Kuhusu Karatasi ya Muhtasari ya HTML
Karatasi hii ya muhtasari ya HTML inaweka msamiati mzima wa vitambulisho (tags) kwenye ukurasa mmoja unaotafutika: mifupa ya hati na metadata, maudhui ya maandishi, mpangilio wa kisemantiki, viungo na urambazaji, picha na vyombo vya habari, orodha na jedwali, aina za ingizo la fomu, muundo wa fomu na uthibitishaji, vipengele shirikishi, maudhui yaliyopachikwa, sifa za jumla, na entities na herufi maalum.
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.
Karatasi ni bure na inafanya kazi upande wa mteja: chuja safu moja kwa moja kwa kisanduku cha utafutaji, ruka kati ya sehemu kwa jedwali la yaliyomo linalobaki juu, nakili kijisehemu chochote kwa mbofyo mmoja na chapisha ukurasa kuwa rejeo la mezani kwako.
Jinsi ya kutumia Karatasi ya Muhtasari ya HTML
- Pitia sehemu kwa haraka, kuanzia Document skeleton & metadata na Semantic layout kupitia Forms hadi Entities.
- Tafuta tag au sifa kama picture, aria-label au required ili kuchuja kila safu moja kwa moja.
- Ruka hadi Forms: input types unapohitaji kidhibiti sahihi kwa sehemu ya fomu.
- Bofya kijisehemu au ikoni yake ya kunakili ili kunakili HTML kwenye ubao wako wa kunakili.
- Chapisha karatasi ili kupata rejeo la HTML la nje ya mtandao.
Maswali yanayoulizwa mara kwa mara
Sehemu kumi na mbili: mifupa ya hati na metadata, maudhui ya maandishi, mpangilio wa kisemantiki, viungo na urambazaji, picha na vyombo vya habari, orodha na jedwali, aina za ingizo la fomu, muundo wa fomu na uthibitishaji, vipengele shirikishi, maudhui yaliyopachikwa, sifa za jumla, na entities na herufi maalum.
Ndiyo. Imejengwa kuzunguka HTML5 ya kisasa: vipengele vya kisemantiki vya kugawa sehemu, seti kamili ya aina za ingizo, sifa asilia za uthibitishaji, picture na video, details na dialog.
Sehemu mbili zinafanya hivyo: moja inaorodhesha kila aina ya ingizo na matumizi yake, nyingine inashughulikia labels, fieldsets, required, pattern, min na max na uthibitishaji mwingine asilia.
Ndiyo. Bofya kijisehemu chochote au ikoni yake ya kunakili inayojitokeza ukielekeza kipanya na kinatua kwenye ubao wako wa kunakili pamoja na uthibitisho mfupi.
Ndiyo, ni bure kabisa: linatafutika, linachapishika na linaonyeshwa kwenye kivinjari chako bila usajili.
