Learn the basics of building complex, data-driven applications with the Facebook PHP SDK and MySQL. Author Ray Villalobos first introduces the fundamentals, such as checking to see if a user is logged into an application, accessing Facebook user data through the Open Graph API, and making complex API calls with the Graph API Explorer. The course then dives into building an application with API paths and Facebook Query Language (FQL) calls. Along the way, you'll discover how to post to a user's wall, upload photos, integrate with webpages, and more.
So our navigation at the bottom of our page is working very well, but it doesn't look great and is a little bit hard to use since these numbers are so close together, so let's take a look. I have a live preview of my application on the right-hand side and the CSS on the left. I'm going to scroll all the way down to the end of the CSS, and I'm just going to add a few classes here. So I have a paging section and to that I'm going to add a little bit of padding, just 10 pixels, that just moves everything a little bit to the right. And then I'm going to align the text to the center, so it moves everything to the center.
Then I'm going to take the page navigation, which is just the numbers, and I'm going to add a border at the top and make that border dotted and just leave it at 333. Plus, I'm going to add a little bit of padding just at the top and bottom and not on each side. Then I'm going to do the numbers, so I'll take the paging and then the number class and target the anchor tags in there. And inside the anchor tags I'm going to add a little bit of padding just to either side, that gives us a little bit more breathing room right here.
I'm going to modify the links or the text- decoration to be none, so the inside numbers in between the previous and the next links are not going to have underlines, even though the next link will. And finally, I'm going to add a little bit of style to the current number. So the links that are styled with an extra class of current, that should be the current number, are going to get a little bit of a different style, so I'll style them as inline-blocks, color them white.
I need to make sure that these are together like that, since they're part of the same class. I'm going to modify this item to be an inline block, that way I can control the width and the padding, as well as have a white color. And then I'll give it a background color that's going to be the red that I'm using in other places. That looks pretty good. And I'm going to add a little bit of a border radius.
That makes the current page be a circular dot of that color, which I think looks really nice. And I'm going to add the prefixes for Mozilla and just the regular border-radius prefix. When I give that number that red background, it actually looks like that number is a little bit closer to the number 2. So I'm going to add a little bit of a margin of nothing at the top and bottom and 5 pixels on each side just to give it a little bit more breathing room so that it displays nicely.
And that's pretty much it. I'm going to Save this, and I'll hit the 2 link right here, and if I go to the bottom, you can see that that's showing up pretty well, the previous link works well, and the next link looks really good, everything is center, and that looks really good. With just a few lines of code we've made our navigation look great. So if you want to learn more about CSS, make sure you check out the online training library for courses like CSS Page Layouts.
