Like this Hello World, for
example, is very close to the edge | 3,334.21 | 4.29 |
of this particular div. | 3,338.5 | 1.23 |
It's right up against the
upper left corner of that div. | 3,339.73 | 2.78 |
I might want to change
that by adding what | 3,342.51 | 1.75 |
we might call some padding to this
particular HTML element, some space, | 3,344.26 | 4.17 |
just so that the content
of the element isn't | 3,348.43 | 2.28 |
so close to the border
of the element itself. | 3,350.71 | 3.7 |
So, for example, one thing I can do
is inside this div add some padding. | 3,354.41 | 4.19 |
Say maybe I want 20 pixels worth of
padding on the inside of the element, | 3,358.6 | 4.9 |
such that now when I
refresh the page, we | 3,363.5 | 2.72 |
see that we have some padding
along the outside of the element. | 3,366.22 | 3.22 |
So that Hello World now
shows up not right up | 3,369.44 | 2.33 |
against the edge of the element,
but inside a little bit as well. | 3,371.77 | 4.42 |
And if we have a particular
HTML element that | 3,376.19 | 1.94 |
maybe is too close to
the edge of the screen, | 3,378.13 | 2.13 |
maybe it's too close to
the top of the screen, | 3,380.26 | 2.23 |
we can also add space around
outside of the element | 3,382.49 | 3.17 |
by adding what we call margin
to the element as well. | 3,385.66 | 2.92 |
So I can say let's give it 20
pixels of margin inside of this div. | 3,388.58 | 4.31 |
And then refresh. | 3,392.89 | 1.11 |
And now we see that whereas
before this div was very close | 3,394 | 3.84 |
to the upper left edge
of the screen, now | 3,397.84 | 2.1 |
we've moved it 20 pixels
away from everything. | 3,399.94 | 2.44 |
So it's got some space
on all four sides of it. | 3,402.38 | 3.71 |
So that's how we can now
use margin and padding just | 3,406.09 | 2.95 |
to make the page look a
little bit nicer to the user. | 3,409.04 | 2.21 |
So objects are not too close
together or too far apart. | 3,411.25 | 3.24 |
Padding, again, is on the inside
of the border of the element. | 3,414.49 | 3.57 |
I can add 20 pixels of
padding, for example, | 3,418.06 | 2.65 |
to make sure that the content
inside of the element, | 3,420.71 | 2.4 |
in this case, the words Hello World,
just have a little bit of space | 3,423.11 | 3.35 |
from the border. | 3,426.46 | 0.93 |
And that's padding on the
inside of the element. | 3,427.39 | 2.22 |
Margin, meanwhile, is on
the outside of the element. | 3,429.61 | 2.76 |
We add some margin along the
outside of the border to space | 3,432.37 | 3.06 |
the element out from
other elements that might | 3,435.43 | 2.19 |
be nearby it to make sure that there's
enough space between the border | 3,437.62 | 3.06 |
of the element from the top of
the screen and also from the left | 3,440.68 | 2.74 |
and also the bottom and the right,
though there's no objects there | 3,443.42 | 2.75 |
that we're currently
creating space from. | 3,446.17 | 2.67 |
So by combining width and
height and margin and padding, | 3,448.84 | 3.66 |
we now have the ability,
using CSS, to make sure | 3,452.5 | 3.06 |
that we're able to layout our page
the way we want to lay out the page, | 3,455.56 | 3.05 |
so that elements have the right
amount of spacing from each other | 3,458.61 | 2.71 |
and are the correct size. | 3,461.32 | 2.16 |
So now, let's take a look at some other
features that CSS is going to give us. | 3,463.48 | 3.93 |
In addition to just changing
where particular elements are, | 3,467.41 | 2.94 |
like centering text or adding
size and margin and padding, | 3,470.35 | 3.24 |
we can also use CSS to change
how elements actually look. | 3,473.59 | 3.66 |
We've seen it to change the color
of text, changing it from one color, | 3,477.25 | 3 |
like black, to another color, like blue. | 3,480.25 | 2.49 |
But we can also use CSS to be able
to change something like the font | 3,482.74 | 4.29 |
that we use in order to display text. | 3,487.03 | 2.19 |
Modern web pages don't show
everything in the exact same font. | 3,489.22 | 2.97 |
Usually, some designer
is choosing what font | 3,492.19 | 2.4 |
they want for any particular web page. | 3,494.59 | 3.18 |
So let's experiment with
those possibilities. | 3,497.77 | 2.05 |
I'll now create a new file
that I'll call font.html, | 3,499.82 | 4.4 |
inside of which will be
an HTML page called font. | 3,504.22 | 5.23 |
And inside the body, I'll
again just have a div | 3,509.45 | 2.02 |
that says Hello World, same as before. | 3,511.47 | 3.27 |
But now, inside of the style tag here,
up in the head section of my web page, | 3,514.74 | 4.98 |
I would like to add some
font information to this div. | 3,519.72 | 4.02 |
And in particular, there are a number
of different font-related CSS properties | 3,523.74 | 3.66 |
that I can add to control the font
of any particular HTML element. | 3,527.4 | 4.53 |
One thing I can specify
is the font family, | 3,531.93 | 3.18 |
specifying what font would I like to
use in order to display this text. | 3,535.11 | 4.89 |
And maybe I want to display
it in Arial, for example, | 3,540 | 2.63 |
which is a common font
used on the internet, such | 3,542.63 | 2.92 |
that now if I open up font.html, I now
see in Arial the words Hello World, | 3,545.55 | 6.84 |
different from the text
that I was using before. | 3,552.39 | 3.09 |
You can also specify
multiple different fonts. | 3,555.48 | 2.76 |
Not all computers support all fonts. | 3,558.24 | 1.92 |
So I could specify that just
in case Arial isn't supported, | 3,560.16 | 3.63 |
fall back to any sans serif
font, any of the fonts that | 3,563.79 | 3.57 |
don't have the little glyphs at
the edge of each of the characters. | 3,567.36 | 3.34 |
So now, if I refresh the page,
because my web browser supports Arial, | 3,570.7 | 3.2 |
I don't notice anything different. | 3,573.9 | 1.44 |
But you might imagine if you're using
more complex fonts that not all web | 3,575.34 | 3.04 |
browsers have or support, you
might add some backups just | 3,578.38 | 2.78 |
in case the font you want
isn't actually available. | 3,581.16 | 3.81 |
In addition to a font
family, I might also | 3,584.97 | 2.01 |
specify a font size, how big I want
the font to be inside of this div. | 3,586.98 | 4.33 |
So I can specify that I'd like the
font size of this give to be, you know, | 3,591.31 | 3.6 |
28 pixels, for example,
such that now I refresh it. | 3,594.91 | 3.23 |
And now, this div appears
using larger text. | 3,598.14 | 3.48 |
And I can also, just
as like text editors | 3,601.62 | 2.22 |
let you specify whether you want it
to be normal text or bolded text, | 3,603.84 | 3.81 |
I can specify a font
weight for this div and say | 3,607.65 | 3.51 |
that in addition to being
in font Arial in size 28, | 3,611.16 | 2.97 |
I would also like for the font to
be bold, such that now I refresh it, | 3,614.13 | 3.96 |
and now, the font shows up as bold. | 3,618.09 | 2.73 |
And using these CSS style sheets,
we're able to selectively apply | 3,620.82 | 3.57 |
the styling to only particular
parts of the web page. | 3,624.39 | 3.48 |
If I have another underneath this div
some more text down here, for example, | 3,627.87 | 5.16 |
that additional text
that's outside of the div | 3,633.03 | 2.73 |
isn't going to be affected
by the CSS styling, such | 3,635.76 | 3.12 |
that now if I refresh this
page or some more text | 3,638.88 | 2.64 |
shows up in that same standard default
font provided by my web browser and not | 3,641.52 | 4.92 |
the custom font that I have
specified to apply to only | 3,646.44 | 3.06 |
