css3

问题 I have the following HTML and CSS here http://jsfiddle.net/XQ5c9/. I am trying to center all of my content on any screen size/browser.

Here is my CSS (both HTML and CSS are in the jsfiddle link): @import url(http://fonts.googleapis.com/css?family=Roboto+Condensed); html{ /* font-family: 'Roboto Condensed', sans-serif;*/ font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue",

问题 I am building a portfolio website that uses only CSS3 to display a grid and filter out thumbnail images. You can see what I've done here. I got the filter functionality to work by using this tutorial and using the :checked pseudo class. The grid is made using css3 columns to create a seamless responsive photo grid. I used Chris Coyier's example. Everything works in most modern browsers, but it breaks in mobile safari for the iPhone. Upon further testing, it seems to also break in the Sleipnir

问题 I'm trying to implement and new layout for my site. I am capable of implementing this using JS but I'm trying to use pure CSS.

问题 I want my Header text (Events, Blog, About) to LAY ON TOP OF the "Images/Damask.png" image. Instead the image is displayed at the very top of the header with the text BELOW the image. <header> <header> <img src="Images/Damask.png" width="100%" border="0" height="200" class="header"> <a href="index.html" id= "logo">![enter image description here][1] <h1>J Barnes Events</h1> <h2>Indianapolis's Finest<h2> </a> <nav> <ul> <li><a href="index.html" class="selected">Events</a></li> <li><a href=

问题 Is there a way in CSS to modify the parent element, given the first child? In my case, this would be to format a table cell differently if the first child is a link. <td>Hello</td> <td><a href="go.html">Go here!</a></td> <style> td { padding: 5px; } /* Normal cell */ ?? { padding: 0px; } /* Cell with link as first child */ </style> 回答1: No, but you can think of a different approach and do something like: td { padding: 5px; } /* Normal cell */ td a { margin: -5px; } /* Cell with link as first

问题 I have designed a template and I wanted it to be responsive, so I included some media query files to achieve it. However the max-width: 500px file is not detecting properly. I really don't know how to solve it. The website works fine in all the other desktop screen resolutions. I don't know why it does not work in screen resolutions below 500px. All I did in that css file (medium-tab) was to turn the display to none for the menu-container and to activate the mobile container by writing

But there are a couple of problems: The max-height must have

问题 Another question(s) from design class 101. I am using the Marquee tag for scrolling text for prototyping purposes. A: How can I get the text to pre-load on the page and then start moving. (Versus coming in at the sides of the screen to begin) B: What is the best alternative (and the purest replacement) to move away from Marquee that will accomplish A? a simple example would be beyond cool.
