There are more than 30 web browsers currently used today. This number allows avid Internet surfers to choose what browser they want to use. However, there is one major glitch — browsers are not standardized.
Meaning, each browser has its own features and system not common to others. They don’t follow the same set of specifications. For instance, Mozilla Firefox allows the blink HTML element while Internet Explorer does not.
The non-standardization of all web browsers is the main reason why the fonts, image size and display, attributes, HTML syntaxes and structures, meta tags, forms, tables, frames, and HTML properties are sometimes different from one browser to another.
For instance, what is considered big in Apple Safari might not be “big” in Google Chrome. If you have a normal font and font sizes in Opera, chances are, it will not be the same in IE or Firefox.
This compatibility issue is a royal pain to every web developer. The good news is, Dreamweaver has a built-in feature that checks your webpage or HTML file’s compatibility with most major Internet browsers.
To access this tool, open Dreamweaver and go to its side panel. Next, click Files.
