FirstName" class="form-control" />
</div>
</div>
</div>
Solution 1) You can use class= "offset-md-4" in bootstrap-4. It's not col-md-offset-4
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
<div class="form-row">
<div class="col-md-4 offset-md-4">
<div class="form-group">
<label asp-for="FirstName"></label>:
<input asp-for="FirstName" class="form-control" />
</div>
</div>
</div>
Solution 2) You can use class="mx-auto" which is nothing but margin-left:auto
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
<div class="form-row">
<div class="col-md-4 mx-auto">
<div class="form-group">
<label asp-for="FirstName"></label>:
<input asp-for="FirstName" class="form-control" />
</div>
</div>
</div>
You are using bootstrap so just simply put text-center class on input like this.
<div class="form-row">
<div class="col-md-4 col-md-offset-4">
<div class="form-group">
<label asp-for="FirstName"></label>:
<input asp-for="FirstName" class="form-control text-center" />
</div>
</div>
i tried your cod ants all center after putting the class.
<!DOCTYPE html>

</div>
</div>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</body>
</html>
<div class="col-md-4 col-md-offset-4">Put your form here</div>
col-md-4 will take 4 columns out of 12.
col-md--offset-4 will add one 4 column to both sides of this form.
You needed to show your custom css. Perhaps there are rules that may override the rules suggested here.
Try like this:
div.form-row div.col-md-4.col-md-offset-4 div.form-group {
display: flex!important;
justify-content: center!important;
}
<div class="form-row">
<div class="col-md-4 col-md-offset-4">
<div class="form-group">
<label asp-for="FirstName"></label>:
<input asp-for="FirstName" class="form-control" />
</div>
</div>
</div>
I'm trying to force a search box to take up the entire width of the container, but I can only ever get it to take up roughly half the width. Here is some representative code:
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="input-group">
<input id="submitted_word" type="text" class="flex-fill mr-2 form-control" placeholder="Enter Words Here">
<div class="input-group-append">
<button id="submit_button" class="btn btn-primary" type="button">Submit Word</button>
</div>
</div>
</div>
</div>
And a link to JSFiddle: http://jsfiddle.net/ovLab58u/
I've followed every one of the answers listed here, and nothing seems to be working: Bootstrap 4 inline form full width
Just add display: block style to the div having class input-group either as inline style or as external css class
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.2/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="input-group" style="display: block;">
<input id="submitted_word" type="text" class="flex-fill mr-2 form-control" placeholder="Enter Words Here">
<div class="input-group-append">
<button id="submit_button" class="btn btn-primary" type="button">Submit Word</button>
</div>
</div>
</div>
</div>
I just add bootstrap v4.4 CDNs from https://getbootstrap.com/docs/4.4/getting-started/introduction/ to your code and also add a "div closed tag" that you did not closed in your code. and it works correctly. like the code below

If I do not set my HTML and BODY tag class = "h-100" They are showing at like 210 pixels. I then have to keep setting lower level elements to h-100 also.
I'm really not sure how to fix it other than adding the h-100
<html class="h-100" lang="en">

<body class="h-100">
I believe that the correct result of bootstrap HTML and body is that it should size it self roughly to the size of the viewing medium.
Here is the full page of what I'm trying to accomplish on jsfiddle.
https://jsfiddle.net/v2cqh3n8/
The reason I am trying to have the body set to a nice size is because I want to center align the login form. Which I am also having trouble with.
Try this bootstrap solution. Hope it works better for you, without adding height to BODY and HTML Tag .
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<div class="container h-100">
<div class="row align-items-center h-100">
<div class="col-6 mx-auto">
<div class="form-group">
<label for="">Username</label>
<input type="text" class="form-control">
</div>
<div class="form-group">
<label for="">Password</label>
<input type="text" class="form-control">
</div>
<button class="btn btn-primary">Log-in</button>
</div>
</div>
</div>
It worked by simply adding height to body in vh unit. h-100 justify-content-center to .row
Here is working example:
https://jsfiddle.net/HarishBoke/faocwnp6/1/
If all you want to do is put the form in the centre of the page, just use flexbox.
I've added in you js fiddle with the correct bootstrap classes.
The reason you need to set h-100 on these elements is that the content within those elements is not filling the DOM.
Side-note: You also don't need all of the containers/rows if you're just centering the element.

Just set the height of the html and body to 100% using css or h-100 classes and then add d-flex and align-items-center classes to the body.

body {
height: 100%;

The code above does contains the body part but it is not showing in the debugger console. I tried remove caching, installing different browsers, but all in vain.
I am trying to learn flask and that is why the url path is specified differently.
You are missing a </script> tag in your header this will fix the problem you are having.
