Mengenai Helaian Rujukan Bootstrap
Helaian rujukan Bootstrap ini menyasarkan Bootstrap 5.3 dan mengumpulkan nama kelas yang anda taip sepanjang hari: grid dan susun atur, utiliti jarak, tipografi, warna dan latar belakang, utiliti flex, paparan dan kedudukan, saiz dan sempadan, butang, borang, komponen dan pembantu.
Produktiviti Bootstrap kebanyakannya bergantung pada perbendaharaan kata — mengetahui bahawa sesuatu kelas wujud dan bagaimana bentuk sedar-breakpoint-nya kelihatan. Setiap baris menunjukkan satu kelas atau serpihan markup dengan penerangan satu baris, jadi jawapan kepada "apa nama utiliti tadi?" hanya sejauh satu carian, bukan penerokaan dokumentasi.
Helaian ini percuma dan berjalan sepenuhnya di sisi klien. Tapis kelas secara langsung dengan kotak carian, lompat antara bahagian daripada kandungan lekat, salin mana-mana serpihan dengan satu klik dan cetak halaman sebagai rujukan semasa anda membina susun atur.
Cara menggunakan Helaian Rujukan Bootstrap
- Imbas bahagian-bahagian, dari Grid & susun atur dan Utiliti jarak hingga Komponen dan Pembantu & lain-lain.
- Cari utiliti seperti gap, rounded atau d-flex untuk menapis helaian dengan segera.
- Lompat ke bahagian seperti Utiliti flex atau Borang melalui bar sisi lekat.
- Klik satu kelas atau serpihan, atau ikon salinnya, untuk menyalinnya ke dalam markup anda.
- Cetak helaian ini sebagai rujukan nama kelas di sebelah editor anda.
