Despre Fișă de referință HTML
Această fișă de referință HTML pune întregul vocabular de taguri într-o singură pagină căutabilă: scheletul documentului și metadatele, conținut text, layout semantic, linkuri și navigare, imagini și media, liste și tabele, tipuri de input pentru formulare, structura și validarea formularelor, elemente interactive, conținut încorporat, atribute globale, și entități și caractere speciale.
It is as useful for the details as for the tags: which input type to use for a date or a colour, the required and pattern validation attributes, the semantic difference between article, section and aside, or the entity code for a non-breaking space and a curly quote.
Fișa este gratuită și client-side: filtrează rândurile live cu caseta de căutare, sari între secțiuni cu cuprinsul lipicios, copiază orice fragment de cod cu un singur clic și tipărește pagina ca referință de birou.
Cum să utilizați Fișă de referință HTML
- Parcurge secțiunile, de la Scheletul documentului și metadate și Layout semantic, prin Formulare, până la Entități.
- Caută un tag sau un atribut precum picture, aria-label sau required pentru a filtra fiecare rând live.
- Sari la Formulare: tipuri de input atunci când ai nevoie de controlul potrivit pentru un câmp.
- Dă clic pe un fragment de cod sau pe iconița lui de copiere pentru a copia HTML-ul în clipboard.
- Tipărește fișa pentru o referință HTML offline.
