That makes sense because if you set the x-axis to 100% its aligned right, 0% and its aligned left, 50% and its aligned centre. If the percentage width of the element related to the zero point of the background image then 100% would place it wholly to the right of the element. At 50% the image's left side would start at midway in the element but then the percentage would be meaningless in terms of the element itself. It would be of little practical use. This never occurred to me before you mentioned it. -- Kind Regards Chris Price [EMAIL PROTECTED] www.choctaw.co.uk Tel. 01524 825 245 Mob. 0777 451 4488 Beauty is in the Eye of the Beholder while Excellence is in the Hand of the Professional ~~ >> Sent on behalf of Choctaw Media Ltd << ~~ Choctaw Media Limited is a company registered in England and Wales with company number 04627649 Registered Office: Lonsdale Partners, Priory Close, St Mary's Gate, Lancaster LA1 1XB • United Kingdom ***List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfmUnsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfmHelp: [EMAIL PROTECTED]***
Re: [WSG] Background-position in percentage
This is because x and y axis are not used in HTML only in JavaScript as far as I am aware.

> Does anyone know why [bg image positioning] was created that way, and/or can you tell me if there's some very useful thing this rule allows you to do? As Alex pointed out this is the way to use if you want to right-align or bottom-align a bg image. Also for horizontal/vertical centering this is an easy way to go. I agree with you that the way it works might seem strange at first but if it wasn't it wouldn't work as outlined above.

[WSG] Background-position in percentage
I've just spent a bit of time looking at how background-position works when expressed as a percentage: background-position: 90%; and I'm wondering why it works the way it does. Here's the best way I can describe the effect of (90%, x-axis) positioning with percentages: "to position the image such that the point 90% across the image is aligned with the point 90% across the element". There's something rather counter-intuitive about that (it's even hard to describe!), and I've tried to explain it in teaching people about CSS and found that people are rather baffled by it. Does anyone know why it was created that way, and/or can you tell me if there's some very useful thing this rule allows you to do? That is, as opposed to a simpler rule like "image is offset that amount to the left" which is what I assumed when I first came across it. Please consider the environment before printing this e-mail.
