CSS - why is - what happens?

My navigation bar is perfect. Centered on the page just like I want. I also want my header and footer centered on the page, like the navigation bar, content main.

Why my navigation bar for the mechanical and the header is not? I'm trying to understand the things I want.

margin: top | good | bottom | left

margin: 0 auto;  CSS stands for

margin-top: 0;

margin-right: auto;

margin-bottom: 0;

margin-left: auto;

To Center a page you need 3 things:

(1) a document valid type,

(2) with a width of container in pixels, ems or percentages.

(3) margin-left and margin-right to auto (default value of the browser).

  • Why is - what happens to my CF8 installation?

    Hello

    I recently bought a server with Windows 2008 Standard Edition and I bought a copy of CF8 standard.  CF8 installed on the server and everything went well.  Added a site to the server through IIS and the site if poster and all, EXCEPT for the contact page, on which I have a textarea with richtext.  On my dev machine it fine appeared and worked well, on the server it doesn't? MORE things like making text required with messages boxes do not work (it will make the CFML, but does not display the richtext box or the js alert when a required field is missing), but on my dev machine (which is my MacBook with CF8 installed), it worked fine.

    So I think for me, what is causing this and decide to uninstall CF8 and reinstalling CF8 (maybe watered installation) GUESS WHAT, now all CF code runs on the server as well now.  So now I'm happy and go to build another site on the server.  GUESS WHAT, same thing.  The original site now works fine, but the new site is not made the richtext boxes and alerts of required fields do not work.

    What causes this.  Is this something im doing? What is Windows 2008?

    Please advise, because I about to pull out my hair.  I can't keep uninstalling and reinstalling CF8 to make my sites to work 100% with CF8

    Thank you
    Cedric

    There are a ton of them.  While not all the specific IIS7, the main steps are the same. Just google IIS virtual directory.

  • Why this is happening and how to fix it.

    8B1A6108.JPGWhy is - what happens to my images in lightroom and when exporting? Help please.

    There is a hardware malfunction that causes your corrupt photo files.

    If the photos look good in Lightroom, but look like this when you export, you most likely have a hard drive malfunction (or possibly the computer's memory).

    If the photos seem corrupt before exporting, then you try to import photos using different materials (different card reader or other cable/USB USB port), run diagnostic tests; hard disk and the memory of the computer and if possible try to import photos to a different computer.

    Hello

    Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

    Note: You can print these steps or consult them in another browser.

    1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
    2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
    3. Remove the Firefox installation folder, which is located in one of these locations, by default:
      • Windows:

        • C:\Program Files\Mozilla Firefox
        • C:\Program Files (x 86) \Mozilla Firefox
      • Mac: Delete Firefox in the Applications folder.
      • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
    4. Now, go ahead and reinstall Firefox:
      1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
      2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

    Please report back to see if this helped you!

    Thank you.

  • What is the problem with the graphics on the upper right of the browser. Why is this happening?

    It gets a lot worse that what can be seen in the image on screen shot (below). This does not happen with other browsers (Safari, for example). This also occurs on the right side of my toolbar.

    The above mentioned page doesn't have to download, so here is a description of what happens:

    Flashing of the grey squares on the side right of the browser (the scroll bar and the parts of the web page) and on the right end of the toolbar.

    You can try to disable hardware acceleration in Firefox.

    • Firefox > Preferences > advanced > General > Browsing: "use hardware acceleration when available.

    You will need to close and restart Firefox after enabling/disabling this setting.

    You can check if there is an update for your display driver graphic card and search for hardware acceleration of related issues.

  • CS6 InD, what happened to the margin-top in EPUB CSS property?

    I've been playing with EPUB export in InDesign CS6. What struck me most surprised are the missing CSS property. What is the reason for which leave margin-top property paragraph styles? This is a characteristic, a bug or I'm just something wrong? Others noticed this too?

    Another thing that surprised me is the device that they use in the margins. Earlier we got em, but now it has pixel. No way to change this?

    A couple told us in the engineer that the programs for CS6 to PEPCON EPUB. He said, that it was intended as a feature, but after hearing this reaction, they consider it a bug and not expect to be fixed, perhaps in the first CS6 bug fix.

I'm on page that I bookmarked. So now, no? and what happened to the "mark this page" option initially drop down list? It's so easy. I have to develop records, files, plugins, etc...

    Add code to the file userChrome.css below default @namespace.

    @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */
    
    /* move "Show All Bookmarks" to the top of the Bookmarks drop-down list */
    #BMB_bookmarksPopup #BMB_bookmarksShowAll {-moz-box-ordinal-group:0}
    
    /* move "Show All History" to the top of the History drop-down list */
    #PanelUI-history > * {-moz-box-ordinal-group:3!important}
    #PanelUI-history > label.panel-subview-header {-moz-box-ordinal-group:1!important}
    #PanelUI-history > #PanelUI-historyMore {-moz-box-ordinal-group:2!important}
    

    The file userChrome.css (UI) customization and userContent.css (Web sites) are located in the folder of chrome in the Firefox profile folder.

    • Create the folder chrome (lowercase) in the .default < xxxxxxxx > profile folder if the folder does not exist
    • Use a text editor such as Notepad to create a userChrome.css (new) file in this folder (the names are case-sensitive)
    • Paste the code in the userChrome.css file in the Editor window and make sure that the userChrome.css file starts with the default @namespace line
    • Make sure that you select "All files" and not "text files" when you save the file via "save file as" in the text editor as userChrome.css. Otherwise, Windows can add a hidden .txt file extension and you end up with one does not not userChrome.css.txt file
