CSS
Ntiaj teb no CSS teeb tsa, cov ntsiab lus HTML tseem ceeb styled thiab txhim kho nrog cov chav kawm txuas ntxiv, thiab cov kab sib chaws siab heev.
Txheej txheem cej luam
Tau txais qhov qis qis ntawm cov khoom tseem ceeb ntawm Bootstrap cov txheej txheem, suav nrog peb txoj hauv kev kom zoo dua, nrawm dua, txhim kho lub vev xaib kom muaj zog.
HTML5 doctype
Bootstrap ua rau siv qee cov ntsiab lus HTML thiab CSS cov khoom uas yuav tsum tau siv HTML5 doctype. suav nrog nws thaum pib ntawm tag nrho koj cov haujlwm.
<!DOCTYPE html>
<html lang="en">
...
</html>Mobile ua ntej
Nrog Bootstrap 2, peb ntxiv cov kev xaiv mobile tus phooj ywg zoo rau qhov tseem ceeb ntawm lub moj khaum. Nrog Bootstrap 3, peb tau rov sau qhov project kom ua tus phooj ywg mobile txij thaum pib. Es tsis txhob ntxiv rau cov kev xaiv mobile, lawv tau ci rau hauv qhov tseem ceeb. Qhov tseeb, Bootstrap yog mobile ua ntej . Cov qauv txawb thawj zaug tuaj yeem pom thoob plaws hauv lub tsev qiv ntawv tag nrho tsis yog hauv cov ntaub ntawv cais.
Txhawm rau kom ua tiav qhov zoo thiab kov zooming, ntxiv qhov pom qhov pom meta tag rau koj <head>.
<meta name="viewport" content="width=device-width, initial-scale=1">Koj tuaj yeem lov tes taw lub peev xwm zooming ntawm cov khoom siv txawb los ntawm kev ntxiv user-scalable=norau qhov pom pom meta tag. Qhov no disables zooming, txhais tau hais tias cov neeg siv tsuas muaj peev xwm mus scroll, thiab ua rau koj qhov chaw zoo li me ntsis ntau dua li ib txwm daim ntawv thov. Zuag qhia tag nrho, peb tsis pom zoo qhov no rau txhua qhov chaw, yog li siv ceev faj!
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">Typography thiab txuas
Bootstrap teeb tsa lub ntiaj teb cov zaub, typography, thiab txuas cov qauv. Tshwj xeeb, peb:
- Teem
background-color: #fff;rau ntawmbody - Siv cov
@font-family-base,@font-size-base, thiab@line-height-basecov cwj pwm ua peb lub hauv paus typographic - Teem lub ntiaj teb txuas xim ntawm
@link-colorthiab siv qhov txuas hauv qab tsuas yog rau:hover
Cov style no tuaj yeem pom hauv scaffolding.less.
Normalize.css
Rau kev txhim kho tus ntoo khaub lig-browser rendering, peb siv Normalize.css , ib qhov project los ntawm Nicolas Gallagher thiab Jonathan Neal .
Ntim
Bootstrap yuav tsum muaj cov khoom siv los qhwv cov ntsiab lus ntawm qhov chaw thiab tsev peb cov kab sib chaws. Koj tuaj yeem xaiv ib qho ntawm ob lub thawv los siv hauv koj cov haujlwm. Nco ntsoov tias, vim paddingthiab ntau dua, ob lub thawv tsis yog zesable.
Siv .containerrau lub teb ruaj ruaj ntim ntim.
<div class="container">
...
</div>Siv .container-fluidrau lub thawv dav dav, hla tag nrho qhov dav ntawm koj qhov chaw saib.
<div class="container-fluid">
...
</div>Daim phiaj system
Bootstrap suav nrog cov lus teb, mobile thawj cov kab sib chaws ua kua dej uas tsim nyog teev txog 12 kab raws li lub cuab yeej lossis qhov chaw saib qhov loj tuaj. Nws suav nrog cov chav kawm ua ntej rau kev xaiv layout yooj yim, nrog rau cov mixins muaj zog rau kev tsim ntau qhov kev sib txuas lus .
Taw qhia
Grid systems yog siv los tsim cov nplooj ntawv layouts los ntawm cov kab thiab kab uas nyob hauv koj cov ntsiab lus. Nov yog yuav ua li cas Bootstrap grid system ua haujlwm:
- Cov kab yuav tsum tau muab tso rau hauv ib qho
.container(taw-dav) lossis.container-fluid(tag nrho-dav) rau kev sib dhos kom zoo thiab padding. - Siv kab los tsim cov kab kab rov tav ntawm kab.
- Cov ntsiab lus yuav tsum tau muab tso rau hauv kab, thiab tsuas yog kab yuav yog cov menyuam yaus ntawm kab.
- Cov chav kawm ntawv predefined grid zoo li
.rowthiab.col-xs-4muaj rau kev ua cov phiaj xwm sai sai. Tsawg mixins kuj tuaj yeem siv rau ntau qhov layouts semantic. - Kem tsim gutters (nruab nrab ntawm kab lus) ntawm
padding. Qhov padding yog offset nyob rau hauv kab rau thawj thiab kawg kem ntawm qhov tsis zoo margin ntawm.rows. - Cov npoo tsis zoo yog vim li cas cov piv txwv hauv qab no yog outdented. Nws yog li ntawd cov ntsiab lus nyob rau hauv kab sib chaws yog lined nrog cov ntsiab lus uas tsis yog kab sib chaws.
- Daim phiaj kab yog tsim los ntawm kev qhia tus naj npawb ntawm kaum ob kab uas koj xav kom ncua. Piv txwv li, peb kab sib npaug yuav siv peb
.col-xs-4. - Yog tias ntau tshaj 12 kab tau muab tso rau hauv ib kab, txhua pawg ntawm kab ntxiv yuav, raws li ib chav tsev, qhwv rau ib kab tshiab.
- Cov chav kawm kab sib chaws siv rau cov khoom siv nrog qhov dav dav dav dua lossis sib npaug ntawm qhov sib npaug ntawm qhov ntau thiab tsawg, thiab hla cov chav kawm ntawv phiaj xwm ntawm cov khoom siv me me. Yog li ntawd, piv txwv li siv ib
.col-md-*chav kawm rau ib lub caij yuav tsis tsuas yog cuam tshuam rau nws cov styling ntawm cov khoom siv nruab nrab tab sis kuj ntawm cov khoom siv loj yog tias tsis muaj.col-lg-*chav kawm.
Saib rau cov piv txwv rau kev siv cov ntsiab cai no rau koj cov cai.
Media lus nug
Peb siv cov lus nug hauv qab no hauv peb cov ntaub ntawv tsawg los tsim cov ntsiab lus tseem ceeb hauv peb cov kab sib chaws.
/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */
/* Small devices (tablets, 768px and up) */
@media (min-width: @screen-sm-min) { ... }
/* Medium devices (desktops, 992px and up) */
@media (min-width: @screen-md-min) { ... }
/* Large devices (large desktops, 1200px and up) */
@media (min-width: @screen-lg-min) { ... }Peb qee zaus nthuav dav ntawm cov lus nug xov xwm no kom suav max-widthnrog txwv CSS rau cov khoom siv nqaim.

Siv ib txheej ntawm .col-md-*kab sib chaws, koj tuaj yeem tsim cov kab sib chaws yooj yim uas pib tawm ntawm cov khoom siv txawb thiab cov ntsiav tshuaj (qhov ntxiv me me rau me me) ua ntej ua kab rov tav ntawm desktop (nruab nrab) cov khoom siv. Muab kab kab kab rau hauv ib qho twg .row.

Ntxiv rau cov chav kawm prebuilt grids rau cov layouts ceev, Bootstrap suav nrog Less variables thiab mixins kom sai tsim koj tus kheej yooj yim, semantic layouts.
Hloov pauv
Cov kev sib txawv txiav txim seb tus naj npawb ntawm kab, qhov dav ntawm lub qhov dej, thiab cov lus nug xov xwm ntawm qhov uas yuav pib cov kab ke. Peb siv cov no los tsim cov chav kawm ntawv teev tseg ua ntej sau tseg saum toj no, nrog rau cov kev cai mixins teev hauv qab no.

Mixins yog siv ua ke nrog cov kab sib chaws sib txawv los tsim cov CSS semantic rau ib tus kab sib chaws.

}Gradints
Yooj yim tig ob xim rau hauv ib qho gradient tom qab. Tau txais kev tshaj lij thiab teeb tsa kev taw qhia, siv peb xim, lossis siv qhov radial gradient. Nrog ib tug mixin koj tau txais tag nrho cov prefixed syntaxes koj yuav xav tau.
#gradient > .vertical(#333; #000);
#gradient > .horizontal(#333; #000);
#gradient > .radial(#333; #000);Koj tuaj yeem hais qhia lub kaum sab xis ntawm tus qauv ob-xim, linear gradient:

}Siv Sass
Thaum Bootstrap yog tsim los ntawm Tsawg, nws kuj muaj qhov chaw nres nkoj Sass . Peb tuav nws hauv ib qho chaw khaws cia GitHub cais thiab tuav cov kev hloov tshiab nrog tsab ntawv hloov dua siab tshiab.
Dab tsi suav nrog
Txij li thaum qhov chaw nres nkoj Sass muaj ib qho repo cais thiab ua hauj lwm rau cov neeg tuaj saib sib txawv me ntsis, cov ntsiab lus ntawm qhov project txawv heev los ntawm lub ntsiab Bootstrap project. Qhov no ua kom qhov chaw nres nkoj Sass yog sib xws nrog ntau Sass-based systems li sai tau.
