Several years back, I created my web based CV. It was an awesome website and I was very proud of it. Below are a few screen shots. I was very proud of this and told the first person I met to check it out. He whipped out his phone and went to the URL - https://bharath.lohray.com/cv. The page I saw was a huge disappointment!

While the CV website looked fantastic on a desktop, they did poorly on a mobile device.

I had not given a single thought to how the site would look on a mobile device. After all the efforts I had put to get it to work, I had no heart to tweak (rewrite from scratch) the page any further. Now, several years later, I decided to rewrite my online CV this time with the "Mobile First" philosophy in mind. Over the years I discovered that using a pre-built CSS framework was the most predictive way to build a page that would works across all device sizes. I took a special liking to Bootstrap CSS. After a few projects on Bootstrap, I discovered that I was using Bootstrap CSS, jQuery, Bootstrap JS and jQuery UI and add jQuery Mobile to the mix if it were a mobile website.

In spite of all the libraries bloating my page, I still did not get every thing I wanted. I was hesitant to modify any of Bootstrap CSS files as this would be a major hurdle to upgrading Bootstrap with newer versions. So, I decided to take the best of Bootstrap CSS and make it my own. And the best of Bootstrap CSS is it's responsiveness!

/* print */
@media print {
}

/* xs */
@media (max-width: 767px) {
}

/* sm+ */
@media (min-width: 768px) {
}

/* md+ */
@media (min-width: 992px) {
}

/* lg */
@media (min-width: 1200px) {
}

/* sm */
@media (min-width: 768px) and (max-width: 991px) {
}

/* md */
@media (min-width: 992px) and (max-width: 1199px) {
}

/* some deprecated IE stuff - don't worry about it! */
@-ms-viewport {
}

Here is the gist containing the code.

This CSS skeleton extracted from bootstrap.css lets me fill in my styles across the various screen sizes and bring responsiveness to my pages with the greatest ease. Here are the results of my 3-2-1 fall back multi-column CSS - very impressive!
