How to solve problems with specific styles for different browsers

When building web pages, we often face issues with specific styles that only appear on certain browsers. Although all browsers render HTML and CSS in a similar way, there are subtle differences that can cause a page to look or function differently in Chrome, Firefox, Safari, or Internet Explorer. Fortunately, there are several techniques that can help solve these problems and ensure a consistent user experience across all platforms.

1. Identify the problematic browser

The first step is to test our site on different browsers and devices to find out exactly which browser is causing the problem.

The most common compatibility issues will occur with older versions of Internet Explorer, Safari, or some specific versions of Firefox.

We can use tools such as BrowserStack which allows testing the site on various browsers and devices.

2. Use separate styles for specific browsers (conditional styles)

One of the simplest techniques is to use conditional styles which are loaded only for certain browsers. This approach allows us to target specific browsers and apply specific styles just for them.

For example, if we want to add specific styles only for Internet Explorer 9 and earlier versions, we can use the following HTML code:

This code enables loading of the ie9.css style only for users using Internet Explorer 9 or earlier.
That way, we can target only those elements that cause a problem in that browser, without affecting the others.

3. Use CSS frameworks such as Bootstrap

If we want to avoid too much manual tuning for different browsers, the best option is to use a CSS framework like Bootstrap.

Frameworks like Bootstrap already have solutions for many cross-browser compatibility issues.

Using the framework, we get preset styles that are tested on multiple browsers and devices, which can significantly save time and effort.

4. Use Autoprefixer

Autoprefixer is a tool that automatically adds the required vendor prefixes for CSS properties.

Different browsers often require different prefixes for certain CSS properties to support them, such as:

• -webkit- for Chrome and Safari,
• -moz- for Firefox,
• -ms- for Internet Explorer.

For example, if we use CSS to transform an element, some browsers may require the -webkit- prefix while others do not.
With Autoprefixer, we don't need to manually add these prefixes - it will automatically add the right prefix for each browser.

Here is how an example would look without and with Autoprefixer:

5. Use Reset CSS or Normalize.css

One common cross-browser compatibility issue is the default styles applied to HTML elements. For example, some browsers may add margins or padding to h1 elements by default, while others may not.

Reset CSS and Normalize.css are style sets that reset or normalize these defaults, allowing us to have a cleaner and more consistent basic look.

Normalize.css is often a better option than a complete style reset, as it just standardizes cross-browser differences, keeping useful default styles, making the design more consistent between different browsers without overkill. This approach is more modular and easier to debug, but less "aggressive" compared to resetting styles.

Reset CSS completely removes all default styles applied by browsers and returns elements to their initial state, allowing developers to start from a "clean" base. This approach can be difficult for us to debug and maintain due to large selector chains.

6. PostCSS and compatibility plugins

If we use PostCSS or similar CSS libraries, we can use plugins that allow using modern CSS syntax.

For example, some plugins enable the use of new CSS functionalities that are not yet supported in all browsers, but will be automatically transpiled into an older version of the code that is compatible with all browsers.

Conclusion

Troubleshooting problems with specific browsers requires the use of multiple techniques and tools, in order to ensure a consistent appearance and functionality of the site on all platforms.
By combining tools like Autoprefixer, Normalize.css, and CSS frameworks like Bootstrap, we can greatly simplify this process. and eliminate many compatibility issues.
In addition, using conditional styles and specific solutions for older versions of the browser will help the site look and function as it should, regardless of the device or browser users are using.
