This is my code. I am not familiar with css and I don’t know how to do many things. I want to make

This is placed on the same line as

, but it just can't be placed. It's strange.

That iframe I just can’t put it in! ! ! !

The div is block-level elementless. Each div will occupy one line by default, so you can't do that. You can refer to http://www.w3school.com.cn/css/css_positioning_floating.asp

I remember there is a floating element or something, float:left which seems to work but I don’t know how to do it!

You should use several large divs as iframe layout, and then use float to arrange the small divs in the large divs. For example, the left and right structure is two large divs with a width of 2:8; just like iframe That's it

You can use css float to set it

Solution:
.div_left_dh
{
float:left;
}

In this code
#div_iframe{
margin-left: 130px;
width: 100%;
Padding: 0px;
}

Add the one above, float:left;

It works really well.
But I don’t quite understand. My original div_buttom contains two divs, div_left_dh and div_iframe.
I planned to float it inside div_buttom, but why doesn’t it work? Why do I do it in div_left_dh?

Float Left Float Right Float. How do you float the parent layer? In fact, you can understand this as "div_buttom" which is the name of a box. There are two things in the box, one is called "div_left_dh" and the other is called "div_iframe". There is a rule defined in this box. That is, by default, the items in the box can only be stacked upwards. Only if you make one of them float can it coexist with another on the same layer. It's rather rough to say.

The poster can carefully read the description of the float attribute

The float attribute is not inherited unless specified float:inherit

If you float div_buttom left
, it will not affect the floating of child divs (div_left_dh and div_iframe)

but the child div (div_left_dh and div_iframe) is inside div_buttom Ah, it feels a bit messy...

After specifying div_buttom to float left, just float the div_buttom block to the left
But because float does not inherit
div_left_dh in all div_buttom blocks by default, div_iframe still follows the default layout
That is, first div_left_dh block
and then div_iframe block
The display effect is two blocks up and down

It’s generally clearer, thank you!
