When it is not acceptable to omit the Alt tag on an image

I am writing just a page of image gallery using CSS3 and HTML5 that has the two tags for each photo img. All photos are of artifice, with nothing much to differentiate verbatim, I does not include the text with the image.

The CSS all withdrew with the auditor CS3 css, but for alt tags missing and the message says something like "looking for information on where it is possible to omit the alt tags" for each one missing, which is what I expected.

Anyone can indicate when it is permissible or acceptable missing alt tags, or is there a workaround that is satisactory?

Howard Walker

When an image has a purely aesthetic function, it is reasonable to omit or provide the alt attribute values vacuum (it is not a tag), because that's when the image does not contribute nothing to the meaning or the meaning of the page.

Think of it this way.  When someone views your page with images disabled, when you want them to see that a significant image is missing (and potentially get it)?  This is what the value of the ALT attribute.

    "Alt" tag is a part of the HTML languageand that of the written word to make sure that the site visitor will see or understand the content of the photos, even if it has a bad connection.
    as follows:

    Everything is fine with the width or height, but when it comes with the 'alt' it never appears.

    ALT is not for ToolTips, this is the bad behavior of Internet Explorer. To display a ToolTip, you must use the title attribute. Indeed, in order to create a real web standards compliant Web pages, you must specify both. ALT is shown if no image is available, the title is for the ToolTip.

    USE: alt="Google Chrome" width="33" height="32" title="my tooltip"
    
  • remote device does not accept connections is the error that I also get what is a proxy?

    There are some sites that I can't connect to Internet, I get remote device will not accept the connection and check the proxy. I don't know how to solve this problem, I don't know what is a remote device, and I don't know if I have a proxy. Please help, I work on surveys and freelancing and you need to get to my sites.

    This just sounds like your Internet is cut, not a Firefox problem.

    But I'd still Try Firefox Safe Mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • Password not accepted after locking the computer.

    Hello
    I know it is very old thread, but I have this problem on my computer and don't really know how to solve. @MrGlHayman solution did not help and I tried also the onscreen keyboard to enter a password but nothing seems to work.

    Thanks for any help

    Hi Natrezim,

    Welcome to the Microsoft community.

    According to the request, I understand that you are unable to connect to your computer, because the password is not accepted. I appreciate your efforts to solve this problem.

    To help solve your problem better, could you give us the following information?

    1. Do you receive an error message when you enter your password?
    2. What is the standard account or an administrator account?
    3. You have another user account on your computer?

    If so, then I suggest you log on to the other user account and change the password of the account that you are unable to connect to and see if the problem still persists.

    To change the password of the user account follow the steps below.

    1. Click on Control Panel
    2. In the Control Panel select user accounts
    3. Under user accounts , select account management
    4. Under accounts , select change password

  • When I'm not on my computer, the network disconnects, and I need to reboot Windows XP to run again.

    original title: it is a boot sector virus

    Please no one knows the answer?

    I use MSE on XP. Have all implemented the automatic updates firewall that all fixed at a fairly high level of security, and to update and scan with MSE usually twice a day. When I'm not using the computer I disconnect the network and reconnect when then necessary safety precaution.

    Sometimes, when I return to the computer is not found on the network, and the only way to restore the network connection is to re-boot. Then, I find it almost impossible to re-start as he died within 5 seconds after pressing the power button / stop. I tried holding the power button for a few seconds, but nothing helps I just keep on pushing sometimes for dozens of attempts and it stops automatically turn off the power. He intercepted not eventually if I keep on pressing him for dozens and dozens of attempts. It is?, is it a virus of a description, and if this is what and how is he riding in, on and why is MSE does not pick up.   I had similar situations where the IP address of my printer (Ricoh Aficio) has been changed, then turn off the printer and thrusting me on an audit of the laborious systems. ?.  Anyone has any ideas.

    Thank you very much

    Bob.

    PS Merry Christmas and a happy new year to all.

    Of course, it sounds as if you use the power button on the computer case.  Otherwise, good.

    Then, I find it almost impossible to re-start as he died within 5 seconds after pressing the power button / stop. I tried holding the power button for a few seconds, but nothing helps I just keep on pushing sometimes for dozens of attempts and it stops automatically turn off the power. He intercepted not eventually if I keep on pressing him for dozens and dozens of attempts.

    I guess that until you're away from the computer, disconnect from the network.  Even if you don't have the computer off, disconnect is still excessive.  However, if you do this, Windows should not bother you that you describe.

    During your absence, the computer go to sleep or Hibernate mode (if so, which) or have you configured it stays on indefinitely until you deliberately shut down?  If the computer is set to go into sleep or Hibernate mode after a certain period, you have the same problem reconnecting to the network if you return before the computer is spent in sleep mode or Hibernate mode?

    You have Service Pack 3 and the subsequent critical updates installed (for example, you use automatic updates)?

    The next time the problem occurs, open the event viewer (start > run > eventvwr > OK) and look in the Application logs and system errors or warnings.  By default, when you open the log event viewer must be sorted with the most recent events at the top.  If not, click the title once (or twice) of the column to sort.  He can't go very far back to find questions.  If there is an error or a warning, double-click it to display the property page.  Then click on the copy icon (right underneath the up/down arrows).  Then paste in your response here.

    You have your router configured to disable the SSID broadcast?  Even if it sometimes seems on Web sites for safety, it does not add to your safety really but creates network problems.  Do not disable the SSID broadcast, especially for Windows XP machines.  See http://blogs.technet.com/b/steriley/archive/2007/10/16/myth-vs-reality-wireless-ssids.aspx as this article points out, also not use MAC filtering in your router.

    Another thing that might cause problems of reconnection (especially if you have your router's SSID broadcast disabled) is a connection to a nearby unsecured wireless network.  You should look through the list of preferred networks tab in wireless network your wireless adapter properties dialog box, and 'Delete' you don't want to connect to all networks.  To get here, open network connections (start > run > ncpa.cpl > OK), right click on the wireless adapter and choose Properties.  Then go to the wireless networks tab.

    Even if you have properties of the adapter wireless open dialog box, select your network from the list of preferred networks and click Properties. Then click on the tab 'connection '.  What is the box checked for automatically "connect if this network is in range"?

    Finally, in regards to your printer, it is a recommended practice to configure devices like printers have a static IP address instead of the obtain an IP address from the DHCP server on the router.  As you have observed, in some circumstances (the printer is off for awhile), the router can assign a different IP address for the router than he had when you first set up the things.  Some wireless printer drivers (HP, for example) are smart enough to deal with this, but most is not.

    Read the manual of your Ricoh printer to determine how to assign a static IP address.  Pick one that is in the same subnet (i.e., the first 3 bytes of the IP address are the same as your other IP addresses), but out of the interval used by the DHCP server on your router.  You can find this information from the router configuration utility.

    For example, the DHCP server on my Linksys router is configured to assign not more 10 starting at 192.168.1.100 IP addresses.  Which means that the first computer to connect will get 192.168.1.100, the second 192.168.1.101 and so on.  So I configured my wireless printers to have a static IP address that is lower than, for example 192.168.1.50.

    After you set up the printer, click Start > printers and faxes.  Right-click on your printer, and then select Properties.  Click the Ports tab.  Already, the correct port must be selected.  Click on Configure Port.  OK your way out and enter IP address static, that you assigned to the printer.

    Recently, I downloaded all the files for CS2. There are 3 online for CS2 configuration files.  There was an another daughter for Extras and a zipped to go live.  I click on disc 1 and he started very well, put in my code, when he asked for it.  Then, he asked me to insert disk 2, I had them in the same folder and I thought he could see it. not having not other options, I went back in the folder and double clicked on disc 2, even if it started at the request of insert disc 2 remained, and the only application installed was Photoshop.  I even went so far as to burn all files on an individual disk and insert them when it ask you and still did not work?

    then 2nd disk file creates and extracts in a wrong directory.  all the extracted files should be moved to the directory created by the first extraction of disc.

    Then, run the Setup file.

  • A clean install of Windows 7 - do not accept keys of the laptop

    I had an older laptop and the hard drive had a mechanical failure.

    I bought and installed a new hard drive and clean installed Windows 7 as downloaded from the Microsoft Web site. The computer is old enough that the manufacturer offers more support for recovery. I installed Windows and I used the key from the sticker on the laptop, and it seemed to accept it.

    However after that I'm getting now pop up windows saying the key is not valid, and I (now) 19 days left to resolve the situation.

    I can't afford to buy a new Windows key - what am I supposed to do?

    The only available ISO images * for the general public * to Windows 7 directly from Microsoft would need to enter your product key to make sure that you download the correct edition.

    I would try to change your product key via the given method, just to be sure and have someone else read the product key for you when you enter.

    If the videos are Flash videos, you have disabled an option in Flash preferences to not allow sites to store Flash cookies on your machine. Made BBC videos in Flash are expecting to be able to store cookies Flash, so videos can not work with this option off Flash.

    Go to Storage Global Flash Settings Panel which serves as Adobe/Macromedia site and check the box «Allow third-party Flash content...» ", where you can then manage the sites you have already visited. You will need to reload the page from the BBC after you change this setting.
