CSS-da Fleksbokslar bilan ishlash
Bilganingizdek, justify-content xususiyati mavjud,
u elementlarni asosiy o'q bo'yicha joylashtiradi.
Shuningdek, align-items xususiyati ham mavjud, u
elementlarni ko'ndalang o'q bo'yicha joylashtiradi. Keling
uncha oz uning bilan o'ynaymiz.
Faraz qilaylik, bizda bloklar qator bo'yicha joylashgan,
ya'ni ko'ndalang o'q pastga yo'nalgan.
align-items yordamida ushbu bloklarni
markazga joylashtiramiz:
<div class="parent">
<div class="child">1</div>
<div class="child">2</div>
<div class="child">3</div>
</div>
.parent {
display: flex;
flex-direction: row;
align-items: center;
width: 300px;
height: 300px;
border: 1px solid red;
}
.child {
box-sizing: border-box;
width: 100px;
height: 100px;
border: 1px solid green;
}
:
Keling endi ko'proq bloklar qo'shamiz,
flex-wrap yordamida ko'p qatorlilikni qo'shamiz,
ota-onaning balandligini 300px dan
500px ga oshiramiz va align-items
qanday ishlashini bu ko'p qatorli holatda ko'rib chiqamiz:
<div class="parent">
<div class="child">1</div>
<div class="child">2</div>
<div class="child">3</div>
<div class="child">4</div>
<div class="child">5</div>
<div class="child">6</div>
<div class="child">7</div>
<div class="child">8</div>
<div class="child">9</div>
</div>
.parent {
display: flex;
flex-direction: row;
align-items: center;
flex-wrap: wrap;
width: 300px;
height: 500px;
border: 1px solid red;
}
.child {
box-sizing: border-box;
width: 100px;
height: 100px;
border: 1px solid green;
}
:
Ko'rib turganimizdek, markazlashtirish unchalik yaxshi emas. Go'yo har bir qator o'ziga ajratilgan joyda o'zi markazga joylashayotgandek. Keling, barcha qatorlar birlashgan holda ota-onaning markaziga joylashishi uchun qilamiz.
Buning uchun align-content xususiyatidan foydalanish kerak,
u ko'p qatorli matn uchun mo'ljallangan.
Kodimizni qayta yozamiz:
<div class="parent">
<div class="child">1</div>
<div class="child">2</div>
<div class="child">3</div>
<div class="child">4</div>
<div class="child">5</div>
<div class="child">6</div>
<div class="child">7</div>
<div class="child">8</div>
<div class="child">9</div>
</div>
.parent {
display: flex;
flex-direction: row;
align-content: center;
flex-wrap: wrap;
width: 300px;
height: 500px;
border: 1px solid red;
}
.child {
box-sizing: border-box;
width: 100px;
height: 100px;
border: 1px solid green;
}
:
align-content xususiyati align-items
kabi qiymatlarni qabul qiladi.
space-between qiymati
Keling, misol uchun space-between qiymatini ko'rib chiqaylik.
Ota-ona balandligini 320px ga sozlaymiz. Bizda uchta
qator borligi sababli, va shuning uchun qatorlar orasida
ikki masofa bo'ladi, bu masofalarning har biri
10px ga teng bo'ladi:
<div class="parent">
<div class="child">1</div>
<div class="child">2</div>
<div class="child">3</div>
<div class="child">4</div>
<div class="child">5</div>
<div class="child">6</div>
<div class="child">7</div>
<div class="child">8</div>
<div class="child">9</div>
</div>
.parent {
display: flex;
flex-direction: row;
align-content: space-between;
flex-wrap: wrap;
width: 300px;
height: 320px;
border: 1px solid red;
}
.child {
box-sizing: border-box;
width: 100px;
height: 100px;
border: 1px solid green;
}
:
stretch qiymati
Keling, stretch qiymatini sinab ko'ramiz.
Buning uchun avlodlarning balandligini olib tashlaymiz, ota-onaning
balandligini esa 600px ga aniqroq ta'sir ko'rsatish uchun o'rnatamiz.
<div class="parent">
<div class="child">1</div>
<div class="child">2</div>
<div class="child">3</div>
<div class="child">4</div>
<div class="child">5</div>
<div class="child">6</div>
<div class="child">7</div>
<div class="child">8</div>
<div class="child">9</div>
</div>
.parent {
display: flex;
flex-direction: row;
align-content: stretch;
flex-wrap: wrap;
width: 300px;
height: 600px;
border: 1px solid red;
}
.child {
box-sizing: border-box;
width: 100px;
border: 1px solid green;
}
:
align-content uchun stretch qiymati standart qiymat hisoblanadi.
Agar biz avlodlarning balandligini butunlay olib tashlasak,
align-content xususiyatini olib tashlasak,
lekin ota-onaning balandligi va flex-wrap ni qoldirsak
- hammasi shunday ishlaydi:
<div class="parent">
<div class="child">1</div>
<div class="child">2</div>
<div class="child">3</div>
<div class="child">4</div>
<div class="child">5</div>
<div class="child">6</div>
<div class="child">7</div>
<div class="child">8</div>
<div class="child">9</div>
</div>
.parent {
display: flex;
flex-direction: row;
flex-wrap: wrap;
width: 300px;
height: 600px;
border: 1px solid red;
}
.child {
box-sizing: border-box;
width: 100px;
border: 1px solid green;
}
:
Agar flex-wrap ni ham olib tashlasak
- hammasi bir qatorli bo'lib qoladi:
<div class="parent">
<div class="child">1</div>
<div class="child">2</div>
<div class="child">3</div>
<div class="child">4</div>
<div class="child">5</div>
<div class="child">6</div>
<div class="child">7</div>
<div class="child">8</div>
<div class="child">9</div>
</div>
.parent {
display: flex;
flex-direction: row;
width: 300px;

border: 1px solid red;
}
.child {

width: 100px;

}
