مع floatالخاصية ، من السهل تعويم مربعات المحتوى جنبًا إلى جنب:
مثال
* {
box-sizing: border-box;
}
.box {
float: left;
width: 33.33%; /* three
boxes (use 25% for four, and 50% for two, etc) */
padding:
50px; /* if you want space between the images */
}
ما هو حجم الصندوق؟
يمكنك بسهولة إنشاء ثلاثة صناديق عائمة جنبًا إلى جنب. ومع ذلك ، عندما تضيف شيئًا يوسع عرض كل مربع (مثل الحشو أو الحدود) ، فإن المربع سوف ينكسر. تسمح box-sizingلنا الخاصية بتضمين المساحة المتروكة والحد في العرض الكلي (والارتفاع) للمربع ، مع التأكد من بقاء الحشوة داخل الصندوق وعدم كسرها.

الصور جنبًا إلى جنب
يمكن أيضًا استخدام شبكة المربعات لعرض الصور جنبًا إلى جنب:
مثال
.img-container {
float: left;
width: 33.33%; /* three
containers (use 25% for four, and 50% for two, etc) */
padding:
5px; /* if you want space between the images */
}
مربعات متساوية الارتفاع
In the previous example, you learned how to float boxes side by side with an equal width. However, it is not easy to create floating boxes with equal heights. A quick fix however, is to set a fixed height, like in the example below:
Box 1
Some content, some content, some content
Box 2
Some content, some content, some content
Some content, some content, some content
Some content, some content, some content
Example
.box {
height: 500px;
}
However, this is not very flexible. It is ok if you can guarantee that the boxes will always have the same amount of content in them. But many times, the content is not the same. If you try the example above on a mobile phone, you will see that the second box's content will be displayed outside of the box. This is where CSS3 Flexbox comes in handy - as it can automatically stretch boxes to be as long as the longest box:

Navigation Menu
You can also use float with a list of hyperlinks to create a horizontal menu:

Web Layout Example
It is also common to do entire web layouts using the float property:
Example
.header, .footer {
background-color: grey;
color: white;
padding: 15px;
}
.column {
float: left;
padding: 15px;
}
.clearfix::after {
content:
"";
clear: both;
display: table;
}
.menu {
width: 25%;
}
.content {
width: 75%;
}
