position

问题 I have a element inside a block. The block height is 500px and the width is 100% of the screen. In this configuration, i'm aware i can see 500px of the original height (because of the overflow:hidden property i set in my css file).

This is a image to help you to understand : I need to know if there is a way to

问题 On a webpage I have a container div and inside it two divs next to each other. In the first inner div I am trying to set up a CSS table that has 4 columns that evenly fill the div. The problem I am having is that the cells seem to get their width relative to the page's width, not the table/it's parent div. If I decrease the width from 25% to something lower, it will fit, but if I scale the page, they will still wrap, as the div on the right hits the rightmost table cell. How should I setup

With this code, I was able to nicely overwrap big picture on the left, but text and small picture still doing what it wants. I need to avoid flexbox, since I need to support also IE8, or atleast IE9.

These floated divs should expand the width of the absolute parent. <div id="parent"> <div id="stretchable-div"> <div class="child">text</div> <div class="child">another text</div> <div class="child">more text</div> </div> </div> Problem being, this does not work when the original

问题 For school i'm making a website for a mobile. There are multiple columns, 1 for menu for example, 1 for the context of the book and the one next to that will hold footnotes and image information.

问题 I have a button that resizes a div from 200px - 290px In this div elements exist that are positioned using calc(50% - 25px); 25px = half width of child - so they are positioned centrally. I'm using jQuery's ui.swappable to swap elements, but the issue you is they seem to take on their calculated value permanently once swapped pre-swap left:calc(50% - 25px); post-swap left:74px Is there a way to swapping the calc(50% - 25px); instead of the value post calc? $(this).position() 回答1: Solved this.
