Why should every developer be concerned about making a website responsive? Well, It solves your website's problems and makes your website mobile friendly and improves user experience across all devices. It also reduces website bounce rate and increases the amount of time that visitors spend on the website.
Fluid grids, flexible images, and media queries are the three technical ingredients to make a website responsive.
But it’s not that easy to build a website completely responsive. Developers face many difficulties in achieving this. Sure, there are frameworks and tools to make responsive design easier but it’s not going to open in one night. It is still going to require your significant work.
When I mentioned tools I want to mention what are they,
Blisk, Sizzy, Responsively App, Polypane, etc..,
Polypane is the main reason why I’m writing this post. Yes, It’s absolutely the best tool to make a website responsive, compatible and accessible across all devices & browsers. I also want to mention that Polypane is on a lifetime deal at SaaS Mantra for just $69. You can pay for one time and use the tool as long as you need. And I’m not sure if any deals are running on other tools I mentioned above. If you know about it mention it in the comment section.
P.S Here's the link for Polypane deal, https://saasmantra.com/deals/polypane
