Reply to the discussion (solution)

Your div id=bbb The height and width automatically adapt, but the excess part of the div with id=bbb will have horizontal and vertical scroll bars. This is difficult to achieve. You can make aaa have scroll bars after exceeding the height of aaa

Change the div id=bbb height :100% to height:70px is the effect I want

But this is hard-coded and will not automatically change according to aaaa
aaaa

Is it impossible to call a master?

#bbb{height:100%;width:100%;overflow:scroll;}

The two brothers upstairs, have you run the html code? It doesn’t work.

The row height and column width of your table should be Use percentage settings, otherwise the table will adapt to the external height, and the elements inside you will still be fixed. Of course it will be useless

Sorry, I misunderstood your request
According to your request, I can only use js Calculate the height of aaaa
aaaa
, and then calculate the height required for #bbb

Why do I feel like I don’t understand what you mean?

Your code looks like this.


It seems that the result is the same as what you want, no problem.

At the same time, I also tried it. You said setting the height of div=bbb to 70px has the same effect. There is no difference.

You don’t want the scroll bars to be displayed when the page is initialized? Even if you set the height to 70px, after adding your aaaa
, add a few more, bbb will still go down. Since it needs to be adaptive, what is the problem with the current effect?

Or maybe, I don’t understand what effect you want to achieve.

Chrome is good.

The screenshot you took is set to 70px. I tried it myself

The effect you want is impossible to achieve when the height of the parent element is certain

Try adding a few more aaaa
Even if it is 70px, the horizontal scroll bar will not be displayed.

If you insist on such an effect, then use the fixed positioning of the DIV to simulate it, and then use JS to control the simulated scroll bar.

But the complexity will be very high.

It seems that the height can only be hard-coded and cannot be achieved through a certain attribute. The picture you captured is set to 70px. I tried it myself

You can’t even write it to death

What you said aaaa
there is an indefinite number, you can add a few more, or use 70px to see the effect, it is still the same as you now The desired effect is different.

This is not a question of writing it to death or not.
