Lavozim

Elementning o'rnini tezda sozlash uchun ushbu stenok yordam dasturlaridan foydalaning.

Lavozim qiymatlari

Tez joylashishni aniqlash darslari mavjud, ammo ular javob bermaydi.

<div class="position-static">...</div>
<div class="position-relative">...</div>
<div class="position-absolute">...</div>
<div class="position-fixed">...</div>
<div class="position-sticky">...</div>

Elementlarni tartibga solish

Elementlarni chekka joylashishni aniqlash vositalari yordamida osongina joylashtiring. Format bu {property}-{position}.

Bu erda mulk quyidagilardan biri hisoblanadi:

  • top- vertikal topholat uchun
  • start- gorizontal leftholat uchun (LTR da)
  • bottom- vertikal bottomholat uchun
  • end- gorizontal rightholat uchun (LTR da)

Bu erda pozitsiya quyidagilardan biri:

  • 0- 0chekka holati uchun
  • 50- 50%chekka holati uchun
  • 100- 100%chekka holati uchun

$position-values( Sass xaritasi oʻzgaruvchisiga yozuvlar qoʻshish orqali koʻproq joylashuv qiymatlarini qoʻshishingiz mumkin .)

<div class="position-relative">
  <div class="position-absolute top-0 start-0"></div>
  <div class="position-absolute top-0 end-0"></div>
  <div class="position-absolute top-50 start-50"></div>
  <div class="position-absolute bottom-50 end-50"></div>
  <div class="position-absolute bottom-0 start-0"></div>
  <div class="position-absolute bottom-0 end-0"></div>
</div>

Markaziy elementlar

Bundan tashqari, siz elementlarni transform yordam klassi bilan markazlashtirishingiz mumkin .translate-middle.

Ushbu klass o'zgarishlarni translateX(-50%)va translateY(-50%)elementga nisbatan qo'llaniladi, ular chekka joylashishni aniqlash yordamchi dasturlari bilan birgalikda elementni mutlaq markazlashtirishga imkon beradi.

<div class="position-relative">
  <div class="position-absolute top-0 start-0 translate-middle"></div>
  <div class="position-absolute top-0 start-50 translate-middle"></div>
  <div class="position-absolute top-0 start-100 translate-middle"></div>
  <div class="position-absolute top-50 start-0 translate-middle"></div>
  <div class="position-absolute top-50 start-50 translate-middle"></div>
  <div class="position-absolute top-50 start-100 translate-middle"></div>
  <div class="position-absolute top-100 start-0 translate-middle"></div>
  <div class="position-absolute top-100 start-50 translate-middle"></div>
  <div class="position-absolute top-100 start-100 translate-middle"></div>
</div>

Sinflarni qo'shish orqali elementlarni faqat gorizontal yoki vertikal yo'nalishda joylashtirish mumkin .translate-middle-x..translate-middle-y

<div class="position-relative">
  <div class="position-absolute top-0 start-0"></div>
  <div class="position-absolute top-0 start-50 translate-middle-x"></div>
  <div class="position-absolute top-0 end-0"></div>
  <div class="position-absolute top-50 start-0 translate-middle-y"></div>
  <div class="position-absolute top-50 start-50 translate-middle"></div>
  <div class="position-absolute top-50 end-0 translate-middle-y"></div>
  <div class="position-absolute bottom-0 start-0"></div>
  <div class="position-absolute bottom-0 start-50 translate-middle-x"></div>
  <div class="position-absolute bottom-0 end-0"></div>
</div>

Sass

Xaritalar

Standart joylashuv yordam dasturi qiymatlari Sass xaritasida e'lon qilinadi, so'ngra utilitalarimizni yaratish uchun ishlatiladi.

$position-values: (
  0: 0,
  50: 50%,
  100: 100%
);

Utilities API

Position utilities bizning yordam dasturlarimiz API da e'lon qilingan scss/_utilities.scss. API yordam dasturlarini qanday ishlatishni bilib oling.
