jQuery ui selectmenu vertical position offset (relatively to buttons in this line)

阅读更多关于 jQuery ui selectmenu vertical position offset (relatively to buttons in this line)

问题 In my form I place control elements in a line: button, select box, checkbox. It looks logically right. But since I've started using jQuery UI I see strange vertical of select box. Here's the example from jquery-ui site, a little bit shortened: https://jsfiddle.net/Tertium/z829pay7 $(function() { $( "#speed" ).selectmenu( { width: 200}); $( "#files" ).selectmenu({ width: 200}); $( "#but1" ).button(); $( "#but2" ).button(); }); Tested on jquery 1.11.2 and 1.10.2, jquery-ui: 1.11.3, all settings

Weird z-index issue, floating list items not showing above heading

阅读更多关于 Weird z-index issue, floating list items not showing above heading

问题 This is quite an interesting issue I'm having with z-indexes that I've never encountered before. Let me go ahead and answer one of your first thoughts you might be having: I've already set the positioning I need for each element I have a z-index on, it's not that. I've tried reordering things as much as possible, but basically what I have is two fixed elements, one is the website's heading text, the next is a div containing an unordered list of navigation items (each floated left and given a

How to fix an image position relative to another image with different screen sizes

阅读更多关于 How to fix an image position relative to another image with different screen sizes

问题 I'm writing a website/iPad app (using PhoneGap), where I have 1024x768 images on a slide show. I'd like to position another image, e.g. the home icon, on top of the 1024x768 images, at exactly the same position, no matter the screen size (e.g. high/low resolution PC screen, or 1024x768 tablet display). I tried absolute, but the position changes in different displays, and it's not the same position as I originally set up in CS 5. 回答1: Similar to the other answers, but if you prefer not to

Zooming on Chrome causes CSS positioning issues

阅读更多关于 Zooming on Chrome causes CSS positioning issues

问题 When I zoom in and out on my webpage in Google Chrome, items that are precisely positioned in relation to one another will change position. This causes many problems: For example, at specific zoom levels a div will overlap its containing div just enough to hide a border. Similarly, sometimes a 100% marker will not precisely line up with the 100% point. Is there any way I can ensure that the positioning of the items in relation to each other will not change when the page is zoomed in or out?

3 columns, middle one with flexible width

阅读更多关于 3 columns, middle one with flexible width

问题 I'd like to have a layout that consist of three adjacent divs. Side divs have static width (it may change via javascript) and center div fills a remaining area. When the first div's size changes it affect only the center one. It is similar to table (with dynamic rendering) that consist of three columns. Ok, but where is the problem. The problem is that if I put floating-left div into the first column, and block div in the second and third one, block divs behave in a strange way. They are

How to display a side panel on the left and Google maps api canvas on the right, filling remainder of page?

阅读更多关于 How to display a side panel on the left and Google maps api canvas on the right, filling remainder of page?

问题 I need to be able to have a side panel that fills the height of the page on the left and a map filling the rest of the page on the right. I would like the side panel to have a width of 300px, regardless of the size of the browser with the map to the right of it. Also, I am not able to move any of the divs within #panel, they are all just aligned one after the other. Here's my css: body {margin:0;} #panel {height:100%; width:300px; position:absolute; padding:0;background-color:#8C95A0;} #div1
