Bootstrap: Play With Grid System (Part One)

According to Bootstrap, grid systems are used for creating page layouts through a series of rows and columns that house your content. Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases.

There are four main grid sizes:

Extra Small devices (col-xs-): phone
Small devices (col-sm-): tablet
Medium devices (col-md-): desktops
Large devices (col-lg-): desktops

The instructor shows us how to build a responsive grid system.

After we link the bootstrap css file, we are going to create the grid system on the body part. Since grid systems only scale up to 12 columns, we can create layouts in different units.

In the HTML, we create a "container" first, so the grid system will be inside the container.

Then we create a class attribute value equal "row" in the div tag, so all units will stay in one row just like the table data stay in the table row. And each row scales 12 columns (units).

In the first row, we create three cells. The first cell and the last cell have the same size and units which are "col-lg-2". It means that each cell is large size and scales two columns. The middle cell is also large size but scales 8 columns. The sum of these three cell columns is 12.

For the second row, we create three same size and unit cells. They are all large size, and each will take four units.

In order to compare these two rows, I assign them in different colors in the CSS. The first row is pink, and the second row is orange.

The result:

Intermediate Express.js: How To Add Styles & Partials in EJS File?

So far, we only have simple HTML tags and ejs tags in each ejs file. Every template page has no style at all. And the basic HTML header and footer are also missing.

Seven Most Common jQuery Methods Last Part: ADD/REMOVE/TOGGLE CLASS()

My Story: A Mommy Start To Learn Code From Zero

From Google Image I am not a programmer, and I thought I would never become one. Everytime I see someone is coding, I think he or she must be very talent. For me, coding is a very difficult subject to learn. Not only the language has so many rules, but also the logical reasoning behind the language is complex. In my graduated school, I knew many friends who didn't have any coding background, but they are doing programmer or developer jobs now. Some of them went to school to study coding, and some of them learned to code by themselves. Their stories are so impressive. I wasn't ready to learn code until I finished my first Chinese book "留学，我的青春呀!" recently. I always want to be a writer and write my own book. I started writing blog three years ago, and I updated my post two to three times every week. As I enjoyed writing , I started to get some followers, likes, and good comments on my blog. Then, I decided to plan my first book. My First...
