The latest progress when it comes to CSS is focused on being a time saver and improving accuracy. This is done through CSS preprocessors. Instead of being restrictive, they allow for the creation of variables.

Developers commonly use these so they don’t have to go through the hassle of copying codes and pasting it. This is basically a software tool that is very important to the developer. Its function is to process specific data so that it can be understood by other programs. It is a time saver in that it often reduces the amount of code that needs to be written. While this offers a lot of advantages, preprocessors do have some limitations too. They cannot be read using JavaScript nor can you change them with this. They don’t identify the DOM’s structure and there is no ability for dynamic changing.

Now, the latest news about this indicates CSS custom properties have been developed which is good news for developers. As with anything, there is always a learning curve and it comes down to the syntax here with these properties. The good news is that you only need to learn them once, which is not the same with individual preprocessors which each time you use a new one, you have to determine how the variables are declared. With the properties, once you have learned the syntax, you can use it again with any browser.

It is well worth learning about CSS custom properties because of the benefits and features that it offers. Learning how to work with the variables is not all that difficult. Once you delve into the CSS custom properties, you will soon see that you can rely on variables scoping and still are able to add the cascading of the CSS properties. You will see that these properties recognize the DOM’s structure and are dynamic.
