Background ইমেজকে fixed করা
সাধারনত যখন ইমেজকে repeat horizontally বা no-repeat করা হয় এবং নিচে অনেক
টেক্সট বা অবজেষ্ট থাকে, তখন নিচের দিকে স্ত্রুল করতে থাকলে উপরের ব্যকগ্রাউন্ড
ইমেজও স্ত্রুল হয়। এটি বন্ধ করার জন্য অর্থ্যাৎ টেক্সট বা অবজেক্ট ক্রল হবে কিন্তু
ব্যাকগ্রাউন্ড ইমেজ নড়বে না, এজন্য background-attachment প্রোপার্টিজ এর সাথে Value দিতে হবে fixed। নিচের মত
প্রোগ্রাম তৈরী করে দেখুন।

Brackground ইমেজের পজিশন নির্নয়
ডিফল্ট হিসাবে ইমেজের পজিশন থাকে উপরে (Top) এবং বামদিকে (leff). background-position প্রোপার্টিজ দ্বারা value কে left, right, top, bottom ইত্যাদির মাধ্যমে ইমেজের পজিশন নির্নয় করে দেওয়া
যায়। এক্ষেত্রে ইমেজ ডানদিকে নিলে right margin ঠিক করে দিতে হবে। নিচের মত
