So, in the last module we started looking
at CSS, which is Cascading Style Sheets,
-
and why is it important to separate
styling from the content when you're
-
doing web design and development.
And in this particular week, you will
-
continue learning CSS, but we move in,
we move further from basic styling to
-
more layout and positioning.
And this is your chance to really
-
get to learn CSS well and make sure
that you have mastered CSS enough
-
to be able to use in the websites
that you develop for this course.
-
And the other topic that we cover
this week is graphics and media,
-
so we get familiar with various kinds
of media formats, like JPEG, GIF, PNG,
-
TIFF, and so on, and it is very important
to know which media formats to use when,
-
and how do the quality components matter
in terms of how they impact file sizes,
-
because if the file sizes are too large,
then they won't load effectively on the
-
computers of people who might have slow
internet connections, and also it is good
-
to be able to be familiar with any sort of
photo manipulation software,
-
like GIMP, or Adobe Creative Suite,
and so on, so that you can manipulate
-
the images in an effective manner when
you want to use them in your web pages.
