Understanding the BEM Convention in Web Development

BEM, short for Block, Element, Modifier, is a naming system used in web development to organize CSS. It helps developers write clean, easy-to-read code that works well on both small and large projects. The idea behind BEM is to make your CSS styles reusable and easy to maintain.

Here’s how it works:

• Block: This is a standalone part of your website, like a navigation bar or a button.
• Element: These are the smaller pieces within a block, such as an icon inside a button.
• Modifier: These show variations of a block or element, like a button being red or disabled.

For example, if your block is called menu, an element inside it could be menu__item. If you want to style a selected item differently, you could use menu__item--selected.

BEM helps teams collaborate better and keeps your code consistent. Once you get used to it, your CSS becomes much easier to read and update.
