We all know naming a class is always been a headache but using BEM we can avoid name collisions and reduce the pain of modifying CSS classes when changes are needed to be made. While working with the larger project is hard to keep track of each class name so it's always been helpful to follow some patterns and that's why many companies use BEM methodology in their projects.
BEM, or Block-Element-Modifier, is a popular CSS methodology that helps developers write modular and reusable code. It is especially useful for large-scale projects where many different developers may be working on different parts of the codebase. In this blog post, we will explain what BEM is, why it's useful, and how to use it in your own projects.
At its core, BEM is a naming convention for CSS classes. It works by breaking down your HTML elements into three different parts: blocks, elements, and modifiers. Blocks represent the highest level of abstraction and correspond to a specific section of the page. Elements are the parts of the block that make up its functionality and are nested within the block. Modifiers are used to change the appearance or behavior of an element or block.
One of the main benefits of BEM is that it makes your CSS code more modular and reusable. By breaking down elements into blocks, elements, and modifiers, you can easily reuse code across different sections of the page. This means that you can write less code, and it will be more maintainable in the long run.
Another benefit of BEM is that it makes your code more readable. By using a consistent naming convention, other developers can easily understand how your code is organized and how different elements relate to each other. This helps to reduce confusion and errors, making it easier to work on large-scale projects.
To use BEM in your own project, you'll need to start by defining your blocks, elements, and modifiers. For example,
It's important to note that BEM is not the only CSS methodology out there and that you should choose the one that best fits your project's needs and team's habits. BEM is a powerful tool that can help you write more modular and reusable CSS code, but it's not always the right choice for every project.
In conclusion, BEM is a powerful CSS methodology that can help you write more modular and reusable code. By breaking down elements into blocks, elements, and modifiers, you can easily reuse code across different sections of the page. BEM also makes your code more readable, which helps to reduce confusion and errors. By using BEM in your own project, you can improve the maintainability and scalability of your codebase.
