Ajratuvchilar

::beforeAjratuvchilar CSS-ga va orqali avtomatik ravishda qo'shiladi content. Ular mahalliy CSS xususiy xususiyatini o'zgartirish --bs-breadcrumb-divideryoki $breadcrumb-dividerSass o'zgaruvchisi orqali va $breadcrumb-divider-flippedkerak bo'lganda uning RTL hamkasbi uchun o'zgartirilishi mumkin. Biz Sass o'zgaruvchimizga sukut bo'yicha o'rnatamiz, u maxsus xususiyatga zaxira sifatida o'rnatiladi. Shunday qilib, siz istalgan vaqtda CSS-ni qayta kompilyatsiya qilmasdan bekor qilishingiz mumkin bo'lgan global ajratgichga ega bo'lasiz.

html

<nav style="--bs-breadcrumb-divider: '>';" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

Sass orqali o'zgartirilganda, kotirovka funktsiyasi satr atrofida tirnoqlarni yaratish uchun talab qilinadi. Misol uchun, >ajratuvchi sifatida foydalanib, buni ishlatishingiz mumkin:

$breadcrumb-divider: quote(">");

Bundan tashqari, o'rnatilgan SVG belgisidan foydalanish mumkin . Uni CSS maxsus xususiyatimiz orqali qo'llang yoki Sass o'zgaruvchisidan foydalaning.

O'rnatilgan SVG dan foydalanish

SVG-ni ma'lumotlar URI sifatida kiritish URL bir nechta belgilardan qochishni talab qiladi, ayniqsa <, >va #. Shuning uchun $breadcrumb-dividero'zgaruvchi bizning escape-svg()Sass funksiyamiz orqali uzatiladi . CSS-ning maxsus xususiyatidan foydalanganda, SVG-dan mustaqil ravishda URL-dan qochishingiz kerak. Nimadan qochish kerakligi haqida batafsil ma'lumot olish uchun Kevin Weberning CodePen-dagi tushuntirishlarini o'qing .

html

<nav style="--bs-breadcrumb-divider: url(&#34;data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='%236c757d'/%3E%3C/svg%3E&#34;);" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

$breadcrumb-divider: url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' width='8' height='8'><path d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='#{$breadcrumb-divider-color}'/></svg>");

Shuningdek, siz ajratuvchi sozlamasini olib tashlashingiz mumkin --bs-breadcrumb-divider: '';(CSS maxsus xususiyatlaridagi boʻsh satrlar qiymat sifatida hisoblanadi) yoki Sass oʻzgaruvchisini ga oʻrnatishingiz mumkin $breadcrumb-divider: none;.

html

<nav style="--bs-breadcrumb-divider: '';" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

$breadcrumb-divider: none;

Foydalanish imkoniyati

aria-label="breadcrumb"Non parchalari navigatsiyani ta'minlaganligi sababli, elementda taqdim etilgan navigatsiya turini tavsiflash kabi mazmunli yorliqni qo'shish <nav>, shuningdek aria-current="page", joriy sahifani ifodalash uchun to'plamning oxirgi elementiga belgi qo'yish yaxshi bo'ladi.
