HTML-code. HTML xim codes

Muaj tseeb koj twb ces yuav tsum xws li ib tug lub tswv yim raws li lub HTML-code. Peb tau hnov los ntawm cov phooj ywg, pom nyob rau hauv cov zaub mov ntawm koj tus browser, thiab hais txog. N. Tab sis yog dab tsi? Wb sim kom paub tseeb seb yog dab tsi lub code yog li cas thiab cov ntsiab nws yog tsim.

cov ntaub ntawv

Peb pib nrog ib tug txhais. HTML-code - npav tej web page, uas yog tsim los siv HTML lus.

Qhov no code muaj cim npe uas ua rau lub browser txiav txim qhov zoo ntawm ib daim ntawv yog. Nws qauv yog muab faib ua ob qhov chaw: lub taub hau - title ntawm cov ntaub ntawv, uas npe rau sab title, raws li zoo raws li cov lus qhia txog cov ntaub ntawv nws tus kheej, thiab lub cev - lub cev ntawm cov ntaub ntawv, uas koj muab cov ciaj ciam ntawm cov nplooj ntawv.

Nyob rau hauv thiaj li yuav tsim ib tug ntau dua los yog tsawg dlej web page, sau los ntawm kos, yuav tsum tau tshawb cim npe siv los ntawm cov lus no, lawv tsis, raws li zoo raws li paub cov HTML xim lis dej num.

cim npe

Tag - caij ntawm HTML. Nrog nws, koj yuav tau teem lub font, xim, loj hauv cov ntawv nyeem, muab tshuaj txhuam nws mus rau hauv lub rooj thiab cov duab, hom ntawv, tsim headers, mus, thiab cov nplooj ntawv xim.

Tags yeej ib txwm nyob nrog rau hauv lub nkhaus - <>, thiab hais tias yog dab tsi teev lawv sib nrug los ntawm lub ntsiab ntawv nyeem, uas yog tso tawm kom pom nyob rau ntawm nplooj thaum browsing. Nws muaj ob hom - ob chav thiab ib.

Kev nyeem muaj li ntawm cov lus qhib tag thiab kaw, thaum lub caij nyoog kawg no tom qab ib tug sab laug lub bracket yog ncaj slensh. Piv txwv li: & lt; b & gt; text & lt; / b & gt;.

Nruab nrab ntawm ob cim npe yog cov ntawv nyeem, cov lus, daim duab, los yog lwm yam khoom, uas yog tso tawm rau ib tug web page.

Solo kuj muaj xws li ib tug ib lossis thiab tsis muaj ib tug rau pem hauv ntej luaj. Piv txwv li: & lt; hr & gt;.

Tags yuav muaj tsis uas yuav tau teem caij siv tshwj xeeb lis dej num rau HTML.

Tsis tas li ntawd nco ntsoov tias feem ntau cov cim: aub, khawb, trademark cim yog ntau dua los yog sib npaug zos rau, tsawg tshaj li, los yog sib npaug zos rau, thiab ntau lwm tus neeg - yog ib tug tshwj xeeb lub rooj, uas txhais tau tias cov ua cim code cov ntaub ntawv. Qhov no code pib nrog ib tug ampersand, tom qab uas muaj peev xwm yuav muaj tsab ntawv Mnemonic nws los, los yog lub phaus kos npe rau nrog ib tug peb-ntiv cim code. Thaum kawg nws yog nco ntsoov muab ib tug semicolon.

Ntsiab cim npe

Yuav ua li cas yog cov HTML-code, peb to taub, tam sim no peb yuav ua tiag sau lub ntsiab cim npe, uas yuav pab tau, yog hais tias tsis mus tsim lawv tus kheej web pages, ces tsawg kawg yog rau cov ntawv luam tsim.

paired:

• & Lt; lub cev & gt; - nws muaj qhov yooj yim tsis muaj daim ntawv xws li cov tom qab kob ntawm kev mus, thiab lwm yam liaj teb;
• & Lt; p & gt; - qhia ib pawg lus;
• & Lt; b & gt; - xaiv cov ntawv nyeem nyob rau hauv bold;
• & Lt; kuv & gt; - ntawv qaij;
• & Lt; u & gt; - underlines cov ntawv nyeem;
• & Lt; s & gt; - cancels cov ntawv nyeem;
• & Lt; SUP & gt; - teev cov ntawv nyeem raws li ib tug superscript;
• & Lt; sub & gt; - subscript;
• & Lt; font & gt; - teev cov font paramerty: loj, me, font, xim;
• & Lt; div & gt; - nrog nws koj yuav dlhos koj phau ntawv;
• & Lt; h & gt; - Tag headers;
• & Lt; ib tug & gt; - nrog rau cov kev pab los ntawm txheej siv;
• & Lt; rooj & gt; - Pab mus tau ntxig rau hauv lub rooj ntawv no, nws yog txuas mus rau cim npe & lt; tr & gt; (Kab) thiab & lt; td & gt; (Cell).

tib:

• & Lt; br & gt; - ib, ntawv wrapping, nram qab no tom qab nws, nyob rau ib nplooj ntawv tshiab;
• & Lt; hr & gt; - nws yuav muab tso rau hauv cov ntawv nyeem ntawm lub kab rov tav kab.

Nws yog ib nqi sau cia hais tias lub cim npe feem ntau yog muab nyob rau hauv ib txoj kab tshiab. Qhov no yog ua li cas rau lub yooj yim ntawm tsis tsuas yog lub coder, tab sis kuj cov neeg uas yuav saib cov cai nyob rau HTML.

tsis tag

Peb twb sib tham nrog koj qhov yooj yim cim npe, uas ua rau koj xav paub. Ntawm cov hoob kawm, peb tau sau tseg, tsis yog txhua txhua, tab sis txawm no yam tsawg kawg nkaus yuav tsum yog txaus los tsim lawv tus thawj nplooj ntawv Web site.

Tab sis ob peb paub ib co cim npe yuav tsum tau xyuas lub ciaj ciam uas yuav tsum tau muab teem. Nyob rau hauv no tsab xov xwm, peb yuav tsuas ua ib tug nyuag saib xyuas, peb piav qhia txog cov feem ntau nquag siv. Mus saib lawv koj yuav, qhib tej HTML-code.

Wb tsis tseem pleev xim rau ib tug tag qhov kev xaiv no yog tsim, vim muaj ntau ntawm lawv yog siv nyob rau hauv feem ntau ntawm cov web markup commands:

• ntsej muag - qhia txog cov font hom;
• loj - qhia txog qhov luaj li cas;
• xim - teev cov xim;
• dlhos - kawm tuab si lug;
• lub npe - lub npe;
• href - siv no parameter teev cov kev siv qhov chaw nyob;
• alt - lwm ntawv nyeem;
• dav - dav;
• qhov siab - qhov siab;
• tom qab - wallpaper;
• bgcolor - keeb kwm yav dhau.

Qhov no yog tsis yog txhua txhua lub tsis, peb tau sau tseg xwb cov feem ntau siv thiab paub.

Tom qab equated parameter thiab ces npe tus nqi hais. Peb qhia rau koj nyob rau hauv txoj kev loj hlob ntawm cov Web sites thiab cov nplooj ntawv siv tshwj xeeb cov phau ntawv los yog phau ntawv nyob rau hauv thiaj li yuav paub tsis tau tsuas yog qhov yooj yim tsis, tab sis kuj muaj txoj cai los nug lawv.

xim rooj

Yog li ntawd, nrog cov yooj yim cim npe thiab lawv cov chaw, peb to taub, tam sim no cia saib cov HTML xim lis dej num. Nws yog nrog lawv pab, koj yuav tau qhia kom meej rau cov xim ntawm cov ntawv, cov nplooj ntawv, los yog ib co ntawm nws cov ntsiab.

Novice webmasters yuav tsum paub hais tias muaj yog ib tug tshwj xeeb xim rooj nyob rau hauv uas cov lis dej num yog muab rau txhua lub xim. Muaj ib tug tag nrho ntawm 16 yooj yim xim uas yuav tau teem caij tsis tau tsuas yog los ntawm txoj kev ntawm lub rooj, tab sis tsuas yog taw npe nyob rau hauv lus Askiv. Tsis tas li ntawd nws yog tau mus ntxiv cov lus teeb thiab tsaus, nug tus cai ntxoov ntxoo.

Muaj kuj yog ib lub rooj ntawm kev ruaj ntseg cov xim, uas muaj 216 tag nrho cov hom ntawm zib suab thaj.

Nco ntsoov tias kev siv ntawm cov ntxhuav yog ntau npaum li cas yooj yim. Lawv muab hex xim code. Nyob rau hauv cov ntaub ntawv no, koj yuav tam sim ntawd pom cov xim. Txhua code pib nrog ib phaus kos npe rau, ua raws li los ntawm peb cov officers ntawm tej yam tshwm sim, uas tuab cov kev siv ntawm cov thawj xim: liab, ntsuab, thiab xiav.

Qhov no code ib tsab luam thiab hloov koj yam chaw nyob rau hauv lub tag.

Yuav ua li cas mus saib tau tus code ntawm cov nplooj ntawv

Yog hais tias koj xav nyob rau hauv cov creation ntawm nplooj ntawv Web site, ces koj yuav yeej yuav nthuav los saib qhov chaw HTML-code uas koj nyiam los yog hais tias koj mus saib ntau heev.

Tab sis yuav ua li cas ua tau nws? Muaj ob txoj kev, ib tug ncaj yooj yooj yim thiab straightforward. Tus thawj - qhib lub qhov kev kawm page thiab nias tus yuam sij ua ke Ctrl + U. Nyob rau hauv lub qhov rai tshiab, rau qhov chaws ntawm cov nplooj ntawv yuav tshwm sim, uas koj yuav pom thiab tshawb.

Qhov thib ob txoj kev - nias rau sab laug nas khawm thiab xaiv nyob rau hauv lub nco-daim ntawv teev, xaiv "qhov code." Tseem, peb pom zoo kom koj siv cov thawj txoj kev, vim txoj kev siv cov kub tuav yog npaum li cas yooj yim dua thiab yooj yim.

Nco ntsoov tias los ntawm kev nyeem cov code, koj yuav tau saib cov lus rau nws, lossis sau nyob rau hauv lub "Saib", uas zoo li no: & lt;! & Gt;. Yog li nws cov lus sau tom qab ib tug exclamation mark. Nyob rau hauv koj browser, nws tsis yog tso tawm kom pom. Ib daim ntawv sau feem ntau rau lwm programmers thiab web designers tau to taub zoo li cas ntawm cov ntaub ntawv chav tsev yog hauv qab no seb yog qhia los yog tias daim code.

tshawb pom

Sau nyob rau hauv HTML code yog tsis nyuaj li thaum tej zaum nws yuav zoo li thaum xub thawj siab ib muag. Tshwj xeeb tshaj yog hais tias koj xav mus tsim unpretentious thiab unpretentious chaw, online tutorials rau HTML-raws li , thiab thiaj li nyob. N. kawm qhov yooj yim hauv paus ntsiab lus ntawm lub markup cim npe thiab nws tsis siv sij hawm ntau lub sij hawm. Koj muaj txaus txawm tias ib tug ob peb hnub mus rau pib los tsim lawv tus kheej tej yaam num.

Nco ntsoov hais tias yog koj xaiv rau kawm no markup lus, yuav tau ceev faj. Feem ntau cov teeb meem tshwm sim vim hais tias ntawm kev lam ua: unclosed cim npe paired incorrectly tshuaj tsis, typographical uas tsis - tag nrho cov no hawv ua phem rau tig mus rau hauv ib tug yuam kev, koj muaj peev xwm nrhiav ntev txaus. Tab sis nyob rau hauv Feem ntau, kom paub HTML-page layout yog heev nthuav.
