Multiple Background Images

Transcript: The last background image will be the bottom layer. Beware of trying to cram in too many overlapping images. All of the normal background image properties apply, they are just separated by commas. Background Properties background-image: url(image1.png), url(image2.jpg); background-size: 25%, cover; background-repeat: no-repeat, no-repeat; background-position: 50% 75%, center; Layered Images Here image1 will be on the top layer, while image3 will be the bottom layer. Remember, transparencies are only supported with certain image formats. You can overlay as many background images as you want, but remember that backgrounds affect visibility of site content. Background images can add variety and help make your page stand out. For example, in this presentation, the flying origami birds are the background image. Sometimes one background image isn't enough. Fortunately, CSS allows us to layer multiple background images. The first background image listed will be the first layer, followed by the second, etc. Below is a basic example of layered background images. Adding Multiple Backgrounds div { background: url(image1.png), url(image2.png), url(image3.png); } Multiple Background Images Adding multiple backgrounds is easy. Just add the next image in the same way you would a background image, separated by a comma. Multiple Background Images Be careful not to put opaque images on top or you won't see the the other layers. div { background: url(image1.png), url(image2.png), url(image3.png); } Sample Page For example:

Transcript: Galaxy Presentation by Dylan Kha and Johnny Ni Milky Way Stars and Galaxies Solar System Stars and Galaxies Galaxies Galaxies A galaxy is a cluster of millions and billions of stars, dust, and gas all held together by gravity. There is possibly a black hole is in the center of a galaxy. Irregular Galaxies An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. They are among the smallest galaxies and are full of gas and dust. Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. This can make them very bright. The Large and Small Magellanic Clouds are examples of irregular galaxies. They are two small galaxies which orbit around our own Milky Way Galaxy. About 20% of all galaxies are irregulars. Spiral Galaxies A spiral galaxy is flat with a bulge in the middle which is usually a black hole. It is called a spiral galaxy because of its arms that rotate around the center black hole. Our galaxy is the Milky Way, which is a spiral galaxy, which includes millions of stars even bigger than our sun. Elliptical Galaxies Galaxies come in many shapes and sizes. Among the largest are the “elliptical galaxies”, massive ball-shaped galaxies made up of trillions stars. The densest regions of the universe provide perfect conditions for growing elliptical galaxies. In rich clusters, galactic collisions are common. The largest galaxies pull in many smaller ones and build themselves by cannibalizing their neighbors. In dense galactic clusters, like the Coma Cluster located nearly 300 million light-years from Earth, the majority of galaxies are elliptical galaxies. In this cluster, they have all congregated towards the cluster’s center leaving the remaining spiral galaxies out towards the edges. Facts about galaxies Elliptical galaxies contain some of the oldest stars because they do not have the ability to form new stars. Elliptical galaxies are so bright that if Earth were located inside of one, there would always be day light everywhere no matter the time of day. A lot of irregular galaxies probably began as an elliptical or spiral galaxy that crashed into another galaxy. From the southern hemisphere of Earth, two other galaxies can be seen with the naked eye. A small galaxy is one that contains less than a billion stars. Stars Solar System Stars are is a large ball of burning gas in space. Stars appear to us as small points of light in the sky on clear nights. The central core of a star is extremely hot and produces energy by fusion, the fusing of elements usually hydrogen in this case. Some of this energy is released as visible light, which makes the star glow. Our sun, the center of our solar system, is a yellow star of average temperature and size. Facts about stars Stars that are blue are typically much hotter than the average star. At the most conservative estimate, there are at least 10 billion trillion stars in the universe. Stars are formed from dense knots contained in large clouds of dust and gas called nebulae. One in four Americans believe that the sun orbits the Earth, rather than the other way around. Every day, approximately 275 million new stars are formed in the universe. Thank you for watching!

Background Images

Transcript: Placing a background image requires more than just using the background-image property. There are other properties that you will need to familiarize yourself with in order to successfully place your image on your web page. These background CSS properties include: background-color Sets the background color of an element. background-image Sets the background image for an element. background-repeat Sets how a background image will be repeated. background-attachment Sets whether a background image is fixed or scrolls with the rest of the page. background-position Sets the starting position of a background image. See the examples on the next slides. Background Images Let's put it all the properties together. body{ background-color: #333; background-image: url(../image/mountain.png); background-repeat: no-repeat; background-attachment: fixed; background-position: top left; } According to w3schools.org the order of the properties matter. You don't need each of the properties or in other words one or more of the items can be missing. However, it should maintain the same order. To help me remember, I think of pancakes. Because pancakes need syrup. In this case, the background order needs CIRAP. Color, Image, Repeat, Attachment and Position. When adding a background image to your website, it is important to understand what file types work the best to improve your download speed. Example of file types for background images: .png .jpg .gif Tip - In order to change a photo file type like a .jpg, .pdf or .eps file to a .png file on a Mac, open the file in Preview. Then on the file menu and choose export. Near the bottom of the menu click format and select .png and then click on save. It's that easy. Background Properties Adding a Background Image http://www.w3schools.com/cssref/pr_background-image.asp The background-image property sets one or more background images for an element. The background of an element is the total size of the element, including padding and border (but not the margin). By default, a background-image is placed at the top-left corner of an element, and repeated both vertically and horizontally. Background Fixed Image Despite your decision to use a background image, it's still recommended that you use a background color as a default. body{ background-color: #333; background-image: url(../image/mountain.png); background-repeat: no-repeat; } The reasoning behind the additional use of background color, is in case the browser does not load for your user. That said, make sure you choose your default color wisely. You don't want a neon color to blow your user experience away and distract them from your content or product. (unless you want to bring back the 80's to your site) A background image added to a website with no content. body{ background-image: url(../image/mountain.png); background-repeat: no-repeat; } Background Image Color Background Image Repeat Background Images Conclusion Background Images Background Image File Types When the background is fixed, the text on your page scrolls while the background does not move. The last item I want to discuss is background positioning. This property will set the starting position of the background image. For example, the standard starting position is the top left of a website here in the U.S. because our language is read from left to right. In countries that read from right to left a positioning that would work best would be top right. body{ background-image: url(../image/mountain.png); background-repeat: no-repeat; background-attachment: fixed; background-position: top left; } Background Image Positioning Putting It All Together body{ background-image: url(../image/mountain.png); background-repeat: repeat; } Background Images are an impactful aspect or your web page design. Learning how to apply a background-color as a default and placing and background-image within your body div in your CSS file are the first two key steps. Depending on what type of image you have will then help you to decide whether or not you will need to utilize the other background properties. The additional properties are background-repeat, background-attachment and background-position. Lastly, remember when dealing with background properties, don't forget to pass the CIRAP. In order to add a background image to your site, you need to apply the background-image property to your <body> tag in your CSS file. Example code: body{ background-image: url(../image/mountain.png); } The url destination is mapped to the location of the file image through the direct path in the folder structure. The majority of websites use some form of a background image to enhance their user experience. Some sites choose to use simple backgrounds like apple.com. Other sites like msn.com use only a color for their background, leveraging white space to to highlight their content. body{ background-image: url(../image/mountain.png); background-repeat: no-repeat; background-attachment: fixed; } Background Image No

Galaxy Presentation

Transcript: By Nolan Srebnick, Nina Marganti Galaxy Presentation The blue in the picture shows infrared light with wavelengths of 3.6 micron, the green represents 4.5 micron light and red, 8.0 micron light To enhance the invisibility of the dust features the starlight (3.6 microns) is subtracted from the 8 micron image Sunflower galaxy Sunflower Galaxy The Sunflower Galaxy is located in the constellation Canes Venatici. The Rotational Curves for this galaxy are currently unknown. Where is this galaxy? Other info Like the Whirlpool galaxy, the M63/Sunflower galaxy was one of the first spiral galaxies to be discovered. The galaxy is part of the M51 group of galaxies, with the M standing for Messier, after it’s discoverer. The M in the M63 also stands for Messier. M63/Sunflower galaxy is quite a compact galaxy within it’s structure, and while it has spiral arm features, they are not widely noticeable until the galaxy is studied in further depth. Hence the name Sunflower galaxy, as the spiral galaxy resembles a Sunflower. Fun Facts Fun Facts Galaxies are divided into 5 different groups in Hubble's classification such as elliptical, lenticular or S0, spiral, barred spiral, and irregular The Sunflower galaxy is classified as SA (rs)bc spiral galaxy Hubble galaxy classification system More info The Sunflower galaxy is 37 million light years from Earth The mass is 10 billion solar masses The diameter of about 60,000 light years, just a fraction of the size of the Milky Way Composed of dust and gas Distance, size, mass Info Has the physical form of a radio galaxy which means it's very luminous at radio wavelengths M49 M49 M49 is located in the constellation Virgo. The Rotational Curves for this galaxy are currently unknown. Where is this galaxy? Other Info Messier 49 was only the second galaxy discovered outside the Local Group, after Messier 83. M49 is also more luminous than any of the galaxies lying closer to Earth. Messier 49 contains a large number of globular clusters, estimated at 5,900. The globulars detected in M49 have an average age of about 10 billion years. Fun Facts Fun Facts About 56 million light-years away in the equatorial constellation of Virgo The mass is 565 million times the mass of the Sun Diameter of about 170,000 light years or size of 10x8 arc minutes Classification- E4, elliptical galaxy Galaxy appears small and diffuse with a bright compressed central core Distance, mass, size, composition, classification Other info Combines a wide range of wavelengths spanning the ultraviolet, optical, and infrared parts of the spectrum. IC 559 IC 559 ic 559 is located in the constellation Leo. The Rotational Curves for this galaxy are currently unknown. Where is this galaxy? Other Info Discovered in 1893, IC 559 lacks the symmetrical spiral appearance of some of its galactic peers and not does not conform to a regular shape. IC 559 may have once been a conventional spiral galaxy that was then distorted and twisted by the gravity of a nearby cosmic companion. Fun Facts Fun Facts Makes up a quarter of all known galaxies Does not fall into any regular classes of the Hubble classification system Sm galaxy, irregular galaxy (with evidence of a spiral structure) Full of gas and dust which is spawning new stars Mass- unknown Size, mass, distance, composition, classification Other info https://www.messier-objects.com/messier-63-sunflower-galaxy/ https://www.nasa.gov/mission_pages/spitzer/multimedia/m63-irac.html https://www.ouruniverseforkids.com/m63-sunflower-galaxy/ https://www.messier-objects.com/messier-49/ https://www.nasa.gov/content/goddard/hubble-paints-a-spattering-of-blue https://dept.astro.lsa.umich.edu/resources/ugactivities/Labs/GalClass/GalClass.html http://www.messier.seds.org/Pics/More/m49a.jpg https://freestarcharts.com/messier-63 https://www.constellation-guide.com/sunflower-galaxy-messier-63/ http://www.stardoctor.org/M63.html https://en.wikipedia.org/wiki/Messier_49 https://freestarcharts.com/messier-49 https://www.messier-objects.com/messier-49/ https://www.nasa.gov/content/goddard/hubble-paints-a-spattering-of-blue Sources Sources
