Horizontally center an element

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.

I need to put the main product image in the middle of the page. Make sure it stays centered on mobile too, so it looks good on any device.

Before I hand this off to the content team, center the main product image. Make sure it's not just technically centered but actually feels balanced on the page, and doesn't shift around when the window resizes.

The client just complained the hero image on the new landing page looks off-center on their tablet.
The client just complained the hero image on the new landing page looks off-center on their tablet, even though I used the standard centering method. I'm afraid if I just tweak the CSS, it'll break on other screen sizes. Is there a more robust way to ensure it's truly centered across all devices without introducing new issues?

I spend too much time fighting with horizontal centering across different browsers and devices.
I'm constantly losing time trying to perfectly horizontally center elements, especially images and custom components, across all the different browsers and screen sizes. What habit should I change in how I approach this common task to stop the endless tweaking and get it right the first time?

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.
