Right now I'm using a full page layout and p:layoutUnits and page composition in my webapp. I have a fixed header with a menubar, and a content layoutunit, and that's all. It was easy to set up, but in IE (7) when I navigate to a new page the whole page reloads (visibly), the header is cleared then loaded, and - even more annoyingly - the menubar is displayed for a second with all the menuitems visible.
In other browsers this effect is not really visible, sadly, IE 7 is my target.
Now I'm thinking about saying goodbye to p:layoutUnits and implementing the layout with simple css magic and fixed div for the header - would it improve display in IE? Is there anything else I can do to make it faster and smoother? I'd like it to look like the header is not changing at all, only the content.
How about using iframe? Would it allow bookmarkable URLs?
I see this is an old question, but I'll throw in a new answer anyway...
PrimeFaces 3.0 <p:dataTable> supports in-table scrolling. You set a fixed height and width for the data table on your page and within that box the data table is rendered with a scrollbar. The column headers and footers stay put and you just scroll the rows. They just cleaned up some format bugs in their nightly snapshot builds that make the <p:dataTable> look great in IE 7. Might be worth a second look at PrimeFaces for those who (like me) have to support older IE browsers.

I've finally decided to say goodbye to p:layout. I have a long table that's two or three times the size of the screen. If I put it in a scrollable layoutUnit then the scrolling is so slow that it is really annoying (tested in IE, Firefox and Chrome - equally slow). Perhaps this widget was not intended for this kind of use (displaying scrollable, long content), but now it is clear that I'll have to do a proper CSS design and stay with raw DIVs.
Nevertheless it was great for quickly putting together an application GUI that can be shown to customers.
For those struggling with layouts, follow BalusC and use simple divs/css and JSF 2.0 Templating. I started with PrimeFaces layouts and could never get it to work with complicated designs.

So I learned about CSS grids today, and I had a question that I could not find an answer for. In my site I am creating, I used HTML tables as I did not yet know about css grids. Now that I have learned about them, I can see that grids are more useful and flexible in layout and style.
With the HTML tables, I can make it look perfect in a browser such as Google Chrome, but then I test it in FireFox and it slightly moves the divs around that I made.
If I used a grid system for a layout, and put all the content into that instead of using HTML tables, and then use the fr in css, would it keep the layout the same across web browsers? It would seem that way to me, since no matter what size of browser window or type of browser you are using, the fr keeps the grid to using 100% of the page size.
I apologize if what I am asking doesn't make too much sense. I tried to word it as best I could.
Yes. It will look the same if the browser supports grid layout.

I have a responsive Drupal Zen subtheme that I hacked together about a year & a half ago from some CSS & HTML that a non-Drupal designer handed off to me for my website. I've known that in certain layouts, it is buggy, and needs to be fixed, but I just haven't gotten around to it. After repeatedly reaching out to a local Drupal developer (and offering to pay him), I've gotten tired of waiting, and just need to fix this thing.
My bounce rate for folks on mobile devices is awful.
The URL is http://developcents.com. The homepage looks decent on any device. Internal pages need a lot of help, though, when viewed in certain screen sizes (including mobile devices). Let's use http://developcents.com/blog as an example.
In the below scenario, my question is not how to find the CSS files themselves. Rather, my question is, how can I find the necessary CSS settings using Firebug Lite, so that I can debug the CSS through my browser, instead of having to manually update each CSS file every time I want to test a change?
I can't find the actual CSS-styled divs, blocks, etc... causing the layout to break under certain dimensions. I know how to find, and edit, the CSS within the CSS panel, but I can't track down the specific CSS in this instance.
Additionally, as a secondary question, if you want to provide pointers on what I actually need to change, then please be my guest! But if you point me in the right direction on how I can go figure it out myself, that's fine too. :)
Let's get on to the scenario (which you can easily see by testing it yourself):
When I resize my browser window down to a certain size, the links & tweets section in the left sidebar move over to the right, so that the left side of the navbar aligns with the right side of the header area, while the content spans the full width of the page, except for the left margin, which stays in place but gets wider. Basically everything below the header gets screwed up, and it's easier to see the problems than explain them (so go test it).
Using Firebug Lite in Chrome, I can't seem to find the left margin for the "main" content area (see this screenshot clearly indicating the yellow margin), nor can I find the CSS for the navbar / tweets block (which I presume is some sort of float).
To modify the CSS within Firebug or Firebug Lite just select an element inside the HTML panel or inspect it via its inspector. Inside the Style side panel you'll see all CSS rules applying to the element.
Clicking the name or the value of a CSS property opens an inline editor to allow editing it.
On the right side of each rule you'll see the name of the style sheet, which contains the rule. Hovering it displays you the full URL and clicking it allows you to inspect it within the CSS panel.
You can also edit the styles directly within the CSS panel, which lists all style sheets available on the page.
Note: The changes you do there are not permament, i.e. on the next page reload they are gone! To make permanent changes you need to edit the files on the server.
Also note that I'm referring to the panels within Firebug. The panels within Firebug Lite basically work the same, though may look and work a little bit different. Furthermore Firebug Lite is not maintained anymore, so there's no guarantee that everything is working as expected.
I'm trying to make a sample web page to get acquainted with HTML5, and I'd like to try replicating Facebook's page layout; that is, the header that spans the entire width of the screen, a small footer at the bottom, and a three-column main body, consisting of a list of links on the left, the main content in the middle, and an optional section on the right (for ads, frames, etc.). It's neat and displays well in multiple window sizes.
So far, I've tried to accomplish this with a <header>, <footer> and a <nav> and <section> block, respectively. There's a few anomalies with the page, however. The footer (which contains a simple text block with copyright info) appears at the top-right of the page below the header when the window is maximized. On the other hand, when there isn't enough space to display everything in the window, it places the main body text below the section. In other words, it keeps moving elements around to fit the window.
Could someone please tell me how I'd achieve the look I'm going for? I've tried playing around with a few CSS attributes I read about through Google, but I'm pretty sure I don't know what I'm doing, and could really use some guidance.
Thank you!
This isn't an HTML5 question as much as it is a basic understanding of HTML and CSS. If you're going to jump in to web dev you're going to need to understand basic CSS like floating etc. I would recommend some tutorials on YouTube or NetTuts. Just play around with a few divs, move them around the page, manipulate them with CSS and it will start to come together. Then making a three column layout with fixed header and footer will seem like a piece of cake.
Floating Divs w/ CSS
I find CSS to be super hard. It is quite difficult to make a page that looks good and works on lots of different platforms and browsers. You may find it easiest to use a css framework, such as Bootstrap.
Drop that into your website, and use it to make your layout. Use the dev tools for your browser (Firebug for firefox) to examine the styles that are being applied to the various elements. Modify the styles to suit your needs.
HTML5 doesn't really give you a page layout for free. The elements you mention (header, section,etc) are used to create semantic pages, rather than to specify how they should be displayed.
Can't help much without your code. But I am sure it is because of float issue. add this CSS property to your footer clear: both
Hope it might help.
I'm not sure if you're trying to make yourself a little hack, or if you're looking for a complete library that will do all this for you, but if you're looking for the latter, I recommend Twitter Bootstrap, which is a cross-platform solution for implementing many HTML5 features, and even resorts to fallbacks for non-modern browsers. The only drawback is the requirement of jQuery in order to initialize the components that are responsive*. However, this is optional if you are not looking to implement these features. The responsive design, amazingly, does not require javascript since it is pure CSS. Hope this helps!
*Edit: meant "interactive" there, not "responsive."
I know there's several questions on this already, but I cannot find a solution anywhere.
Basically, I have CSS styling the body to fullscreen with no scrolling. Within this are 2 divs, for sidebar (left) and content (will be a map control if I can get past this problem).
Within the left sidebar I have 2 divs (at the moment), one has a simple entry form for an address to search for (which can be set to a static height, 9ems or 100px), the second is intended to hold the results in a vertically scrolling list in the remaining space
I almost got there - IE 8, Firefox, Chrome, Safari, and Opera appeared all to be working fine - then, as our Corporate web team insist on IE6 compatibility (or at least the page should be usable), I tested it in IE6 - no scrollbars, and the list is extending beyond its parent div. Playing about a bit more with CSS, I get the scrollbar, but the div seems to be inheriting 100% height from the document.
So far I've been struggling for about 4 days with this, so any help or insight is appreciated.
Thank you
For situations where I absolutely really HAVE to support IE6, I use conditional comments to add extra HTML and CSS, and possibly hide other stuff. Making layouts for IE6, IMO, basically comes down to "whatever it takes" - ditch proper document structures, endulge in table-based layout, use spacer images, etc. etc. Especially sizes expressed as percentages are horribly broken in IE6 - whoever implemented them apparently didn't have the faintest idea what they were supposed to mean.
I'm doing the first bit of web-page development I've done in years, in VS2008, using VB.net. I have a fairly simple layout, which is using several nested tables. IE6 displays the layout just fine, but Firefox for some reason shows the whole thing in a small panel at the top of the page, with a scrollbar. Can anyone suggest something basic I am likely missing?
There is a big difference in a way that IE6 renders HTML and especially tables. If you want to support it you should write explicitly all the position related styles like width, padding etc, just create a css file for table style.
The good news are that IE7 and 8 are mush closer to the standard.
