When you talk about responsive web design, it means building a webpage that alters how it looks by use of CSS3 media queries. This means that a single HTML code is used irrespective of the gadget accessing it, with the presentation changing using CSS3 media queries, specifying the rules that will apply to the browser that’s displaying the webpage. With responsive web design, the server will always send a similar HTML code towards all devices with CSS being used to alter how the page is rendered on the gadget.
BENEFITS OF RESPONSIVE DESIGN
Responsive design relies on Cascading Style Sheets (CSS), which govern fonts, colors, layouts and spacing. CSS make your content more attractive and ensures consistent styling throughout your site. It also saves time, because you only need to make a fix once for it to reflect on every page.
