Qalisa kabusha

Qalisa kabusha, iqoqo lezinguquko ze-CSS zesici esithile efayeleni elilodwa, qala i-Bootstrap ukuze unikeze isisekelo esihle, esingaguquki, nesilula ongakhela phezu kwaso.

Kuleli khasi

Indlela

Qalisa kabusha yakhela phezu kwe-Nomalise, ihlinzeka ngezinto eziningi ze-HTML ezinezitayela ezicatshangelwe imibono ethile usebenzisa izikhethi zezinto kuphela. Isitayela esengeziwe senziwa kuphela ngamakilasi. Isibonelo, siqalisa kabusha ezinye <table>izitayela ukuze sithole isisekelo esilula futhi kamuva sinikeze .table, .table-bordered, nokuningi.

Nansi imihlahlandlela yethu nezizathu zokukhetha ukuthi yini ongayibhala ekuqaliseni kabusha:

Buyekeza amanani amisiwe esiphequluli ukuze uwasebenzise u rem-s esikhundleni sika- ems ukuze uthole izikhala zezingxenye ezingakala.
Gwema margin-top. Amamajini aqondile angawa, aveze imiphumela engalindelekile. Okubaluleke nakakhulu, isiqondiso esisodwa marginsiyimodeli yengqondo elula.
Ukuze kube lula ukukala kuwo wonke amasayizi wedivayisi, ama-elementi ebhulokhi kufanele asebenzise remu-s ku- margins.
Gcina izimemezelo fontzezakhiwo ezihlobene zibe zincane, usebenzisa inheritnoma nini lapho kunokwenzeka.

Okuzenzakalelayo kwekhasi

Ama- elementi <html>kanye nama - <body>elementi abuyekeziwe ukuze anikeze okuzenzakalelayo okungcono ekhasini lonke. Ngokuqondile:

I box-sizing-elementi isethwe emhlabeni wonke kuwo wonke ama-elementi—kuhlanganise *::beforefuthi *::after, kuya ku- border-box. Lokhu kuqinisekisa ukuthi ububanzi obushiwo be-elementi abulokothi budlulwe ngenxa yokupheda noma umngcele.
- Asikho isisekelo font-sizeesimenyezelwe ku- <html>, kodwa 16pxkuyacatshangelwa (okuzenzakalelayo kwesiphequluli). font-size: 1remisetshenziswa kuhlelo <body>lokukala uhlobo oluphendulayo olulula ngemibuzo yemidiya ngenkathi ihlonishwa izintandokazi zabasebenzisi futhi iqinisekisa indlela efinyeleleka kakhudlwana. Lokhu okumisiwe kwesiphequluli kungakhishwa ngokulungisa $font-size-rootokuguquguqukayo.
I-The <body>futhi isetha umhlaba wonke font-family, font-weight, line-height, kanye color. Lokhu kuzuzwa njengefa kamuva ezinye izici zefomu ukuvimbela ukungqubuzana kwefonti.
Ukuze uvikeleke, i- inesimemezelo <body>esimisiwe background-color, esishintshashintshayo sithi #fff.

Isitaki sefonti yomdabu

I-Bootstrap isebenzisa "isitaki sefonti yomdabu" noma "isitaki sefonti yesistimu" ukuze kunikezwe umbhalo ophelele kuwo wonke amadivayisi ne-OS. Lawa mafonti esistimu aklanywe ngokukhethekile kucatshangelwa amadivayisi anamuhla, ngokunikezwa okuthuthukisiwe ezikrinini, ukusekelwa kwefonti eguquguqukayo, nokuningi. Funda kabanzi mayelana nezitaki zefonti zomdabu kulesi sihloko se - Smashing Magazine .

$font-family-sans-serif:

Qaphela ukuthi ngenxa yokuthi isitaki sefonti sihlanganisa amafonti e-emoji, izinhlamvu eziningi ezivamile zophawu/i-dingbat zizonikezwa njengama-pictograph anemibala eminingi. Ukubukeka kwazo kuzohluka, kuye ngesitayela esisetshenziswe kufonti ye-emoji yomdabu yesiphequluli/inkundla, futhi ngeke zithintwe yinoma yiziphi colorizitayela ze-CSS.

Lokhu font-familykusetshenziselwa <body>futhi kuzuzwe njengefa ngokuzenzakalelayo emhlabeni wonke kuyo yonke i-Bootstrap. Ukuze ushintshe okomhlaba font-family, buyekeza $font-family-baseuphinde uhlanganise i-Bootstrap.

Izihloko nezigaba

Zonke izakhi zesihloko—isb, <h1>—futhi zisethwa <p>kabusha ukuze margin-topzisuswe. Izihloko margin-bottom: .5remzengeziwe kanye nezigaba margin-bottom: 1remukuze kube lula ukuhlukanisa.

Isihloko	Isibonelo
`<h1></h1>`	h1. Isihloko se-Bootstrap
`<h2></h2>`	h2. Isihloko se-Bootstrap
`<h3></h3>`	h3. Isihloko se-Bootstrap
`<h4></h4>`	h4. Isihloko se-Bootstrap
`<h5></h5>`	h5. Isihloko se-Bootstrap
`<h6></h6>`	h6. Isihloko se-Bootstrap

Uhlu

Zonke izinhlu— <ul>, <ol>, kanye <dl>— zisusiwe margin-topfuthi a margin-bottom: 1rem. Uhlu olufakiwe alunazo margin-bottom. Sisethe kabusha i- padding-lefton <ul>kanye nama - <ol>elementi.

Zonke izinhlu zinemajini yazo ephezulu isusiwe
Futhi umkhawulo wabo ophansi ujwayelekile
Uhlu olufakwe kusidleke alunayo imajini engezansi
- Ngale ndlela banokubukeka okulinganayo
- Ikakhulukazi uma kulandelwa ezinye izinto zohlu
I-padding yesokunxele nayo isethwe kabusha

Nalu uhlu olu-odwe
Ngezinto ezimbalwa zohlu
Inokubukeka okufanayo jikelele
Njengohlu lwangaphambilini olunga-odwe

Ukuze uthole isitayela esilula, isigaba esicacile, nezikhala ezingcono, izinhlu zezincazelo zibuyekeziwe margins. <dd>s setha kabusha margin-leftfuthi 0wengeze margin-bottom: .5rem. <dt>s banesibindi .

Uhlu lwezincazelo: Uhlu lwezincazelo luphelele ekuchazeni amagama.
Ithemu: Incazelo yetemu.; Incazelo yesibili yetemu elifanayo.
Elinye igama: Incazelo yaleli elinye igama.

Ikhodi esemgqeni

Goqa amazwibela ekhodi nge- <code>. Qiniseka ukuthi ubalekela kubakaki be-engeli ye-HTML.

Isibonelo, <section>kufanele isongwe njenge-inline.

For example, <code>&lt;section&gt;</code> should be wrapped as inline.

Amabhulokhi ekhodi

Sebenzisa <pre>u-s emigqeni eminingi yekhodi. Nakulokhu, qiniseka ukuthi ubalekela noma yibaphi abakaki be-engeli kukhodi ukuze unikezwe ngendlela efanele. I- <pre>elementi isethwe kabusha ukuze kukhishwe margin-topfuthi kusetshenziswe remamayunithi ayo margin-bottom.

<p>Sample text here...</p>
<p>And another line of sample text here...</p>

<pre><code>&lt;p&gt;Sample text here...&lt;/p&gt;
&lt;p&gt;And another line of sample text here...&lt;/p&gt;
</code></pre>

Okuguquguqukayo

Ukuze ubonise okuguquguqukayo sebenzisa <var>ithegi.

y = m x + b

<var>y</var> = <var>m</var><var>x</var> + <var>b</var>

Okokufaka komsebenzisi

Sebenzisa <kbd>ukukhombisa okokufaka okuvamise ukufakwa ngekhibhodi.

Ukuze ushintshe uhla lwemibhalo, thayipha cdulandelwe yigama lohla lwemibhalo.
Ukuze uhlele izilungiselelo, cindezela ctrl + ,

To switch directories, type <kbd>cd</kbd> followed by the name of the directory.<br>
To edit settings, press <kbd><kbd>ctrl</kbd> + <kbd>,</kbd></kbd>

Okukhiphayo okuyisampula

Ukuze ubonise ukuphuma kwesampula kuhlelo sebenzisa <samp>ithegi.

Lo mbhalo uhloselwe ukuthi uthathwe njengesampula ephuma ohlelweni lwekhompyutha.

<samp>This text is meant to be treated as sample output from a computer program.</samp>

Amathebula

Amathebula alungiswa kancane ukuze abe yisitayela <caption>sika-s, agoqe imingcele, futhi aqinisekise ukuhambisana text-alignkulo lonke. Izinguquko ezengeziwe zemingcele, iziphedi, nokunye kuza nekilasi ..table

Leli yithebula eliyisibonelo, futhi leli yigama-ncazo elichaza okuqukethwe.
Isihloko sethebula	Isihloko sethebula	Isihloko sethebula	Isihloko sethebula

Amafomu

Izakhi zefomu ezahlukahlukene ziqaliswe kabusha ngezitayela zesisekelo ezilula. Nazi ezinye zezinguquko eziphawuleka kakhulu:

<fieldset>s ayinayo imingcele, i-padding, noma imajini ukuze isetshenziswe kalula njengama-wrappers okokufaka ngakunye noma amaqembu okokufaka.
<legend>s, njengama-fieldsets, aphinde ashintshwa ukuze aboniswe njengesihloko sezinhlobo.
<label>s isethwe display: inline-blockukuze ivumele marginukusetshenziswa.
<input>s, <select>s, <textarea>s, kanye no- <button>s abhekiswa kakhulu ngokuthi Normalize, kodwa Qalisa kabusha kususa marginfuthi namasethi line-height: inherit, futhi.
<textarea>ama-s alungiswa ukuze akwazi ukukhulisa usayizi oqondile kuphela njengoba usayizi ovundlile ngokuvamile "uphula" ukwakheka kwekhasi.
<button>s kanye <input>nezakhi zenkinobho zinanini cursor: pointerlapho :not(:disabled).

Lezi zinguquko, nokunye okwengeziwe, kuboniswa ngezansi.

Izikhombisi ezinkinobho

Ukuqalisa kabusha kufaka phakathi isithuthukisi role="button"sokushintsha ikhesa ezenzakalelayo ibe yi- pointer. Engeza lesi sibaluli kuma-elementi ukusiza ukukhombisa ukuthi ama-elementi ayasebenzisana. Le ndima ayidingekile kuma- elementi, athola ushintsho <button>lwawo .cursor

HTML5 `[hidden]`isibaluli

I- HTML5 yengeza isibaluli esisha somhlaba wonke esiqanjwe ngokuthi[hidden] , esiqanjwe ngokuthi display: nonengokuzenzakalela. Ukuboleka umbono ku- PureCSS , sithuthukisa kulokhu okuzenzakalelayo ngokwenza [hidden] { display: none !important; }ukusiza ukuvimbela displayukuthi ingaphumi ngephutha.

<input type="text" hidden>

ukungahambisani kwe-jQuery

[hidden]ayihambisani ne-jQuery $(...).hide()kanye $(...).show()nezindlela. Ngakho-ke, okwamanje asikhuthazi kakhulu [hidden]phezu kwamanye amasu displayokuphatha ama-elementi.

Ukuze nje uguqule ukubonakala kwento ethile, okusho ukuthi displayayilungiswanga futhi isici sisengaphazamisa ukuhamba kwedokhumenti, sebenzisa isigaba.invisible esikhundleni salokho .
