Bootstrap 4 - Texto
Descrição
O Bootstrap fornece utilitários de texto para controlar o alinhamento, transformação, peso do texto e muito mais.
Alinhamento de Texto
O texto pode ser justificado usando a classe .text-justify e para o alinhamento à esquerda, à direita e ao centro do texto, use as classes text-left , text-right e text-center , respectivamente.
O exemplo a seguir demonstra o uso de utilitários de alinhamento de texto -
Exemplo
<html lang = "en">
<head>
<!-- Meta tags -->
<meta charset = "utf-8">
<meta name = "viewport" content = "width = device-width, initial-scale = 1, shrink-to-fit = no">
<!-- Bootstrap CSS -->
<link rel = "stylesheet"
href = "https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
<title>Bootstrap 4 Example</title>
<style type = "text/css"></style>
</head>
<body>
<div class = "container">
<h2>Text alignment: Text Justify </h2>
<p class = "text-success">
The below text is justified by using the class "text-justify"
</p>
<p class = "text-justify">
Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum has been the industry's standard dummy text ever since the
1500s, when an unknown printer took a galley of type and scrambled it to
make a type specimen book. It has survived not only five centuries, but
also the leap into electronic typesetting, remaining essentially unchanged.
It was popularised in the 1960s with the release of Letraset sheets
containing Lorem Ipsum passages, and more recently with desktop publishing
software like Aldus PageMaker including versions of Lorem Ipsum.

<h2>Text alignment: Left, Right, Center </h2>
<p class = "text-left">Text is aligned on Left side by using class "text-left"</p>
<p class = "text-center">Text is aligned at Center by using class "text-center"</p>
<p class = "text-right">Text is aligned on Right side by using class "text-right"</p>

Transformação de Texto
Você pode transformar o texto usando classes de letras maiúsculas, conforme mostrado no exemplo a seguir -
Exemplo
<html lang = "en">
<head>
<!-- Meta tags -->
<meta charset = "utf-8">
<meta name = "viewport" content = "width = device-width, initial-scale = 1, shrink-to-fit = no">
<!-- Bootstrap CSS -->

<style type = "text/css"></style>
</head>
<body>
<div class = "container">
<h2>Text Transform</h2>
<p>Welcome to
<span class = "text-lowercase">tutorialspoint (text-lowercase)</span>.
</p>
<p>Welcome to
<span class = "text-uppercase">tutorialspoint (text-uppercase)</span>

Peso da fonte, itálico e monoespaço
Você pode alterar a espessura da fonte do texto usando a classe font-weight- * e colocar o texto em itálico usando a classe font-italic . A fonte monoespaçada cria texto de largura fixa, que ocupa a mesma quantidade de espaço horizontal.
O exemplo a seguir demonstra o uso dos utilitários acima -
