HTML aur XHTML me Kya Difference Hai?
In Dono Markup Languages ke Mukhya Antar ko Samjhein
HTML aur XHTML ka Introduction
HTML (HyperText Markup Language) web pages banane ke liye standard language hai. Yeh bohot flexible hai aur choti-moti errors ko ignore kar deti hai.
XHTML (eXtensible HyperText Markup Language) HTML ka hi ek stricter version hai. Yeh basically HTML hai jise XML ke rules ke anusaar likha gaya hai. Iska matlab hai ki isme har cheez well-formed aur valid honi chahiye.
Mukhya Differences
| Feature | HTML | XHTML |
|---|---|---|
| Full Form | HyperText Markup Language | eXtensible HyperText Markup Language |
| Case Sensitivity | Case-insensitive (<p> aur <P> same hain) | Case-sensitive (Sirf lowercase tags allowed hain) |
| Closing Tags | Optional for some tags (e.g., <p>, <li>) | All tags must be closed. Empty tags (e.g. <br>) must be self-closed (<br />). |
| Nesting | Improper nesting allowed | Proper nesting is mandatory (<b><i>text</i></b>) |
| Attribute Quotes | Optional | Mandatory (e.g., width="100") |
| Error Handling | Forgiving (Browser errors ko fix karne ki koshish karta hai) | Strict (Error hone par page render nahi hota) |
Aaj ke Daur me Kaunsa Zaroori Hai?
Modern web development me, HTML5 standard hai. HTML5 ne XHTML ki zaroorat ko kaafi had tak kam kar diya hai. HTML5 flexible hai lekin developers ko "well-formed" code likhne ke liye encourage karta hai.
Basically, agar aap XML-based systems ke saath kaam kar rahe hain, tabhi XHTML zaroori ho sakta hai. Otherwise, HTML5 hi aage ka raasta hai.
Key Takeaways
- XHTML, HTML ka ek stricter, XML-based version hai.
- XHTML me sabhi tags lowercase me hone chahiye, properly closed aur nested hone chahiye.
- HTML errors ko lekar forgiving hai, jabki XHTML strict hai.
- Modern web development me HTML5 standard hai aur zyada use hota hai.
