How did it go?
0:00
You had to use a lot of different front
end skills to solve this challenge.
0:01
Not only did you need to use JavaScript,
but you needed to understand HTML and CSS.
0:05
If you managed to complete all
of those tasks, good for you.
0:09
You've got a good grasp
of front end development.
0:13
If you couldn't figure them all out,
that's okay.
0:17
You just need to practice more.
0:19
Let me show you how I
solved this challenge.
0:21
Let's start with the HTML.
0:24
We need to figure out how
to target the HTML for
0:27
the want us to work on your project text.
0:30
Okay, here it is.
0:34
It's an h5 tag.
0:34
That's a bit too generic to use since
there are other h5 tags on this page and
0:36
we want to just stick this one.
0:41
Let's add a class so
we can identify this tag with our code.
0:44
We'll use this work code for the selector.
0:49
I'll open the main.js file.
0:52
Even though this effect will
only apply to a single page,
0:56
the work.html file, I'm still going
to add the code to the main.js file.
0:59
This is just to keep my
JavaScript code in one place.
1:04
However, if I was going to add hundreds
of lines of code that only applied to
1:08
the work.html file, I would add that
code directly into the webpage but,
1:11
because I'm only adding
a few lines of code,
1:17
there's no real performance problem
loading this code in other pages.
1:19
Okay, let's select that block of
text then we call the sticky plugin.
1:24
I'm gonna save the file then preview it.
1:31
As you can see,
it doesn't work that well yet.
1:40
The, want us to work on our project text,
sits on top of the navigation bar.
1:43
We can pass an object
when we call the plugin,
1:49
that changes the position
of this block of text.
1:51
Where did the number 60 come from?
1:58
You know, I just tried a bunch of
numbers until I found one that worked.
2:00
Let's check it out.
2:04
I'll save the files and
preview the work space.
2:05
We're getting there, but you can see
content pass underneath the text.
2:09
It would look better if
it had a solid color.
2:14
We can do that using CSS.
2:16
I'll open the main .CSS file and
add a new style.
2:20
Remember that the sticky.js plugin adds
the is-sticky class when an element is
2:32
stuck to the top of the browser window.
2:37
This style gives the text block
a white background color, and
2:40
a few other properties that control
the spacing inside and around the block.
2:44
Again, those are settings I had to
experiment with to get them to work.
2:49
Now let's add that email
link to the end of the text,
2:54
want us to work on your project.
2:57
To do that, we need to add an event
handler for the sticky-start event.
3:00
So I'll select the h5 tag again and
3:05
use jQuery's on method to apply a callback
function to the sticky-start event.
3:07
Whatever I place inside the braces
will run when this text block sticks.
3:18
In this case, I want to add
an email link after the text.
3:23
I can do that with jQueries append method.
3:27
The ${this} refers to
the element that the applies to.
3:37
In this case it's the h5 tag with the
text, want us to work on your project?.
3:41
If you're not familiar with
either jQuery's append method or
3:47
the this keyword, look in the teacher's
notes for more information.
3:50
Now jQuery's append method adds
HTML to the end of the selection.
3:55
In this case,
it adds a link to the end of the h5 tag.
3:58
The link has the class email text.
4:01
We can use that class as a handle for
selecting and
4:07
then removing the email link
when the text block unsticks.
4:10
We do that using the sticky-end event.
4:14
This code simply selects an element
with the class email text and
4:24
removes it from the page.
4:28
Let's see how it works.
4:31
I'll save the files and
preview the work space.
4:33
Okay, this looks good.
4:40
There's one last thing I want to show you.
4:42
If you re-size the browser window
while the elements are stuck,
4:44
things get a little weird.
4:48
Notice that those stuck
elements don't re-size either.
4:50
Fortunately, the plug in can handle and
4:53
dynamically update the fixed elements
when the browser is re-sized.
4:55
To do that,
you provide to options to the plug in.
5:00
The first,
is the get width from property, and
5:04
it tells the plug in which element
determines the width of the fixed element.
5:07
This is usually some other tag
that wraps around that element.
5:11
It could be the body tag, or simply a div.
5:14
Let's look at the HTML.
5:17
Notice that there's a div here.
5:19
It has a few classes on it,
including the container class.
5:21
This was added to the tag to indicate that
it contains all the content on the page.
5:25
We can use that to get the width.
5:30
Now the value must be a string and
it should be a CSS selector.
5:37
Next you set the responsive
width property to true.
5:43
This just tells the sticky.js plugin that
it should respond to changes in the width
5:49
of the browser window.
5:54
I now need to add this for
the other call to the sticky plugin here.
5:56
Let's see how it works.
6:10
I'll save the file and
preview the work space.
6:11
Excellent.
6:24
Congratulations, you've learned
how to use another jQuery plugin.
6:29
As I mentioned at the beginning of this
course, many plugins you'll run into,
6:33
even ones that add wildly
different features to a website,
6:36
are added to a page in a similar manner.
6:40
In other words,
at this point you'll be able to find and
6:42
add many different plugins
without much trouble.
6:46
And we've got one last section of
this course, and it's a good one.
6:49
In it, you'll learn how to add a carousel,
a kind of slideshow to a webpage.
6:52
It's an eye-catching way to include
a lot of content on a page.
6:56
It is often used on a site's homepage
to showcase different content,
7:01
or sections of a site.
