Introducere XHTML

Introducere XHTML

XHTML sau Limbajul de marcare hipertext extensibil este un amestec de HTML și XML, foarte asemănător cu HTML dar mai stricte. Este ca un cadru de reguli pentru a crea pagini web pe care browserele le înțeleg cu ușurință. Spre deosebire de HTML, trebuie să fii atent și să urmezi întocmai regulile. Majoritatea browserelor îl acceptă. Gândiți-vă la asta ca la o modalitate mai precisă de a scrie cod web.

Cuprins

Istorie

A fost dezvoltat de World Wide Web Consortium (W3C) și îi ajută pe dezvoltatorii web să treacă de la HTML la XML. Cu XHTML, dezvoltatorii pot intra în lumea XML cu toate caracteristicile sale, asigurând în același timp compatibilitatea anterioară și viitoare a conținutului. Familia XHTML include trei tipuri de documente; primul este XHTML 1.0, care a fost recomandat de W3C pe 26 ianuarie 2000. Al doilea este XHTML 1.1, care a fost recomandat de W3C pe 31 mai 2001.

Al treilea este XHTML5, un standard folosit pentru dezvoltarea unei adaptări XML a specificației HTML5. Un document XHTML trebuie să aibă o declarație XHTML.

Elemente ale XHTML:

Element XHTML Descriere
> Folosit pentru a declara definiția tipului de document (DTD), specificând regulile pentru limbajul de marcare, asigurând randarea corectă în browsere.
> Include întregul document HTML sau XHTML, servind ca element rădăcină.
> Conține metainformații despre document, cum ar fi titlul, setul de caractere, foile de stil legate și alte elemente esențiale.
> Imbricat în secțiunea de cap, specifică titlul documentului, afișat în bara de titlu sau fila browserului.
> Include conținutul paginii web, inclusiv text, imagini, link-uri și alte elemente HTML. Reprezintă partea vizibilă a documentului afișată în browser.

La crearea unei pagini web XHTML, este necesar să includeți o declarație DTD (Document Type Definition). Există trei tipuri de DTD care sunt discutate mai jos:

DTD de tranziție:

Este acceptat de browserele mai vechi care nu au suport pentru foi de stil în cascadă încorporate. În eticheta body sunt incluse mai multe atribute care nu sunt permise în DTD strict.

Sintaxă:

 PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'DTD/xhtml1-transitional.dtd'>>>>   

Exemplu: În acest exemplu vom vedea codul pentru scrierea unui document XHTML cu un exemplu.
