How to Enable Bootstrap 3 Hover Dropdowns

I love Bootstrap, but I’m not really a fan of the navigation it creates. It works really well when you’re prototyping, but if you’re doing a high-level design project, you’re better off going custom. Bootstap’s default navigation doesn’t have out-of-the-box hover dropdowns, and the mobile menu is arguably pretty boring. If you do use it though, there are some tricks to help you tweak it without going completely custom.
Some clients, sites, or apps will require you to have hover dropdowns on desktop. As you can see below, this doesn’t come out-of-the-box with Bootstrap 3.

Defining Proper Media Queries

Bootstrap has clearly defined breakpoints for different kinds of devices, specified by using CSS media queries. The following are the breakpoint categories used for the different types of devices:
  1. Extra Small Devices (e.g. cell phones) are the default, creating the “mobile first” concept in Bootstrap. This covers devices smaller than 768px wide.
  2. “Small Devices” (e.g. tablets) are targeted with @media (min-width: 768px) and (max-width: 991px) { ... }.
  3. Medium Sized Devices (e.g. Desktops) have a screen size smaller than 1200px and greater than 991px, using @media (min-width: 992px) and (max-width: 1199px) { ... }.
  4. Larger Devices (e.g. wide-screen monitors) are greater than 1200px, targeted using @media (min-width: 1200px) { ... }.

Who Creates CSS?

CSS is created and maintained through a group of people within the W3C called the CSS Working Group. The CSS Working Group creates documents called specifications. When a specification has been discussed and officially ratified by W3C members, it becomes a recommendation.
CSS Syntax
A CSS comprises of style rules that are interpreted by the browser and then applied to the corresponding elements in your document. It consists of 3 parts
  • Selector 
  • Property 
  • Value
1) What is the difference between HTML and HTML5 ?

2) What is the <!DOCTYPE> ? Is it necessary to use in HTML5 ?
Ans:  The <!DOCTYPE> is an instruction to the web browser about what version of HTML the page is written in. AND The <!DOCTYPE> tag does not have an end tag and It is not case sensitive.
The <!DOCTYPE> declaration must be the very first thing in HTML5 document, before the <html> tag. As In HTML 4.01, all <! DOCTYPE > declarations require a reference to a Document Type Definition (DTD), because HTML 4.01 was based on Standard Generalized Markup Language (SGML). WHERE AS HTML5 is not based on SGML, and therefore does not require a reference to a Document Type Definition (DTD).
