XHTML poate fi considerat ca \u00eencruci\u015farea dintre HTML \u015fi XML \u00een multe privin\u0163e, fiind o reformulare a HTML \u00een XML. XHTML 1.0 a devenit o recomandare World Wide Web Consortium (W3C) pe data de 26 ianuarie 2000.<\/p>\n<p style=\"text-align: justify;\">Practic XHTML este un inlocuitor modern al mai vechiului limbaj HTML, fiind aproape identic cu standardul HTML 4.01, o versiune imbunatatita, mult mai stricta si mai curata a standardului HTML 4.0. Abstractizand putin, afirmam ca XHTML reprezinta o definire de tip XML a unui document HTML, pe scurt o combinatie intre HTML si XML. Avantajele unei aplicatii XHTML sunt multiple: pot fi citite de toate dispozitivele XML, in timp ce pastreaza compatibilitatea cu toate browserele de Internet mai vechi sau mai noi fara a necesita specificatii suplimentare. XHTML + TIME este o extensie a limbajului XHTML, oferind documentelor Web suport pentru temporizare si sincronizare multimedia. Astfel, folosind cateva elemente si atribute noi, unei pagini XHTML i se poate adauga continut grafic, audio sau video, care poate fi sincronizat cu alte elemente de-a lungul unui cadru temporal precizat de autorul acelei pagini. Versiunea XHTML + TIME 1.0 a fost disponibila pentru prima data in Internet Explorer 5, iar in prezent XHTML + TIME 2.0 este recunoscut de Internet Explorer, versiunile 5.5 si 6.<\/p>\n<p style=\"text-align: justify;\">Beneficii:<\/p>\n<p style=\"text-align: justify;\">Pagini Web care au continut dynamic XHTML + TIME poate fi utilizat pentru a adauga paginilor Web continut interactiv, dinamic. De exemplu, pot fi create prezentari Web sub forma de slide-show, in cadrul lor fiind sincronizate fluxuri de date textuale, audio, video sau grafice. Aceste prezentari pot fi temporizate, interactive sau combinate.<\/p>\n<p style=\"text-align: justify;\">Utilizare facila:<\/p>\n<p style=\"text-align: justify;\">Facilitatile oferite de XHTML + TIME aduc un set de atribute si elemente noi celor deja existente in limbajul XHTML, astfel ca toate notiunile anterioare de XHTML raman utile pentru proiectarea de pagini Web in XHTML + TIME. Pentru a permite utilizarea facila a mai multor elemente XHTML, acestea pot fi grupate in relatii ierarhice. Gruparea poate fi utila si pentru a preciza daca obiectele multimedia apar si dispar in mod secvential in cadrul paginii Web, sau fiecare are o temporizare independenta de a celorlalte.<br \/>\nSuport pentru scripting<\/p>\n<p style=\"text-align: justify;\">Limbajele script JavaScript sau VBScript permit si mai mult extinderea flexibilitatii si interactivitatii elementelor temporale din cadrul paginilor Web. XHTML + TIME ofera un model de obiecte complet, care extinde actualul model DHTML, care consta dintr-un set de proprietati, metode si evenimente pentru adaugarea de trasaturi interactive paginilor Web.<\/p>\n<p style=\"text-align: justify;\">Elementele XHTML + TIME se comporta in mod diferit la adaugarea atributelor temporale, in functie de tipul elementului respectiv. Astfel, distingem doua tipuri de elemente in limbajul XHTML + TIME: \u2013 elemente de continut : toate elementele care descriu continutul ce urmeaza a fi afisat in pagina, inclusiv elementele noi introduse de XHTML + TIME, care se refera la obiecte multimedia (t:animation, t:audio, t:img, t:media si t:video). Cele mai utilizate elemente de continut din XHTML sunt p, div, span, precum si elementele pentru descrierea de tabele. Prin adaugarea de atribute XHTML + TIME unui element de continut, poate fi definita o aparitie periodica a elementului respectiv. \u2013 elemente de stil : descriu stilul de afisare pentru un element. Dintre cele mai utilizate elemente de stil amintim: b, i si em. Atributele aplicate unui element de stil determina atasarea si inlaturarea unor stiluri de afisare pe parcursul timpului.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201ceXtensible HyperText Markup Language\u201d, sau XHTML, este un limbaj de marcare ce are acelea\u015fi capabilit\u0103\u0163i expresive ca \u015fi HTML, dar cu o sintax\u0103 mai strict\u0103.
