How to move fluid divs the correct distance on/off screen using CSS3 transforms?

阅读更多关于 How to move fluid divs the correct distance on/off screen using CSS3 transforms?

问题 I have a fluid container which contains a number of absolutely positioned fluid divs. I want to use CSS3 transforms to move these on and off the page. The problem i am having is that when using transforms you either use exact pixel amounts or percentages of the element itself. So you can see an example of the sort of thing i'm referring to (this is just a test example) at http://jsfiddle.net/K3uPY/ This is using a transform of 1000% to move them offscreen which is obviously not a good thing

Absolutely positioned images in Chrome/Safari

问题 My client's websit has a navigation bar in the form of a wide image banner. I'm using the HTML <area> tag and JavaScript to overlay navigation buttons (which are themselves images) whenever the user mouses over certain regions of the banner. The buttons are absolutely positioned over their respective <area> 's, and are hidden/shown based on the mouse position. While I have it working on Chrome, I've noticed that the buttons are appearing in the wrong place on Safari. I've struggled to figure

Is MPL pos an undocumented metafunction?

阅读更多关于 Is MPL pos an undocumented metafunction?

问题 There is the following example code in the BOOST MPL documentation of the find algorithm: typedef vector<char,int,unsigned,long,unsigned long> types; typedef find<types,unsigned>::type iter; ... BOOST_MPL_ASSERT_RELATION( iter::pos::value, ==, 2 ); However, I cannot find the documentation for the iterator's pos metafunction. Can I use it reliably? I'd like to use it somehow as: typedef vector<type1, type2, type3> types; template <typename T> void File::write(T value) { BOOST_MPL_ASSERT(

阅读更多关于 I'm trying to assign random integers to struct members, but it doesn't work properly

问题 I'm doing an assignment where I have to randomly place players on a field with random coordinates, but those coordinates must be unique or else they must be regenerated. I'm trying to randomize integers and assign them to struct members. However, what I'm doing right now doesn't seem to work properly according to my professor. This is the struct: struct player { int x; int y; int direction; int id; int presence; }; Those are my two arrays, one for the field and one for the size of the team on

Keep transition effect on 1 div from moving the div that follows?

阅读更多关于 Keep transition effect on 1 div from moving the div that follows?

问题 1. I have a 4 column row of divs that move a little when hovered (with margin and padding). How can I keep this movement from moving the content that is below it without adding a fixed height . It is in a fluid layout so with a fixed height that allows enough room for the movement, the content below starts to get too far away as the window width is reduced and the images scale down. 2. For the bounty you need to make the jsFiddle work. It seems that even though I have transition: all , all of
