Within CSS, element backgrounds can be a solid color, an image, a gradient, or a combination of these. As we decide how to implement these backgrounds, we should keep in mind that every background contributes to the overall appearance of our website. Adding a Background Color The quickest way to add a background to an element is to add a single-color background using the background or background-color property.
The background property accepts colors and images in shorthand form, while the background-color property is used strictly for setting solid background colors. If Internet Explorer 8 support is a concern, fortunately there is an easy way to provide a fallback background.
CSS cascades from the top of a file to the bottom of a file; thus, we can use two background-color properties within a single rule set.
Background images work similarly to background colors; however, they offer a few additional properties to finesse the images. As before, we can use the background property with a shorthand value, or we can use the background-image property outright. No matter which property we use, there must be an image source identified using a url function.
Keep an eye out for different directories, and be sure to show exactly where the image resides. The path will be placed inside parentheses and quoted. Thankfully we can use the background-repeat and background-position properties to control how or even whether the image repeats.
Background Repeat By default, a background image will repeat indefinitely, both vertically and horizontally, unless otherwise specified. The background-repeat property may be used to change the direction in which a background image is repeated, if repeated at all.
The repeat value is the default value and will repeat a background image both vertically and horizontally. The repeat-x value will repeat the background image horizontally, while the repeat-y value will repeat the background image vertically.
Lastly, the no-repeat value will tell the browser to display the background image once—that is, do not repeat it at all. Background Position By default, background images are positioned at the left top corner of an element. However, by using the background-position property, we can control exactly where the background image is placed relative to that corner.

(How to Write a (Lisp) Interpreter (in Python)) This page has two purposes: to describe how to implement computer language interpreters in general, and in particular to build an interpreter for most of the Scheme dialect of Lisp using Python 3 as the implementation language. I call my language and interpreter Lispy ().Years ago, I showed how to write a semi-practical Scheme interpreter Java. Code Autodetection Notice! You have selected., however your code looks like Click on Change to use the new Code Type and continue, Ignore to continue compression without changing the Code Type, or Cancel to abort so you can manually change your selection and adjust other settings.. Note: you can turn off autodetection in Options > Misc Options.
To set a background-position value, we can use the top, right, bottom, left, and center keywords, pixels, percentages, or any length measurement. Keywords and percentages work very similarly. The keyword value left top is identical to the percentage value 0 0, which will keep an image positioned at the left top corner of the element.
Fig 7 Background images are positioned from the left top corner of an element Using pixels for a background-position value is also common, as pixels give us precise control over where our background will be positioned.
Shorthand Background Image Values The background-color, background-image, background-position, and background-repeat properties may be rolled up into a shorthand value for the background property alone. The order of these properties as a shorthand background property value may vary, however it commonly falls as background-color, background-image, background-position, and then background-repeat.
Please take note that there is both a relative value and an absolute value within the background-position value. The first value, 20 pixels, is the horizontal value, positioning the background-image 20 pixels from the left of the element.
A few other properties and values are also included within the notice-success class rule set to further style the alert message. Congratulations, you did it!
