— that is, on the user interface screen — to develop applications that adapt to any device.

In WordPress , for example, it can be installed as a theme or used for plugin development or even within plugins to stylize their functions. The purpose of the framework is to offer the user a more pleasant experience when browsing a site.

For this reason, it has several resources to configure the styles of page elements in a simple and efficient way, in addition to facilitating the construction of pages that are, at the same time, adapted for the web and for mobile devices .

The above demonstrates why it is important to  spain phone number data know a potential structure of this type.

With that in mind, we put together this complete beginner’s guide. Read on!

What is Bootstrap?

Bootstrap is a CSS framework developed by Twitter in 2010, to standardize the company’s tools.

Initially it was called Twitter Blueprint, and a little later in 2011 it was open sourced and renamed Bootstrap. Since then it has been updated several times and is now at version 4.4.

The framework combines CSS and JavaScript to style the elements of an HTML page. It allows for much more than just changing the color of buttons and links.

This is a tool that provides interactivity on the page, so it offers a series of components that facilitate communication with the user, such as navigation menus, page controls, progress bars and more.

In addition to all the features that the framework offers, its main objective is to allow the construction of responsive websites for mobile devices .

This means that the pages are designed to work on desktop, tablets and smartphones, in a very simple and organized way.

How does Bootstrap work?

Bootstrap is made up of a series of CSS and JavaScript files responsible for assigning specific characteristics to page elements.

There is a main file called bootstrap.css, which contains a definition for all the styles used. Basically, the framework structure consists of two directories:

• css: contains the files needed for styling elements and an alternative to the original theme;
• js: Contains the backend of the bootstrap.js file (original and minified), responsible for running styled applications that require interactive manipulation.

To assign a characteristic to an element, w mary hartje president e simply need to inform the corresponding class in the “class” property of the element that will be styled, as shown in the following example:

In this example, the content “rounded-sm” was assigned to an image property. It is a style that adds rounded edges, not an element.

Therefore, when the image is loaded, the characteristics that refer to this class will be applied to the element.

What is the functionality of Bootstrap?

Bootstrap offers a number of features that can be implemented on a website. Below we will discuss the possibilities of this tool.

Responsive design

One of the main features of Bootstrap is to uk cell number  allow the adaptation of the page to be done according to the type of device used. To ensure responsiveness, the framework works with:

• styling the <div> element;
• the use of the container class.

In practice, the <div> element works to create a series of notes, similar to a table, capable of structuring the page in an adaptable way.

There was an attempt to use tables to create responsive layouts, however there were limitations in defining the length of columns which made it impossible to use them on smaller devices, such as smartphones.

The <div> element is more flexible, allowing you to easily define and resize the length.

Bootstrap has assigned the <div> element a container class property, which works to determine the appropriate dimensions for elements inserted into that space.

Basically, the framework works with three types of containers:

• Container: As a set with a maximum width property, which determines what canvas size is ideal for creating the page layout.
• Container-fluid: Considers the total length of the device fabric to define the layout. For this, the width property —100% at all fabric size limits— is considered.
• Container-{ breakpoint}: considers width —100% until reaching a certain size—.

Component Library

Another interesting feature of this framework is the number of components that can be used
