Introduction
Mobile web development is the process of creating a website that can be accessed by devices such as smartphones, tablets, and other mobile devices. This involves developing a site’s content, functionality, and design using HTML5.
What you will learn in this guide: The different types of mobile websites (responsive), how they work and what they look like; Writing CSS code for responsive sites; Handling multiple screen sizes on one page; Using JavaScript libraries to enhance your app’s functionality or add new features like social sharing buttons or payment forms
Mobile First
Mobile first is a web design approach that means designing for mobile devices first, then scaling up to desktop and tablet versions. It’s a strategy for ensuring that your website works well on all devices.
Mobile users tend to be more impatient than desktop users, which means they will scroll past ads or content unless it’s displayed in an appropriate way—and this may not be possible if the content isn’t easily readable on their screens (especially if they’re viewing it from an angle). By designing your site specifically with mobile users in mind, you’ll make sure that every page looks as good as possible no matter where someone is viewing it from.
Responsive Web Design
Responsive Web Design is the process of designing your website so that it looks good on any device. It can be used to create a single website, or it can be used to design multiple different versions of your site, depending on the needs of each individual user.
While there are benefits and drawbacks to responsive web design, it’s important for you to understand what they are before deciding if this is right for your business or not.
CSS Media Queries
Media queries are a powerful tool for enhancing the user experience of your website. They allow you to create more flexible and dynamic layouts, which can help you create beautiful and functional websites.
Media queries are used in conjunction with CSS media types (e.g., screen, print) to determine how CSS should be rendered when the device size or orientation changes between devices with different pixel densities or resolutions. You can use media queries in order to fine-tune your design based on these factors:
Screen size: Use this if you want different styles depending on whether a visitor is using an iPhone 6 or Android phone with a 480×320 pixels display resolution
Orientation: This is useful when designing interfaces for mobile apps that need responsive layout adjustments so that they scale properly across different orientations (portrait vs landscape).
Designing for Mobile Devices
Mobile web design involves more than just creating a site that looks great on desktop computers. It also means designing for mobile devices, which can be less powerful and have different capabilities than their larger counterparts.
For example, you may want to adjust content based on screen size or orientation in order to make your site more accessible and engaging for people using smaller devices like smartphones, tablets, or even e-readers (like Amazon’s Kindle Fire). You should also consider touch gestures when designing your pages; if someone uses their finger or stylus to interact with content on their phone instead of clicking with a mouse or tapping with a fingertip then they’ll need something similar at the other end too (e.g., swipe up from the bottom).
Media Types
The media attribute, which is used to specify the media types that a document is designed for, can be applied to any element and supports both text-based MIME types (e.g., application/pdf) and XML-based MIME types (e.g., application/xhtml+xml).
In addition to defining alternate stylesheets using the element, you may also use it on images in order to specify whether they should be displayed as JPEGs or PNGs—for example:
Pixel Density and Resolution
The next thing you need to know about mobile web development is pixel density. Pixel density, also known as resolution, is the number of pixels on a screen. This can be measured by using an old-school ruler or calculator.
Pixel density is not the same as resolution: it’s how many pixels make up an inch (or other units of measure). Resolution refers to how many individual dots are on your screen—whether black squares or tiny green triangles. You may have heard some people saying that “retina displays” have higher resolutions than non-retina displays, but this isn’t true! Retina displays don’t actually have higher resolutions; they just have more pixels per inch than non-retina ones do.*
Device Pixel Ratio (DPR)
DPR is the ratio between device pixels and CSS pixels. Device pixels are the physical size of a pixel on a device. CSS pixels, on the other hand, are the size of a pixel on the screen. Devices with a DPR of 1 have the same number of devices and CSS pixels.
If you want to know how to calculate your web page’s DPR then here’s what we’re going to do:
Testing on a Mobile Device
To test your app, you should use multiple devices and operating systems. If you plan to release an app on Android, iOS, or any other mobile platform, it is essential that you test it on all of these devices.
Testing your site on a variety of screen sizes will help ensure that your site looks good on all screens and works correctly for users with a wide range of device resolutions. This can help ensure that there are no issues with text being cut off in smaller windows or resizing problems when used in portrait mode (e.g., tablets).
You should also ensure that the same browser is being used when testing – this way, there won’t be any issues with rendering across different browsers like Chrome vs Safari vs Firefox, etc. You might want to include multi-core CPUs if possible too since some mobile devices have more than one core inside them!
Viewport Meta Tag
The viewport meta tag is used to control the size and scaling of your webpage. It allows you to specify how large or small your browser window should be, as well as what aspect ratio it should be at.
The tag contains many different values that can be used individually or combined together in order to achieve specific results:
Summary of Viewport Meta Tag Values and Descriptions
The meta viewport tag is used to control the size of web pages. we can be used in 2 different ways.
To specify a precise width and height for every device that loads your site, or
To tell browsers what they should use as their default values (for example, 800 pixels wide by 600 pixels tall).
