Sneaker is a synonym for “athletic shoes,” the generic name for the footwear primarily designed for sports or other forms of physical exercise. Additionally, sneakers have come to be used for casual everyday activities. The term describes a type of footwear with a flexible sole made of rubber or synthetic material and an upper part made of leather or canvas. Examples include athletic footwear such as: basketball shoes, tennis shoes, cross trainers and other shoes worn for specific sports.
Sneakers is the more common term used in northeastern United States and southern Florida. The British English equivalent of “sneaker” in its modern form is “trainer”. In some urban areas in the United States, the slang for sneakers is kicks. In Hiberno-English, Canadian English and Australian English the term is runners or sneakers or running shoes. In South African English the term used is takkies.
Bass (/ˈbeɪs/ bayss) describes musical instruments that produce tones in the low-pitched range. They belong to different families of instruments and can cover a wide range of musical roles. Since producing low pitches usually requires a long air column or string, the string and wind bass instruments are usually the largest instruments in their families or instrument classes.
In the modern world, bags are ubiquitous, with many people routinely carrying a wide variety of them in the form of cloth or leather briefcases, handbags, and backpacks, and with bags made from more disposable materials such as paper or plastic being used for shopping, and to carry home groceries. A bag may be closable by a zipper, snap fastener, etc., or simply by folding (e.g. in the case of a paper bag). Sometimes a money bag or travel bag has a lock. The bag likely predates the inflexible variant, the basket, and bags usually have the additional advantage over baskets of being fold-able or otherwise compressible to smaller sizes. On the other hand, baskets, being made of more rigid material, may better protect their contents.
Responsive web design (RWD) is an approach to web design aimed at crafting sites to provide an optimal viewing and interaction experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from desktop computer monitors to mobile phones).
A site designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids, flexible images, and CSS3 media queries, an extension of the @media rule, in the following ways:
The fluid grid concept calls for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points.
Flexible images are also sized in relative units, so as to prevent them from displaying outside their containing element.
Media queries allow the page to use different CSS style rules based on characteristics of the device the site is being displayed on, most commonly the width of the browser.
Responsive web design is becoming more important as the amount of mobile traffic now accounts for more than half of total internet traffic. This trend is so prevalent that Google has begun to boost the ratings of sites that are mobile friendly if the search was made from a mobile device. This has the net effect of penalizing sites that are not mobile friendly.
