Even if you have not written any code in your life, you still will be able to understand how to link the three languages. It might not be your fault — if a bug exists in a browser, then hopefully the vendor will rapidly fix it. It might have already been fixed — for example if a bug is present in Firefox release 49, but it is no longer there in Firefox Nightly (version 52), then they have fixed it.

If you are not sure if front-end web development is for you, and/or you want a gentle introduction before starting a longer and more complete course, work through our Getting started with the web module first. You can work through sections in order, but each one is also self-contained. For example, if you already know HTML, you can skip ahead to the CSS section.

Creating a file directory with multiple folders

So for example, you might be building an e-commerce site that serves customers in North America. Websites should be accessible across different browsers and devices, and to people with disabilities (e.g. screen-reader-friendly).

In this article we discuss the impact images have on performance, and the methods to reduce the number of bytes sent per image. We do however recommend that before you work through this module, you at least get a basic idea of web development by working through our Getting started with the web module. This article should have given you a high-level understanding of the most important concepts you need to know about cross browser testing.

There are several other properties that you can use in CSS to determine the appearance of text. “Text-transform,” for example, allows you to make particular text snippets all capitals or all lowercase, and “font-weight,” will enable you to use the bold or normal weight of a specific font. It doesn’t matter if you want to be a professional web developer, marketer, business owner or tech-savvy intern — if you deal with websites, you need to know CSS. Being able to manage the appearance of a website can provide tremendous professional value; if you know CSS, you’ll be better equipped to achieve at work and command a higher market value for your skill set.

An art or design director oversees all aspects of design work, including both web and non-web design.
