Permanent Lightbox that can't close

Hi!

For my pretty big webshop we are planning a two month summer break to do some work and redesigning on the website. Now i was thinking how can i prevent people from being on the website and ordering things in the meanwhile. I want to show them a message we are on a break and that further they can’t do or look anywhere.

Now the only thing i could think of was making a lightbox that will pop up right away (so also when they find my site through a google link) that they can’t click away or close down… but that seems impossible, because with just simply clicking anywhere or hitting the escape button the lightbox goes away…

Anyone that can help or has a better idea how to do this?

Thanks in advanced.

Es ist klar welches deine Muttersprache ist.

But instead of opening a lightbox, why not just creating a page and link to it?
So whenever the user tries to open a certain page, he/she will be navigated to the → BREAK-PAGE. So all you would have to do is to change the links to the BREAK-PAGE.

User clicks a button to enter a page, and normaly he assumes to be navigate to the right page, but instead will be navigated to the BREA-PAGE, with the SORRY-MESSAGE.

Of course there also would be a way, by using the LIGHTBOX.
For example one idea which comes into my mind, would be to use …

—> onVieportEnter on your ‘#page1’ element.

Everytime when you enter the viewport of the page, an event triggers and opens again the lightbox. That means → you click the lightbox away (closing) → entering the viewport of the page, it triggers an event → opening the LIGHTBOX again.

If this does not work…
Generating a code, which checks every SECOND, if the LIGHBOX is openend or not (when clicking onto the ENTER-BUTTON) —> setIntervall();

This are just some first ideas which comes into my mind when regarding your issue.
Surely there are even more possibilities.

Thank you so much for th advice!

I think the first option to link to a break page is a good one.

The thing with the lightning box was that i tought it was the easiest way for me to work on the new design of website while it is “offline”. So i can do all the work but no one would be able to see it yet. And when i finished the redesignig i would just remove the lightnighbox…
