问题 I have read a lot of different articles about available methods for vertical centering using CSS. I understand how everything works, but I have found a lot of phrases like layout using tables is considered bad practice ? I found that using display : table is supported by most of the old browsers, even mobile browsers like Opera Mini for antique phones. Please explain why is it considered bad practice to use divs with display : table and what is the most well-supported way to align vertically

问题 I am having a problem trying to change the css of a button in JQuery Mobile.

问题 I'm trying to create a day calendar for a workout log (similar to that of myfitnesspal) and I'm having some difficulty creating a swiping day calendar to track my logs.

问题 I started by using the method described here in order to create a Mobile redirect, and it works perfectly. What I need to do next, however, is prevent it from happening on any page other than the homepage.

I'd love any advice the community might be able to provide as to how to accomplish this effectively. 回答1:

问题 I'm trying to pop up a very simple "are you sure?" popup in jQuery Mobile. But if I use the data-rel="popup" on the button, nothing happens. If I remove the data-rel it opens - but as a full window. The logic works well, but still, I'd like to see a popup.

The 2 elements to look at are the button "clearHistory" and the popup itself "history": <

问题 I would like to use the JQuery slider for my mobile application http://docs.jquery.com/UI/Slider However, using the Slider plugin, requires me to use the entire JQuery core (29kb) + Slider plugin (6kb). Typically, that's okay but for a mobile application - that's a lot of data. Question : Anyway I can use the JQuery Slider and eliminate any bloat that might exist in the core? I would really like to reduce this 29kb core down to something much smaller. (e.g. just using Sizzle + plugin or
