about:blank
what actually happens when you type about:blank in the bar.
you have probably typed something stupid in the url bar at 1am. i typed about:blank. the page that came back was just nothing.
not loading. not an error. no "you are offline" dinosaur. dark mode is black, light mode is white, and that is the entire page.
i sat there for a second thinking wait, is this a website. who hosts it. can i inspect it. why does a blank tab even have a url.
so i looked it up. the answer is simpler than it looks, and kind of nicer.
wait, what even is this
about:blank is not a website.
there is no server. no domain. nobody bought this on godaddy. your browser just invents it.
the about: part is a url scheme, same family as https: or file:, except this one never leaves your laptop. the browser is talking to itself. chrome has a whole pile of chrome:// pages. firefox has about:config. about:blank is the quiet one. empty on purpose.
so when you "visit" it, the browser cooks an empty html document in memory and shows it to you. no dns. no request. no connecting. you were never going anywhere.
open inspect. you get basically an empty <html>. that is not a bug. that is the whole thing.
is it fake
not fake. just internal.
browsers need a page when you have not picked one yet. a new tab with no homepage. an iframe with no src. window.open() with no url. a popup that is about to load something. you cannot have a tab that is literally null. the window has to exist. so they made a page that is allowed to be empty.
it is the default for "i don't know yet". a legal blank. the url for nowhere.
that is the part that stuck with me. the rest of the internet is "go here". this one is "you are not going anywhere, and that is fine".
what it actually means
technically: an empty document. a blank html page that never hit a network. it is in the spec. browsers have needed this for decades. not a meme.
the nicer meaning is dumber.
it is the only tab that is not trying to sell you something, ping you, autoplay, or make you feel behind. no feed. no cookie banner. it does not even want a favicon. it is just "i have not decided yet", and then it stays there.
people will turn that into a metaphor. empty canvas. new beginnings. reset your life. i don't buy that. it is just the browser being honest. you did not go anywhere, so there is nothing to show.
i keep too many tabs open. one for college. one for github. one for some random thing from 1am. all of them want something. this one does not even know what wanting is.
go look at it
type about:blank in the bar. that is the whole site. no landing page. no subscribe. nothing to ship.
the blank tab will not start dsa for you. i still have to do that.
that's it.
