As of 2013, there were over 1.2 billion people accessing the Web from their mobile devices, with mobile traffic accounting for 15% of all Internet traffic. More than ever before, people are accessing content on mobile devices. With it now being possible to access the Web on a multitude of different devices of all shapes and sizes, it has become more important than ever to make sure that the presentation of web pages is optimized based on the device they’re being viewed on. Part 1: Responsive Web design and mobile optimization with HTML5, CSS3, and Bootstrap
Now it’s time to take a step back and focusing on how the implementation of its design can have a profound impact on its overall usability. In the previous lessons, we’ve been focused mainly on the functionality of our New Year’s Resolution list. This is lesson 5 of the Mini Web App course, which walks you through the creation of a simple web application, covering HTML and CSS, PHP, Bootstrap, Local Storage, and more. Inside the wider column, add the following code: Title įor more details, head over to Bootstrap’s Grid docs, which are really user-friendly and packed with awesome information.Responsive Web Design With HTML5, CSS3, and the Bootstrap Frameworkīy Alex Coleman | Mini Web App, Web App, Web Development Our demo is going to have three equal-length, nested columns. You can’t have more than 12 columns overall, but you can certainly have fewer than 12 if you like. This particular one is part of the spacing utility classes and is used to create some margin at the bottom of each column.īootstrap lets you easily nest columns by adding a further div element with the class of row inside the containing column. The mb-4 class is one of the many utility classes Bootstrap makes available. Their sum amounts to 12, which is the total number of columns in the Bootstrap grid: 8 + 4 = 12. Also, notice the numbers at the end of the col-md-* class. Smaller screens will get both columns stacked on top of each other. The col-md-* class indicates that the two-column layout will only be triggered from medium-sized screens upwards. We start by sectioning out the page into two columns, a wider and a smaller column. data-target is used to identify which menus to hide/show.įor the content section, we’ll be using the new Flexbox-based Bootstrap grid system. Also see we’ve used data-toggle=collapse that Bootstrap uses to hide/show the menu items in smaller windows. This link is visible only on the smaller screens with a list icon. Just below the branding, you might be seeing an additional link with the navbar-toggler class that wraps a span navbar-toggler-icon. The nav items are wrapped inside an additional div with the classes collapse navbar-collapse, which are used to make the menu appear like a stack when viewing in smaller browsers. It should be clear that adding the class navbar-brand gives the title a clean look and is used for the website’s name. The branding and menu items are self-explanatory. Let’s see the real magical stuff that makes the navigation responsive. Till now, whatever we’ve added is just the basic structure of our navigation bar. The container is used to contain everything inside the navigation bar as a wrapper.

Let’s move ahead and insert some more code into it:
The navbar-light and bg-light classes control the text color and background color of the navigation bar respectively. An additional fixed-top class makes it stick to the top of the page. The navbar class is for showing the navigation section. This is going to be fixed to the top of the website, as you’ve seen in the demo page. It will contain the website’s title and some right-aligned menu link items. Let’s build the navigation bar of the website.
