问题 I want to create a header with two columns, one for the "brand name" and one for buttons, such as login, sign up etc. However I can't wrap my head around how to vertical center them inside the header, because the buttons are much taller than the brand name. I also already stumbled across this question, however the solution suggested there did not resolve my issue. What I have got so far: header { border: 1px dotted magenta; } header:after { content: ""; display: table; clear: both; } #left {

问题 I am basically styling a long essay with various images scattered throughout. I would like the first image to "float: left" and the second one to "float: right". I know that I can style the images like this: img { float: left; } This makes each image have the same style. How do I style each image differently? I tried to put each image in a different div class, so that I could style them differently, but it didn't work. I also understand, that I could style each image in the html tag, like

问题 so I'm having a hard time understanding the circumstances under which a float can have margins collapse through it and how that affects the position of the float. I've included a page that seems to show two different behaviors in the same page. The red float seems to be positioned before the margins that collapsed through it, whereas the blue ones down below seem to have the margins collapse through them and then be positioned after those margins have collapsed. Any help would be much

问题 Why do we say that the display property of floated elements may change to block level, instead of saying inline-block , because it starts taking the space according to the content it wraps? 回答1: inline-block means inline level, block container. inline-level elements participate in the layout of a line (or multiple lines). This affects line spacing and the vertical alignment of other elements in the same line. Floated elements do none of that. The participate in block formatting contexts, not

问题 I'm having a problem with floating a container to the right in IE7. Everything looks fine in IE8+, Firefox, Chrome, and Safari but the elements within the container wrap for some reason in IE7. I've set up a fiddle at http://jsfiddle.net/aagC9/. The problem I'm seeing is visible in the IE7 Browser Mode/Document Mode found in IE9 (it's also in IE7 on XP but I figured this would be easier for people to check out). While it seems like many people have run into similar problems, their solutions
