Join Joseph Lowery for an in-depth discussion in this video Setting up media queries, part of Dreamweaver and WordPress: Core Concepts.
Everyday more and more people visit websites through what used to be alternative devices, tablets and phones. Responsive Web Design is a powerful strategy to handle the problems brought by multiple screen output. In this chapter I'll show you how to set up a major responsive web design component, Media Queries, for your WordPress blog site, for both tablet and phone size screens. This lesson will focus on establishing the media queries properly, as well as a vital Meta tag.
Now before we go any further, I want to show you the power of media queries. So here we are in the blog_comp, and it's showing at a full Desktop size screen. Dreamweaver has some very nice capabilities for quickly shifting to other size screens. Here we see three icons, one is the tablet size that we are going to be working with. So let's go to that and here you see kind of a mini version--the portrait view if you will--of a tablet. And you notice that there was a major change between this and the full-size, mostly it was the content here on the left-hand side which got resized down.
And as we scroll down, you can see that the footer was definitely affected. Smart phone size screens bring in even more radical design choice. So for that we will go to the Window Size list that we see here and choose 320x480 smart phone. And now you see a completely redesigned page that is linearized, it's all in one column, and as I scroll down pass the completely reshaped navigation and missing header graphic, we can see everything is in one column it's very readable, but it's all in one column and then there's a sidebar that follows and a link follows the sidebar.
Now Dreamweaver has a number of ways to automatically create media queries that were used to create these results. But unfortunately, none of them are very helpful under these specific circumstances that we are working with. Luckily, coding media queries by hand is pretty straightforward. So I am going to close out my blog_comp, we won't be needing that anymore at the moment. So I'm here in index.php, and I've used my Custom Filter to narrow the dynamically related files just the ones we will need, which are style.css and header.php. Next, I'll switch to my roux child theme style.css, and then go to the end of the page.
Let's put in about simplest of the media queries to handle our smallest screens. I am going to put in a little comment so that I know that I'm working with the phone, and we will start this rule with a @media restricted to screen. And then start our media query, so after keyword and, open parenthesis max-width: and then the value of the maximum width that we are going to be working with, and that's 320px.
Close the parenthesis, put in a curly brace, put in a couple of lines, and a closing curly brace. So that's a media query for the phone. Now let's do one for the tablet, this one will be for a midsize screen, and we will incorporate one more condition, the minimum width, to set up a range of values for the screen width. So again I am going to do a comment and again, @media screen and (min-width:, and we want this to be just one pixel higher than what our phone's maximum width was.
So 321 pixels, close the parenthesis and then put in another and, and a space. Open parenthesis and put on our other condition. This is another max-width. And we are going to set that to 768 pixels. Again, we will put in an opening curly brace, a line, and then a closing curly brace. So let's save the page. And I am going to stop here. And we will work with these two media queries and the other lessons in this chapter.
You could, and probably should, for a final version of the website you are pushing live, include additional media queries to handle a wider variety of screens. With other media query parameters, you can style your sites for specific orientations and even higher display resolutions, like Apple's Retina Display. For details on how to set up those media queries, check out my lynda.com online training library course, Responsive Design with Dreamweaver CS6.
We've got one more bit of structure to handle, and appropriately enough, it involves a Meta tag. This Meta tag uses the viewport identifier and prohibits the device from automatically scaling down the site so that the Desktop version is reproduced on a smaller screen, which we don't want, because we will be developing custom styles for those screens. We are essentially telling the device, we got this. For this bit of code, we need to access our header section found in header.php.
So I have selected header.php, and let's go into Code view. I am going to scroll down just a little bit. I am going to put my cursor right after the link with the relative pingback and add in our Meta tag, and this is meta with an attribute of name. And the name we are going to pull in is viewport. Dreamweaver's code hints are up-to-date here, so you can just type a v, and then hit Return, and it will fill in the rest and the content attribute takes the initial scale-- initial-scale I should say-- = 1.0.
And then close off the Meta tag, slash and an angle bracket. Okay, I'll save the page, and we are all set. Now you're ready to go after the specific CSS rules to give a custom look and feel for our WordPress blog sites, on both tablets and phones.

Q: While trying to set up a Dreamweaver site, an error occurs that says Dreamweaver cannot resolve the dynamic files because the site definition is incorrect. What is causing this? This is using WAMP on a Windows 7 computer.
A: When setting up the site in Dreamweaver and creating a local testing server, make sure to point it to the folder in c:/wamp/www/ that is being used for the site. If using the same naming convention as shown in the videos, the server folder should be pointing to C:\wamp\www\explore_ca\ and the Web URL field should read http://localhost/explore_ca/, like the picture here:
Q: How do I set the password for WAMP Server 2?
A: The WAMP server does not include a password for MySQL when first installed. You’ll need to add a password by modifying a configuration text file and set up a password in the MySQL server.
Setting a password on the MySQL server:
- From the Start menu, enter CMD to open the command line interface.
- Switch to the bin directory of your MySQL folder, installed by WAMP. For version 5.1.36 of MySQL, for example, enter cd c:\wamp\bin\mysql\mysql5.1.36\bin
Navigate within the WAMP folder installed on your system to find the proper path.
- Enter the following: mysql -u root
- The command line for MySQL will open with a mysql prompt like this: mysql>
- Enter the following:
SET PASSWORD for 'root'@'localhost' = PASSWORD('yourPassword');
- replace 'yourPassword' with the password you want to use.
- Close the CMD window.
After you change the MySQL password you will have to edit the config.inc.php file. Here's how:
- In Windows Explorer, navigate to C:\wamp\apps\phpmyadmin22.214.171.124 (version number may vary).
- Open the file config.inc.php in Dreamweaver or another text editor.
- Locate the following line:
$cfg['Servers'][$i]['password'] = '';
- Enter your password between the quotes; make sure the password is the same as the one you set in the MySQL server.
- Save the file.
- From the system tray icon for WAMP, choose Restart All Services.
- To test, choose phpMyAdmin from the WAMP system tray icon.
Q: After creating a template following the instructions in the Chapter 5 video “Creating a page template in Dreamweaver,” I am unable to select the template. In the video, the instructor’s page shows a heading of Template, with a dropdown menu, but my version shows only a dropdown labeled “Attributes,” and the newly created template does not appear. What is causing this issue?
A: This seems to be a bug in WordPress that occurs occasionally. Although a cause has yet to be determined, a possible workaround to get the Template option to appear is switch themes. Switching to the default theme and then back again to Explore_California should reveal the Template option.
Q: While following along with the instructions in the "Setting up a MySQL password for Windows," I encountered this error: MySQL said: "#1045 – Access denied for user ‘root’@’localhost’ (using password: NO)" What is causing this error?
A: This error occurs when trying to enter the MySQL monitor with a password for a user who has not set a password yet. In that case, removing the “-u root” part should resolve the problem.
Q: While following along to the chapter 2 movie "Using dynamically related files," I get an error message that reads: "Dynamically-related files could not be resolved because the site definition is not correct for this server." What is causing this error?
A: This is a known issue with Dreamweaver, and relates to the permalink settings in the WordPress installation. If the permalink setting is set to something other than the default, like “Month & Name,” for example, Dreamweaver is unable to resolve the dynamic files, and the described error will occur. Changing the permalink setting back to Default will clear the error.
Q: I am bit confused as to my need to use MAMP with a WordPress site in Dreamweaver. If I am going to use a separate commercial hosting site as my server, do I still need to use MAMP in my WordPress site?
A: MAMP is installed to provide an easy-to-use development server capable of handling MySQL and PHP on your local computer. It's also possible to set up MySQL and PHP servers separately, but it requires many more steps and is not as "user-friendly" as the described process. Your hosting server will have MySQL/PHP enabled on their servers for the remote live setup, but that doesn't have anything to do with developing and testing pages on your own computer.
Q: I can't find the file named commevents.php in the exercise files. I need it to set up an online database in the last chapter.
A: This is a file you create yourself when you first connect to a database. Refer to the "Adding WordPress dynamic data to pages" video in Chapter 7. commevents.php should appear in the Connections folder once you establish a connection.
Q: In "Setting up a MySQL password for Windows", I'm getting the error "#1045 - Access denied for user 'root'@'localhost'" when testing the phpMyAdmin.
If I try and re-do the steps, I get the following error "ERROR 1044 (42000): Access denied for user ''@'localhost' to database mysql'" when I try to change the password.
A: This seems to be happening because of the combination of Windows 7 and a
new version of WampServer 2.1. Here's another approach that should work
for the new combination.
Follow these steps instead of the ones using the CMD prompt. (As a bonus, they're much easier!)
- Left-click on the WampServer icon tray.
- Choose phpMyAdmin.
- When the phpMyAdmin page opens in your browser, click the Privileges tab found after the Engines tab.
- Locate the line in the User table with "root - localhost - No..." (probably the last one).
- Click the Edit icon (the final item in the row).
- Scroll down to the Change Password section.
- Select Password and enter your password twice. (If you're following the exercises, enter root).
- Click Go in the lower-right corner.
Q: I want to setup the practice files and site on my localhost, as described; however, I already have my current WordPress site (under development) running on my localhost. How do I run two WordPress sites on my localhost?
A: You can easily do it by setting up another site in Dreamweaver. Just copy the WordPress files to that folder as described and establish a new database via phpMyAdmin. You can set up as many WordPress sites as you need to. The author has upwards of 80 on his system, all for different clients.
Q: This course was updated on 10/23/2012. What changed?
A: The course was thoroughly revised and uses the most current versions of both programs. We added chapters on responsive design and creating a custom administration panel in WordPress, new movies about concepts and taxonomies, and extended the Spry chapter to include jQuery, among other changes. New movies are indicated by the NEW tag next to the movie name.
