Isu dan cabaran dengan menjajarkan imej dalam Flexbox
Saya telah mengusahakan halaman utama yang saya bangunkan baru-baru ini dan mengalami sedikit kesukaran untuk menjajarkan item saya dalam kotak fleksibel. Kotak flex pertama hendaklah mengandungi tiga (3) imej dan semua imej hendaklah dalam garisan menegak di bawah satu sama lain.
Terdapat pelbagai cara untuk melaksanakan reka letak ini, grid CSS, Flexbox dan reka letak berbilang lajur semuanya berfungsi (dengan cara yang berbeza).
Perkara pertama yang saya cadangkan ialah mengubah suai HTML. Secara semantik, anda nampaknya menunjukkan senarai sifat, yang dengan serta-merta mencadangkan bahawa senarai harus digunakan (sama ada tersusun atau tidak tertib); <figure>
Dengan semakan ini, setelah dibungkus dengan
...), HTML di atas mungkin menjadi seperti ini: <main> 标记（或 <section>、<article>
Unsere Immobilien
PlaceKitten image: 1
PlaceKitten image: 2
PlaceKitten image: 3
PlaceKitten image: 4
PlaceKitten image: 5
PlaceKitten image: 6
Gunakannya dengan reka letak berbilang lajur dan tambahkan ulasan penjelasan dalam CSS:
/* CSS custom properties used to provide common theming
to multiple elements: */

--commonSpacing: 1em;
}
/* a simple CSS reset to remove default margins,
and padding; ensuring all browsers use the
same sizing algorithm for content, and also

*,
::before,
::after {
box-sizing: border-box;
font-family: system-ui;
font-size: 16px;
margin: 0;
padding: 0;
}
/* to emphasise the heading: */
h4 {
font-size: 1.8em;
margin-block: calc(0.5 * var(--commonSpacing));
text-align: center;
}
main {
/* setting the size of the inline axis (width, in English and
Latin languages) to 80 viewport width units, with a minimum
size of 30 root-em units, and a maximum size of 1300 pixels: */
inline-size: clamp(30rem, 80vw, 1300px);
/* centering the element on the inline axis: */
margin-inline: auto;
}
ul {
/* using multi-column layout,

column-count: 2;

list-style-type: none;
/* centering the elements

text-align: center;
}
li {
/* ensuring that the

its contents spread over columns,
leaving unsightly orphans at the
end, or beginning, of a column: */
break-inside: avoid;
/* spacing the elements out: */
margin-block-end: var(--commonSpacing);
}
Ini juga boleh dilakukan menggunakan grid CSS, walaupun nombor dengan grid akan mengalir dari kiri ke kanan dan kemudian dari atas ke bawah:
