Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications. With Cascading Style Sheets (CSS) and JavaScript, it forms a triad of cornerstone technologies for the World Wide Web.

Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.

HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as <img /> and <input /> directly introduce content into the page. Other tags such as <p> surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags, but use them to interpret the content of the page.

HTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages. Inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), maintainer of both the HTML and the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.

10 Nutty Facts to Make
You Appreciate Squirrels

By Dani Tinker / National Wildlife Federation
Why exactly is National Squirrel Appreciation Day (January 21) so popular? Maybe it’s because squirrels are adorable, and extremely fun to watch. Maybe it’s the many hats they wear (not real hats — please don’t put hats on squirrels). What I mean is, they play a variety of roles, like acrobat, bandit, gardener, trickster and much more. I set out to discover why these creatures are worthy of their own day, and after you read the facts I found, you might just appreciate squirrels a little more.
Squirrels can find food buried beneath a foot of snow.

Food is important during the cold winter months for squirrels. It makes sense, therefore, that some species are able to smell food under a foot of snow. The squirrel will then dig a tunnel under the snow, following the scent to their (or another squirrel’s) buried treasure
A squirrel’s front teeth never stop growing.

This is a common characteristic of other rodents, as well. The word “rodent” actually derives from the Latin “rodere,” which means to gnaw.
Squirrels may lose 25% of their buried food to thieves.


And that’s just from members of their own species! Scatter hoarders (squirrels with multiple caches of food) have a difficult time keeping an eye on all of their hidden food. Fellow squirrels or birds often take advantage of this for a free meal.
They zigzag to escape predators.

When squirrels feel threatened, they run away in a zigzag pattern. This is an incredibly useful strategy to escape hawks and other predators. Unfortunately, it doesn’t work so well on cars. Consider slowing down and giving squirrels a brake!
Squirrels may pretend to bury a nut to throw off potential thieves.

Squirrels have been observed engaging in “deceptive caching.” This is where a squirrel digs a hole and vigorously covers it up again, but without depositing the nut. It seems this is done to throw off potential food thieves.
A newborn squirrel is about an inch long.

If you come across one of these itty-bitty baby squirrels, please consult these resources, which will advise you what to do. That will help give the baby squirrel its best chance at survival
Humans introduced squirrels to most of our major city parks.

The story about why U.S. parks are full of squirrels is truly fascinating and worth a read.
Squirrels are acrobatic, intelligent and adaptable.

If you’re not convinced, try to hang a bird feeder without these bandits giving you a challenge.
They get bulky to stay warm during the winter.

Putting on some extra weight is one strategy squirrels use to stay warm during the cold winter months.
Squirrels don’t dig up all of their buried nuts, which results in more trees!

They have accidentally contributed countless trees to our nation’s forests. If you ask me, that’s a pretty great reason to appreciate squirrels.

The Earth is the third planet from the Sun and comes between the planet Venus and the planet Mars.
The planets closer to the Sun, Mercury and Venus, have shorter years than the Earth.  The planets further away from the Sun have longer years; Pluto takes 249 of our years to make one orbit of the Sun.
The Earth takes 365 days to complete its orbit round the Sun.  The Earth’s year is therefore 365 days long but the days are added up and every fourth year has one extra day, on the 29th of February.  This fourth year is called a Leap Year (366 days) and is always a year which can be divided exactly by 4 – 2000, 2004, 2008, 2012, 2016.
As the Earth orbits round the Sun it turns on its axis, rotating right round in 24 hours.  The side of the Earth that faces the Sun has daytime and the side of the Earth that is turned away from the Sun has night-time.  When it is daytime in Britain, it is night-time on the opposite side of the Earth in New Zealand.

As the Earth orbits round the Sun it tilts very slightly and so gives us the seasons.  When the Earth has tilted so that the northern half of the Earth is a little away from the Sun, the northern hemisphere (meaning half of the Earth’s sphere) has winter. 

At this time the southern hemisphere is tilted very slightly towards the Sun and the southern hemisphere has summer.  Winter in  Britain means summer in  New Zealand.  Closer to the Equator there is much less difference between summer and winter.
