Bootstrap is a highly responsive framework for front-end web development. The implementation of HTML, CSS, and JS is greatly instrumental in building web applications, (especially mobile-based web apps) with great efficiency. It is a sleek, intuitive, and open-source framework used popularly among developers.
Containers are fundamental building blocks of the Bootstrap framework. It constitutes one of the most basic forms to format the layout of the page. Containers are mostly used to contain, pad and center align content. They can be nested if required. There are three different types of containers.
The first code to be used is the <code> tag. If code is to be displayed inline, the code is to be used as the <code> tag.
Second is the <pre> tag. If the code has to be displayed as a standalone block element or if it has multiple lines, then the code to be used is the <pre> tag.
<p>To display code as a standalone block element use &tl;pre> tag as:</p>
<pre>
&tl;article&tg;
&tl;h1>Article Heading&tl;/h1&tg;
&tl;/article&tg;
</pre>

Bootstrap has an edge in terms of extending mobile support for applications.
The grid system of Bootstrap is not only fluid-based but associated with fixed patterns as well.
In comparison to Foundation, it offers a vast variety of UI elements. Aided by the use of pixels, Bootstrap offers to design for desktop and mobile (both).
Lists are one of the core styling elements using Bootstrap. List group classes are coupled with contextual classes to render different colors. The most applied ones are primary, secondary, info, success, danger, warning, light, and dark. To create a list, Bootstrap element ul (<ul>) has to be modified.
Navbar is a navigation header for Bootstrap websites. It is a prominent feature that is the very responsive meta component. In the mobile version, it collapses to three horizontal bars.
To create a basic default navbar:
To <nav> tag, add the classes .navbar and .navbar-default.
Assign “navigation” to the role to the above tag, for ease of accessibility.
To the <div> element, add the header class .navbar-header. Adding an <a> element with class navbar-brand will render larger text size.
To further enhance responsiveness, wrap the matter to be collapsed in <div> by classes .navbar-collapse and .collapse.
Icon fonts used in web projects are called glyphicons. Legitimate licensing is required to implement these. However, some glyphicons are free for use. For the Bootstrap 3 version, glyphicons are available in their downloaded directory within the fonts folder.
Code to execute glyphicons:
<span class = "glyphicon glyphicon-search"></span>

First, add a basic alert by creating a wrapper class <div> and then add a class of .alert along with any of the four contextual classes. Then add optional .alert-dismissable to the above created <div> class. To conclude the operation add a close button at the end. Lastly use the <button> element and assign data-dismiss = “alert” attribute.
