Make a div fill the height of remaining screen space

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

Make the 'main-content' div fill the remaining height of the screen below the header and above the footer. I need to push this live by end of day.

Before I pass this to the client, ensure the 'main-content' area always expands to fill all available space between the header and footer. It should adapt gracefully, even if the user has a huge monitor or a tiny laptop, so there are no awkward gaps.

The main content area isn't filling the screen, leaving a blank space above the footer.
The new dashboard page has a fixed header and footer, but the 'main-content' div in the middle isn't expanding to fill the entire vertical space on larger monitors, leaving an ugly gap before the footer. The project manager just saw it and is concerned it looks unfinished. I'm afraid of using absolute positioning and breaking responsiveness. What's the best way to make that middle section dynamically fill the remaining screen height without messing up other elements?

I frequently struggle with making content areas dynamically fill remaining screen height.
I constantly waste time trying to make a central content div dynamically fill the remaining screen height, especially when there's a header and footer. It often leads to scroll issues or content overflow. What habit should I change to consistently and reliably implement 'fill remaining height' layouts across different screen sizes?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from HTML's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
