Hello dosto! Aaj hum baat karne wale hain 'Shadow DOM' ke baare mein, jo web development ka ek important feature hai.
Shadow DOM, web components ka ek hissa hai jo encapsulation ka concept use karta hai. Iska matlab hai ki aap apne HTML elements aur styles ko doosre elements se alag rakh sakte hain. Isse aapki application ki styling aur functionality ko behtar tarike se manage karne mein madad milti hai.
Jab aap Shadow DOM create karte hain, tab aap ek 'shadow root' banate hain jo ki ek isolated DOM subtree hota hai. Yeh subtree aapke main DOM se alag hota hai, isliye isme aap jo bhi styles aur scripts use karte hain, wo sirf usi shadow tree par apply hote hain, main DOM par nahi.
Example ke liye, agar aap ek custom button bana rahe hain, toh aap us button ke liye apne styles ko Shadow DOM mein define kar sakte hain, jisse ki wo kisi doosre styles se affect na ho. Yeh feature particularly jab aap third-party components develop karte hain tab kaafi useful hota hai.
Lekin, Shadow DOM ka use karne se pehle aapko ye ensure karna hoga ki aapke target browsers is feature ko support karte hain. Abhi kai modern browsers isse support karte hain, par kuch purane versions mein yeh nahi chalega.
Toh yeh tha Shadow DOM ka ek chhota sa introduction
