👋 Hey there, fellow tech enthusiasts! 🖥️ In today's blog post, we're diving deep into the fascinating world of CSS class names and selectors. 🎉

⚠️ Let's address the burning question right away: which characters are valid in CSS class names/selectors? 🤔💭

📝 Let's start by clarifying that there are some specific rules when it comes to valid CSS class names. Here are the key guidelines you need to keep in mind:

🔢 1. Begin with a letter, an underscore (_), or a hyphen (-). CSS class names must always start with either a letter, an underscore (_), or a hyphen (-). For example, ._myClass or -myClass.

❌ Avoid starting class names with numbers, as it can lead to unexpected behavior and parsing errors. For instance, .42class would be invalid.

📝 So, what's next? Let's explore the characters you can use after the initial character:

✨ 2. Use letters, numbers, hyphens (-), and underscores (_). You have the freedom to incorporate alphanumeric characters, hyphens, and underscores in your CSS class names. For instance, .my_Class123 or #fancy-header.

💡 Pro tip: While you can use uppercase letters, it's generally advisable to stick with lowercase letters in your CSS class names to avoid potential confusion.

🚫 3. Avoid using special characters and reserved symbols. Certain characters, such as spaces or symbols, are not allowed in CSS class names. Let's take a quick look at some examples of invalid characters:

~ ! @ $ % ^ & * ( ) + = , . / ' ; : " ? > < [ ] \ { } | ` #

❌ Using any of these characters in your CSS class names can cause unexpected behavior or rendering issues. So, let's steer clear of them! 😉
