问题 I'm trying to use a :first-letter pseudo element on a navigation menu.

I can see it working for the first element on the <ul> tag if I adjust it to this: nav ul:first-letter {font-size: 150%;} but still can't get exactly what I need; <li> 's inline whose

Animating css's after and before selectors in jQuery

由 落爺英雄遲暮 提交于 2019-12-13 16:07:38
问题 Is it possible to animate CSS's selectors :before and :after in jQuery's .animate() function? If not, what is the best alternative to doing that? 回答1: In short no - jQuery does not support pseudo element animations or even selectors I believe. You can however animate pseudo elements using css3 transitions but it is to note that only Firefox 4.0+ supports it currently, so your playing field is very limited. If it's that important, just create new child elements in the element you want to

问题 I am trying to toggle the display of an :after pseudo-element (ie.to show/hide it) using jQuery. I successfully toggled the display of a div, but want to do this now with :after .

I'm trying to accomplish this by using content:counter(paragraph) in CSS so that every paragraph block I create generates a number to the left of it. .pass { counter-reset:paragraph; } .pass p:before { content:counter(paragraph); position:absolute; font-size:0.6em; color:#999; margin-left:-3em; counter-increment: paragraph; } It works fine, but the problem is I can't figure out how to align the numbers so that they

Using before and after pseudo-elements on background image

由 ε祈祈猫儿з 提交于 2019-12-12 12:25:30
问题 I am wanting to construct navigation items from three (background) images, with the first and last a fixed width, and the central a variable width, depending on the width of the text in the nav item. I have been led to believe that using the pseudo elements before and after would be the best method. When I try this though, the main (central) background image for the nav item is overlapping with the before and after background images. You can see what I mean on this page. Here is the CSS: .box
