How they Achieved Responsiveness ?
• Using Media Queries in CSS3
• @media rule allows website to have a different layout for screen, mobile phone, tablet, etc.
• A @media query generally consists of a media type and at least one expression that limits
the style sheet's scope by using media features, such as width, height, and colour.

<link rel="stylesheet" media="(max-width: 800px)" href="example.css" />

<style>
@media (max-width: 600px) {
.facet_sidebar {
display: none;
}
}
@media (min-width: 700px) and (orientation: landscape) { ... }
</style>

Getting Started

Take the latest version of IE, and don’t make us cry.
Render the content acc. to physical width of device.
At first load no zoom. Enable zooming using “user-
scalable” , “maximum-scale”.

Grid System

2. Small devices - Tablets (≥768px) - .col-sm-[num]
3. Medium devices - Desktops (≥992px) - .col-md-[num]
4. Large devices - Desktops (≥1200px)- .col-lg-[num]
