One of the things that you might notice is
that there are a lot of different options for how you can view web pages, and these different options are called
your different browsers. So different browsers have their pros and
cons. I am not one of those people
who get really passionate about having using one over the other. But I will tell you,
as you become a web developer, if you decide to, you're going to want
to know some of these differences. It's perfectly natural to
have a preferred browser, for most people it's whichever one
was installed on their computer. But, when you want to create websites,
you might have one browser you use to look at things, but you really want to
test your site on multiple browsers. So let's talk about some
of the differences. First, we have internet explorer and for
a long time, it was the most popular browser and that was just because it was
the one that came with Microsoft Windows. It was platform-dependent and what that means is that it doesn't
automatically work if you have a Mac. In 2015 Windows 10 came out and instead of
including Internet Explorer as a default, it's using something
called the Microsoft Edge. Edge is meant to replace
Internet Explorer. So people who buy new computers
are going o be using Edge. But don't forget people don't buy new
computers all the time or even if they do buy a new computer, they might decide
they still like Internet Explorer better. So you basely want to make sure that
you're considering both browsers. Another option is Google Chrome. Google Chrome was developed
by surprise Google, and it was a freeware that they created
to be used on Microsoft Windows. However, if data imported or
even consider change. So it works on Linux, your Apple machines, your android, basically most machines
that you're going to come across. The nice thing about Google Chrome is
that they really focused on security. So if that’s something that
you’re kind of concerned about, Chrome is a good way to go. The next option is Firefox. Once again, the theme seems to be,
I’m always recommending free and open source browsers. What open source means is that they've
actually shared their code with everyone for how they created Firefox. And this is a really great way to
let people make suggestions and improvements to it. It's also available for Windows, macOS,
Linux, and BSD operating systems. So who's using the different browsers? Back in 2014,
I can show you that Internet Explorer had a really big chunk of the market,
right around there. You had Internet Explorer 11, Internet
Explorer 10, Internet Explorer 9 etc. So they had the biggest chunk and then Chrome was getting a lot
bigger as well as Firefox. Well, when we look over
here at 2017 though, we can see that Chrome really made a big
surge and up to 64% of desktops and laptops were using Google Chrome followed
by Firefox, Internet Explorer etc. This is all going to change,
its going to flux. You can't pick one browser and say hey, this is the new one that's
everyone is going to be using. And the other interesting thing
to kind of think about is, especially in this old map over here, people use really old browsers because
people like to use what they're used to. One thing that I'm hoping
all the students in my class take into consideration though,
is accessibility. Accessibility is basically
the ability of a browser to support all these special
functionalities, and all these new HTML 5 tags, and
all types of assistive technology. So one place you can go is this
site www.html5accessibility.com. And what you'll find at this site is how well the different
browsers are supporting the text. So you can see right now,
Edge actually has 100% compliance which isn't surprising
because it's one of the newest browsers, so they had accesibility in
mind right from the beginning. The other browsers were created before
people were paying quite as much attention, so they are definitely making
strides to get better and better. However, it is important to notice
that Internet Explorer is at 56% and since it's been basically
relegated to the background, it's unlikely that it's
going to get much better. So what I want you to take away from this
is that browsers can really vary in how well they adhere to different standards. And different versions of browsers
also need to be considered as well. Just because something didn't work in
2018, doesn't mean it won't work in 2019. So the best thing that you can do is write
your code, and then open it up in Safari, and Firefox, and Chrome,
as many different browsers as you can. Not only won't make your sight better, but
it will be a little bit interesting for you as you can look at the different
ways that HTML 5 is supported.
