EPUB क्या है? EPUB फ़ॉर्मेट की संपूर्ण गाइड

EPUB (इलेक्ट्रॉनिक प्रकाशन) एक ओपन ईबुक फ़ॉर्मेट है जो HTML और CSS पर आधारित है, जो टेक्स्ट को पुनः प्रवाहित और विभिन्न स्क्रीन आकारों के अनुसार अनुकूलित करने की अनुमति देता है, जिससे यह अधिकांश ई-रीडर्स के लिए डिजिटल पुस्तकों का मानक फ़ॉर्मेट बन जाता है।
