Pernahkah Anda menemukan halaman web yang terasa berat atau kurang rapi saat dibuka di ponsel, padahal isinya sangat penting untuk dibagikan ke grup belajar atau rekan kerja? HTML, fondasi utama web, memang fleksibel. Namun, seringkali fleksibilitas ini membuat struktur dokumen menjadi kurang ketat, terutama jika ditulis secara terburu-buru. Di sinilah XHTML hadir sebagai "saudara" HTML yang lebih disiplin. Dengan aturan penulisan yang lebih ketat, XHTML memastikan dokumen web Anda memiliki struktur yang valid dan mudah diurai, mirip seperti merapikan tumpukan buku agar mudah ditemukan saat dibutuhkan.
