CSS Overflow & Clipping Property Kya Hai?
1. CSS Overflow & Its Properties:
CSS Overflow ek property hai jo ek element ke content ke behavior ko control karti hai jab wo uske defined dimensions se bahar nikalta hai. Iske main values hoti hain: visible (default, content overflow dikhta hai), hidden (extra content chhup jata hai), scroll (scrollbar add hoti hai chahe zaroori ho ya nahi), aur auto (scrollbar sirf jab zaroori ho tab dikhai deti hai). Overflow mostly width aur height ke saath use hota hai taaki layout aur UX better ho sake. Iska use scrollable divs ya unwanted content overflow ko handle karne ke liye hota hai.
Overflow ke 4 main values hote hain:
(A) visible (default):
Visible (default) ka matlab hai ki jab kisi element ka content uske box se bada hota hai, tab bhi woh content clearly dikhai deta hai aur kisi bhi tarah ka clipping ya scroll effect nahi hota. Yeh CSS overflow property ka ek default value hota hai, jo ensure karta hai ki pura content page par visible rahe bina kisi limitation ke. Iska use tab hota hai jab hume content ko full visibility ke saath display karna ho bina kisi scroll ya hidden effect ke. Agar content container se bahar chala jaye, toh bhi koi cut-off effect nahi hota.
div {
overflow: visible;
}Use Case: Jab aapko extra content clip nahi karna ho.
(B) hidden:
hidden overflow ek CSS property hai jo tab apply hoti hai jab ek element ka content uske defined dimensions se bahar jata hai. Jab overflow: hidden; use kiya jata hai, toh extra content cut ho jata hai aur kisi bhi tarah visible nahi hota. Yeh property mostly tab use hoti hai jab unwanted scrolling ya extra visible content ko hatana ho. Yeh block-level aur inline elements dono pe kaam karta hai. Iska use animations, hover effects aur clean UI banane ke liye bhi hota hai. Agar content ko dekhna zaroori ho, toh scroll ya auto use karein.
div {
overflow: hidden;
}Use Case: Jab unwanted overflow ko hide karna ho.
(C) scroll:
Scroll ek CSS property hai jo overflow content ko control karti hai. Jab kisi element ka content uske defined height ya width se zyada hota hai, tab overflow: scroll; use karne se scrollbar automatically show hoti hai. Yeh dono direction (horizontal & vertical) me kaam karta hai, user ko extra content dekhne ka option deta hai. Agar sirf ek direction me scroll chahiye toh overflow-x: scroll; ya overflow-y: scroll; use kiya jata hai. Yeh property mostly web layouts aur responsive design ke liye useful hoti hai, jisse user experience improve hota hai. Proper usage scrolling issues ko solve karta hai.
div {
overflow: scroll;
}Use Case: Jab hamesha scrollbar dikhana ho chahe zarurat ho ya nahi.
(D) auto:
In CSS overflow ka matlab hai ki content automatically adjust hoga based on container ke size ke hisaab se. Agar content container ke andar fit ho jaye, toh scrollbar nahi dikhega. Lekin agar content zyada ho, toh browser decide karega ki scrollbar dikhana hai ya nahi, user ke system settings aur browser behavior ke basis par. Yeh default behavior hota hai aur mostly flexible layouts mein use kiya jata hai. Overflow: auto ka istemal karne se scrolling ka option sirf tabhi aata hai jab zaroorat ho, jisse layout clean aur user-friendly dikhta hai.

overflow: auto;
}Use Case: Jab automatically scrollbars enable karna ho sirf tab jab zarurat ho.
