Zvakatinakira: CSS-marongerwo

Kana marongerwo peji Kazhinji zvakakosha kuti haashandisi CSS-nzira: somuenzaniso, hwokunyanya chikuru chimwe. Pane zvingaitwa akawanda kuti dambudziko iri, mumwe nomumwe izvo tichikufunga kushandisa chero coder.

Swatanudza chinyorwa hwokunyanya

Kazhinji nokuti kushongedza uchida kuisa mashoko icharwirwa, CSS muchiitiko ichi, kuderedza nguva nokuiswa. Kare izvi zvakaitwa uchishandisa HTML-unhu, asi ikozvino mureza kunodiwa kuti vaenzanise mashoko pamwe wokugadzira pepa. Kusiyana chinogona izvo zvaunoda kuchinja kwokunze padding mu CSS inogara rwezuva pakati anoitwa rimwe chete mutsetse:

• chinyorwa-swatanudza: centre;

pfuma iyi nhaka uye akapfuura kubva mubereki vose vana. Zvinokanganisawo kwete chete rugwaro asiwo vamwe zvinhu. Nokuti chinangwa ichi, dzinofanira lowercase (semuenzaniso, span) kana mutsara-chezvakaipa (chero kutigumbura kuti tsanangurai kuratidza pfuma: misa). Zvapedzisira Ipfungwa inokupai kuti kushandura upamhi uye kukwirira chinhu, zvikuru kusanduka configuration yacho indentation.

mapeji kazhinji swatanudza chizenga kwezvakataurwa chipepa. Izvi pakarepo zvinoita bumbiro remitemo ndonda, sezvo W3C akabvuma swatanudza chizenga usingachashandi. Kurishandisa uri papeji haisi inokurudzirwa.

anyatsonanga misa

Kana uchida kuisa mashoko inogara div pakati, CSS anogona kupa zvikuru hwomutambarakede nzira: kushandiswa kwokunze padding kumucheto. Padding zvinogona kutaurwa sezvo chinogumbura okunze, uye mutsetse-chezvakaipa. Svoysva ukoshi inofanira kuva 0 (hunyambiri padding), uye motokari (otomatiki indentation yakatambarara):

• kumucheto: 0 auto;

Zvino pfungwa iyi kuzivikanwa sezvo zvachose kushanda. Kushandisa kwokunze padding inokupai iwe kugadza inogara pakati: CSS-kumucheto pfuma kunotibvumira kugadzirisa matambudziko akawanda chokuita Positioning chinhu papeji.

Inogara kuruboshwe kana kurudyi kwakapinza misa

Dzimwe nguva CSS-nzira hakurevi inogara pakati, asi zvinokosha kuti kuisa anotevera maviri zvinogumbura, mumwe kubva kurutivi rworuboshwe uye mumwe - kubva kurudyi. Nokuti ichi pane ichiyangarara pfuma, iyo inogona kutora rimwe matatu tsika: kuruboshwe, kurudyi kana hapana. Toti une zvingaenzana nemidhadhadha miviri kuti zvinofanira kuiswa parutivi. Ipapo code sezvinotevera:

• .left {ichiyangarara: kuruboshwe;}
• .right {ichiyangarara: kurudyi}

Kana paine chidhina rechitatu, izvo zvinofanira riri pasi zvidhinha maviri okutanga (semuenzaniso, footer), ipapo zvakafanira kunyoresa zvakajeka inoti:

• .left {ichiyangarara: kuruboshwe;}
• .right {ichiyangarara: kurudyi}
• footer {zvakajeka: vaviri}

Chokwadi kuti zvidhinha pamwe makirasi kurudyi kuwa kubva zvachose aibuda, kureva, zvose zvimwe zvinhu kuteerera chaizvo nokuvapo zvinhu dzichienderana. Property zvakajeka: vose anobvumira footer chinogumbura kana zvimwe inooneka kunokurumidziswa kubva chekubuda masero uye unorambidza wrap (ichiyangarara) vose kuruboshwe nezvakarurama. Saka, muna muenzaniso wedu, footer iri misha pasi.

mira kunangiswa

Pane zviitiko apo kwete zvakakwana kugadza inogara pakati CSS-nzira, unofanirawo kushandura hunyambiri nzvimbo mwana chinhu chinogumbura. Chero mutsetse kana mutsara-chinogumbura chaikosha zvinogona waitsimbirira rokumusoro kana yakaderera unopinza, riri pakati mubereki chinhu kana kuva chinhu zvemasanga nzvimbo. Kakawanda zvinoda inogara pakati anovhara, rinoshandisa kutwasuka-swatanudza chizenga. Ngatitii pane zvingaenzana nemidhadhadha miviri, mumwe nested mukati mumwe. In ichi indoor chikwata - musara-chinogumbura chaikosha (kuratidza: Inline-chezvakaipa). Zvakakodzera swatanudza hunyambiri chinogumbura mwana:

• inogara yokumusoro muganhu - .child {kutwasuka-swatanudza: pamusoro};
• hwakavakirwa - .child {kutwasuka-swatanudza: pakati};
• inogara pasi pamucheto - .child {kutwasuka-swatanudza: bottom};

At misa zvinhu Audio acho-swatanudza, kana kutwasuka-swatanudza haushandi.

Possible nematambudziko dzichienderana dzakabatana

Dzimwe nguva div swatanudza Nhongonya CSS-nzira inogona kukonzera zvishoma dambudziko. Somuenzaniso, apo uchishandisa ichiyangarara: somuenzaniso, kune kutigumbura matatu: .first, .second uye .third. Wechipiri newechitatu kutigumbura vavete yokutanga. An chinhu aine boka rechipiri vasara-dzichienderana, uye yokupedzisira chinogumbura - kurudyi. Pashure tsitsi vaviri zvikanyauka rukova. Kana mubereki chinhu hauna kunorondedzerwa kumusoro (semuenzaniso, 30em), zvichaita kurega ruoko kureba chikamu dzakabatana. Kudzivisa kukanganisa ichi, shandisa "spacer" - chaiyo Unit, iro achiona .second uye .third. CSS-code:

• .second {kuyangarara: kuruboshwe}
• .third {ichiyangarara: kurudyi}
• .clearfix {kukwirira: 0; zvakajeka: vaviri;}

ekunyebera inowanzoshandiswa: pashure, iyo inokupai kudzoka zvidhinha panzvimbo paakasika psevdorasporki (ari muenzaniso iri div pamwe kirasi nhema mukati mudziyo uye unotora munhu .first .left uye .right):

• .left {ichiyangarara: kuruboshwe}
• .right {ichiyangarara: kurudyi}
• .container: pashure {kugutsikana: ''; kuratidza: tafura; zvakajeka: vaviri;}

The pamusoro nzira - rakajairika, kunyange zvazvo pane zvimwe zvakasiyana. Unogona nguva dzose kuwana nyore uye zvikuru yokuita nzira chokusika psevdorasporki nokuongorora.

Chimwe chinetso kazhinji vasangana marongerwo - inogara mutsetse-misa zvinhu. Shure mumwe nomumwe nzvimbo iri awedzera kwaita. Bata zvinobatsira kumahombekombe pfuma, iyo chinorondedzerwa nemashoko akaipa indentation. Pane dzimwe nzira, iyo inoshandiswa zvishoma kakawanda Somuenzaniso, itangezve Sarudza saizi. Panyaya iyi, iyo nzvimbo yacho mubereki chinhu kunonyora Kukura-size: 0. Kana riri mukati inoperera wenyaya, Zvivako edzinza-misa zvinhu madzokera kutsvakwa Schriftgröße. Somuenzaniso, Kukura-size: 1em. Nzira haisi nguva dzose nyore, saka zviri zvikuru inowanzoshandiswa shanduro nechitarisiko varikumahombekombe.

Tsitsi Blocks unokubvumira kusika mapeji akanaka uye dzichipfekeka: mukuru marongerwo uye marongerwo, uye nzvimbo kwenhumbi dziri zvitoro, uye mapikicha ari nzvimbo duku.
