Themes can cause troubles too because features and functionalities get added and new patterns get introduced over time. There are times, for instance, when you will be working on a project that is developed by another team and you need to understand how to go about its requirements from thereon, add on and minimise duplication. Or, you may think about sizing up a theme to make sure that you are efficacious and not growing out of the proportion.
 
There is a plentitude of tools and methodologies that offer great insights so that you can keep managing your theme efficiently over time. You can leverage CSS analysis tools like Parker. It acts as a stylesheet analysis tool and runs metrics on your stylesheets and reports on their intricacies. Analyze CSS can also be used for analysing CSS selectors intricacy and performance.
 
A lint tool can be used that helps in performing static analysis for source code and flags patterns that are problematic for the developer and may lead to errors. So, you can also use CSS Lint for automated linting of cascading stylesheets.
 
The BEM methodology (Block, Element, Modifier), which is a popular naming convention for classes in HTML and CSS, can help in providing a better understanding of the relationship between HTML and CSS in a given project.
 
There is also a Scalable and Modular Architecture for CSS (SMACSS) that is understandable and can save your styles from cascade issues when you do not require it thereby making your HTML cleaner.
 
These are some of the important tools and methodologies that can be of great help and assist in auditing theme. After all, for improving your work with stylesheets, you need to organise it properly.
