RTL cov piv txwv

Pib nrog ib qho ntawm peb ntau tus qauv RTL .

Mus kom ze

Peb txoj hauv kev los tsim RTL kev txhawb nqa rau hauv Bootstrap los nrog ob qhov kev txiav txim siab tseem ceeb uas cuam tshuam li cas peb sau thiab siv peb CSS:

  1. Ua ntej, peb txiav txim siab los tsim nws nrog RTLCSS qhov project. Qhov no muab peb qee qhov muaj zog rau kev tswj hwm kev hloov pauv thiab overrides thaum tsiv ntawm LTR rau RTL. Nws kuj tso cai rau peb tsim ob versions ntawm Bootstrap los ntawm ib tug codebase.

  2. Qhov thib ob, peb tau hloov npe rau ib qho kev qhia ntawm cov chav kawm coj los siv txoj hauv kev kom muaj txiaj ntsig zoo. Feem ntau ntawm koj twb tau cuam tshuam nrog cov khoom muaj txiaj ntsig ua tsaug rau peb cov khoom siv hluav taws xob flex - lawv hloov cov kev taw qhia cov khoom nyiam leftthiab rightnyiam startthiab end. Qhov ntawd ua rau cov npe thiab cov nqi tsim nyog rau LTR thiab RTL yam tsis muaj nyiaj siv ua haujlwm.

Piv txwv li, siv .ml-3rau margin-left, siv .ms-3.

Ua hauj lwm nrog RTL, los ntawm peb qhov chaw Sass los yog muab tso ua ke CSS, yuav tsum tsis txhob ntau txawv ntawm peb LTR default ho.

Customize los ntawm qhov chaw

Thaum nws los txog rau customization , txoj kev nyiam yog coj kom zoo dua ntawm qhov sib txawv, daim duab qhia chaw, thiab mixins. Txoj hauv kev no ua haujlwm zoo ib yam rau RTL, txawm tias nws tau ua tiav los ntawm cov ntaub ntawv muab tso ua ke, ua tsaug rau RTLCSS ua haujlwm li cas .

Kev cai RTL tus nqi

Siv RTLCSS cov lus qhia tus nqi , koj tuaj yeem ua qhov sib txawv ntawm cov txiaj ntsig sib txawv rau RTL. Piv txwv li, txhawm rau txo qhov hnyav rau $font-weight-boldthoob plaws hauv codebase, koj tuaj yeem siv cov /*rtl: {value}*/syntax:

$font-weight-bold: 700 #{/* rtl:600 */} !default;

Uas yuav tso tawm rau cov hauv qab no rau peb lub neej ntawd CSS thiab RTL CSS:

/* bootstrap.css */
dt {
  font-weight: 700 /* rtl:600 */;
}

/* bootstrap.rtl.css */
dt {
  font-weight: 600;
}

Txhawm rau hloov los ntawm Pan-European rau tsev neeg Arabic, koj yuav tsum tau siv /*rtl:insert: {value}*/hauv koj pawg font los hloov cov npe ntawm tsev neeg font.

Piv txwv li, hloov los ntawm Helvetica Neue WebfontLTR Helvetica Neue Arabicrau RTL, koj tus lej Sass zoo li no:

$font-family-sans-serif:
  Helvetica Neue #{"/* rtl:insert:Arabic */"},
  // Cross-platform generic font family (default user interface font)
  system-ui,
  // Safari for macOS and iOS (San Francisco)
  -apple-system,

  "autoRename": true,
  "stringMap":[ {
    "name": "ltr-rtl",
    "priority": 100,
    "search": ["ltr"],

      "ignoreCase": false
    }
  } ]
} */
.ltr {
  @import "../node_modules/bootstrap/scss/bootstrap";
}
/*rtl:end:options*/
