I've got a page which I need to serve via an iframe, but I need to only display part of the page, not the whole thing. My current code is: <div style="display:block;overflow:hidden;width:500px;height:350px;"> <iframe height="350px" scrolling="no" src="http://my/page/i/want/to/show/part/of/here/" width="500px"></iframe></div> I thought that the best option would be to serve the iframe within a containing div that has "overflow:hidden" so that it acts like a picture frame.

Absolute positioning with percentages giving unexpected results

阅读更多关于 Absolute positioning with percentages giving unexpected results

问题 Please consider this jsfiddle, containing this html code: <div id="container"> <div id="item">TEST</div> </div> And some CSS: #container { border: 1px solid red; height: 100px; width: 100px; } #item { border: 1px dashed purple; position: absolute; left: 50%; } The results surprise me. Looking at the W3 positioning props I'd expect the #item to have its left value at 50% of the "containing block": the #container . However, it seems to be at 50% of the entire page, not just the containing block
