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.
