Buku losavuta kugwiritsa ntchito Makhalidwe apadera mu HTML
Mawebusaiti omwe mumawachezera pa intaneti amamangidwa pogwiritsa ntchito ma HTML omwe amauza oyang'ana pa webusaiti zomwe zili patsamba ndi momwe angaperekere zithunzi kwa owonerera. Makhalidwewa ali ndi zomangamanga zomangika zomwe zimatchedwa zinthu, zomwe owona tsamba lazamasamba samaziwona. Makhalidwewa amakhalanso ndi malemba omwe amawoneka ngati omwe ali pamitu ndi ndime zomwe zinapangidwira owona kuwerenga.
Udindo wa Makhalidwe apadera mu HTML
Mukamagwiritsa ntchito HTML ndikulemba malemba okonzedwa kuti awoneke, nthawi zambiri simukusowa zida zapadera - mumagwiritsa ntchito makina anu a kompyuta kuti muwonjezere malemba kapena malemba oyenera. Vuto limabwera pamene mukufuna kulemba chikhalidwe mwazolembedwa zomwe HTML zimagwiritsa ntchito ngati mbali ya code yokha. Zotsatilazi zikuphatikizapo zilembo
Malembo apadera ndi malemba ena a HTML okonzedwa kuti asonyeze zilembo zomwe zimagwiritsidwa ntchito mu code HTML kapena kuphatikiza zilembo zomwe sizipezeka pa makiyi omwe mawonedwe amawona. HTML imatembenuza malemba apaderawa ndi zilembo zamtundu kapena chikhalidwe kuti zikhoze kuphatikizidwa mu HTML, kuwerenga ndi osatsegula, ndikuwonetseratu bwino alendo a malo anu kuti awone.
Otsatira a HTML apadera
Otsatira atatu ali pachimake cha syntax ya HTML code. Musamazigwiritse ntchito m'magawo owerengeka a tsamba lanu losalemba popanda kuwatumizira poyamba kuti muwonetse bwino. Ndizoposa zazikulu, kuposa, ndi ampersand. Mwa kuyankhula kwina, musagwiritse ntchito zochepa-kuposa chizindikiro < mu HTML yanu pokhapokha ngati pali chiyambi cha tsamba la HTML. Ngati mutero, khalidweli limasokoneza makasitomala, ndipo masamba anu sangapereke monga mukuyembekezera. Zithunzi zitatu zomwe inu simukuyenera kuziwonjezera osadziwika ndi:
- chizindikiro chochepa <
- chachikulu kuposa chizindikiro >
- ampersand &
Mukamalemba malembawa mwachindunji mu HTML yanu-kupatula ngati mukuwagwiritsa ntchito monga zilembo zamtundu wa makalata mu encoding kwa iwo, kotero amawoneka molondola m'malemba owerengeka:
- chizindikiro chochepa- & lt;
- chachikulu kuposa chizindikiro - & gt;
- ampersand - & amp;
Chikhalidwe chilichonse chapadera chimayamba ndi ampersand-ngakhale khalidwe lapadera la ampersand limayamba ndi khalidwe ili. Olemba apadera amatha ndi semicolon. Pakati pa anthu awiriwa, muwonjezerapo chilichonse chomwe chili choyenera kuti mukhale ndi khalidwe lapadera lomwe mukufuna kuwonjezera. Lt ( zosakwana ) imapanga zochepa-kuposa chizindikiro pamene zikuwoneka pakati pa ampersand ndi semicolon mu HTML. Mofananamo, gt imapanga wamkulu kuposa chizindikiro ndi amp ampandand pamene ali pakati pa ampersand ndi semicolon.
Anthu Odziwika Omwe Simungapange
Chikhalidwe chilichonse chomwe chingapangidwe mu Latin-1 chikhalidwe chosankhidwa chikhalidwe chingathe kumasuliridwa mu HTML. Ngati sichikuwonekera pamakina anu, mumagwiritsa ntchito chizindikiro cha ampersand ndi code yapaderadera yomwe yapatsidwa kwa chikhalidwe pambuyo pa semicolon.
Mwachitsanzo, "maubwenzi abwino" a chizindikiro cha chilolezo ndi kukopera; ndi & malonda ; ndilo chizindikiro cha chizindikiro cha chizindikiro.
Makhalidwe abwinowa ndi osavuta kukumbukira komanso osavuta kuwakumbukira, koma pali malemba ambiri omwe alibe maubwenzi abwino omwe amakumbukira mosavuta.
Makhalidwe onse omwe angayesedwe pawindo ili ndi code yofanana ya decimal. Mukhoza kugwiritsa ntchito nambala yanuyi kuti muwonetse khalidwe lililonse. Mwachitsanzo, decimal ndiyo chizindikiro cha chilolezo- & # 169; -masemedwe momwe manambala amatha kugwira ntchito. Zimayambika ndi ampersand ndi kutha ndi semicolon, koma mmalo mwa maubwenzi ovomerezeka, mumagwiritsa ntchito chiwerengero cha chiwerengero chotsatiridwa ndi chiwerengero cha nambala yapadera kwa chikhalidwe chimenecho.
Maubwenzi ochezeka ndi osavuta kukumbukira, koma ma code amtunduwu amakhala odalirika kwambiri. Mawe omangidwa ndi zidziwitso ndi XML mwina sangakhale nawo maubwenzi onse omwe amatha kufotokozera, koma amathandizira ma nambala.
Njira yabwino yopezera zizindikiro za chiwerengero kuti zikhale zofanana ndizoyilo zomwe mungapeze pa intaneti. Mukapeza chizindikiro chomwe mukuchifuna, lembani ndi kusunga nambala ya chiwerengero mu HTML yanu.
Zina mwazinthu zachikhalidwe zikuphatikizapo:
- Ndalama zamtengo
- Mathematical codes
- Zizindikiro za zizindikiro
- Zizindikiro za kutchulidwa
- Zizindikiro za ma diacritics
Osalankhula Chilankhulo cha Chingerezi
Malembo apadera samangokhala ku Chingerezi. Olemba apadera m'zinenero zomwe sizinenero za Chingerezi akhoza kufotokozedwa mu HTML kuphatikizapo:
Nanga Mauthenga a Hexadecimal Ndi Chiyani?
Code ya hexadecimal ndi mawonekedwe ena owonetsera malemba apadera mu code HTML. Mukhoza kugwiritsa ntchito njira iliyonse yomwe mukufuna pa tsamba lanu la webusaiti. Inu mumawayang'ana iwo mu khalidwe amakhala pa intaneti ndi kuwagwiritsa ntchito mofanana momwe inu mumagwiritsira ntchito maubwenzi abwino kapena ma numeric.

Malangizo
Ziribe kanthu njira yomwe mumagwiritsira ntchito, sungani malingaliro abwino pang'ono:
- Nthawi zonse mutsirizitse gulu lanu ndi semicolon. Olemba a HTML ena amakulolani kuti mutumize ma code HTML popanda semicolon yomaliza, koma masamba anu adzakhala osayenera, ndipo ma webusaiti ambiri sangawonetse zigawozo molondola popanda izo.
- Nthawi zonse muziyamba ndi ampersand. Olemba ambiri a webusaiti amakulolani kuchoka ndi "amp;" koma mukawonetsa ampersand yekha mu XHTML, imayambitsa vuto lovomerezeka.
- Yesani masamba anu m'masakatuli ambiri momwe mungathere. Ngati khalidweli ndilofunika kwambiri kuti mumvetse chilemba chanu ndipo simungakhoze kuyesa muzosakaniza / OS omwe makasitomala anu amagwiritsa ntchito, muyenera kupeza njira yowonjezera. Komabe, musanayambe kujambula zithunzi kapena chinthu china, yesani njira imodzi yowunikira osakayikira yomwe ingatsimikizire code yanu mumasakatuli angapo.
