WGU D276 WEB DEVELOPMENT FOUNDATIONS 100% SOLVED Action Attribute (attribute of form element) defines the action to be performed when the form is submitted Target Attribute (attribute of form element) specifies where to display the response that is received after submitting the form _blank (a Target Attribute value) The response is displayed in a new window or tab _self (a Target Attribute value) The response is displayed in the current window _parent (a Target Attribute value) The response is displayed in the parent frame _top (a Target Attribute value) The response id displayed in the full body of the window framename (a Target Attribute value) The response is displayed in a named iframe Method Attribute (attribute of form element) specifies the HTTP method to be used when submitting the form data GET (HTTP Method for Method Attribute) -Appends the form data to the URL, in name/value pairs -NEVER use GET to send sensitive data! (the submitted form data is visible in the URL!) -The length of a URL is limited (2048 characters) -Useful for form submissions where a user wants to bookmark the result -GET is good for non-secure data, like query strings in Google POST (HTTP Method for Method Attribute) - Appends the form data inside the body of the HTTP request (the submitted form data is not shown in the URL) - POST has no size limitations, and can be used to send large amounts of data. - Form submissions with POST cannot be bookmarked Autocomplete Attribute (attribute of form element) specifies whether a form should have autocomplete on or off. When autocomplete is on, the browser automatically complete values based on values that user has enter before Novalidate Attribute (attribute of form element) When present, it specifies that the form-data (input) should not be validated when submitted Document Object Model (DOM) is a programming API for HTML and XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated Elements (part of Chrome Developer Tools) shows you the HTML used to build the page you're looking at, together with any inline CSS Console (part of Chrome Developer Tools) deals with JavaScript. It gives you information about interactive elements on a page. In Console, you can write JavaScript to interact with the web page you're viewing, and it also lets you write messages to yourself in the JavaScript of websites you're building, which then show up in Console to show that the JS was executed Sources (part of Chrome Developer Tools) shows where all the files that were used to make the website are stored and lets you inspect them Network (part of Chrome Developer Tools) shows you all the files that are loading in the URL you're looking at Application (part of Chrome Developer Tools) shows what's in your browser storage: in-browser databases like Web SQL, local storage, and more. It also gives you granular control over your cookies Security (part of Chrome Developer Tools) gives you basic security information, letting you view a site's HTTPS certificate and TLS status Bootstrap is one of the most popular free, open-source frameworks. It uses HTML, CSS and JavaScript to help a developer create responsive websites Bootstrap components Icons and Typography Responsive design is the main usage of Bootstrap. Using grids, columns, and containers helps the web developer create responsive pages video element video HTML5 element used to insert video onto a webpage source Element used to specify a media resource controls Attribute that allows the user to play, pause, and adjust audio settings src Attribute used within the source tag to specify the media file type Attribute used within the source tag to specify the type of video (mp4, webm, ogg) audio element audio HTML5 element used to insert audio onto a webpage source Element used to specify a media resource controls Attribute that allows the user to play, pause, and adjust audio settings src Attribute used within the source tag to specify the media file type Attribute used within the source tag to specify the type of audio (mp3, wav, ogg) iframe element is used to embed a document hosted on another domain, such as YouTube or Google Maps. An iframe displays a webpage within a webpage Vector Graphics that use mathematical coordinates with lines, curves, and shapes to create images and specify colors Bitmap graphics that use small dots (usually thousands) to create images and specify colors Image Transparency Web-ready image file formats that support transparency are GIF, PNG and SVG. JPEG, BMP and TIFF formats do not support transpaency on the Web Scalable Vector Graphics (SVG) is a W3C-recommended language developed by various vendors including Adobe, Microsoft and sun. SVG uses XML to describe graphics and graphical applications. SVG allows you to create cross-platform animated movies Image Map (Hot Spot) an image that includes hyperlinks within specific areas of the image. These linked areas or hotspots, are defined by a set of coordinates Simple selectors select elements based on name, id, class Combinator Selectors select elements based on a specific relationship between them Pseudo-class Selectors select elements based on a certain state Pseudo-elements selectors select and style a part of an element Attribute Selectors select elements based on an attribute or attribute value #id Example: #firstname Example description: Selects the element with id= "first name" .class Example: .intro Example description: selects all elements with class="intro" Example: Example description: Selects only p elements with class="intro" * Example: * Example: Selects all elements element Example: p Example: Selects all p elements element, element Example: div, p Example: Selects all d elements and all p elements Descendant selector (space) matches all elements that are descendants of a specified elements Child selector () selects all elements that are the children of a specified element Adjacent sibling selector (+) is used to select an element that is directly after another specific element General Sibling Selector (~) selects all elements that are next siblings of a specified element Equal Specificity the latest rule wins- If the same rule is written twice into the external style sheet, then the latest rule wins ID selector have ____ specificity than attribute selectors higher Contextual selectors are more specific than a single element selector The embedded style sheet is closer to the element to be styled A class selector beats any number of element selectors a class selector such as .intro beats h1, p, div, etc The universal selector (*) and inherited values have a specificity of 0 The universal selector (*) and inherited values are ignored ordered list tag type="1" Numbers (default) type="A" Uppercase letters type="a" Lowercase letters type="I" Uppercase Roman numerals type="i" Lowercase Roman numerals tr create a table row, which contains all the row's cells th create a new table cell containing table header information about the data. Usually the browser displays table headers centered with a bold font td opening and closing tags create a new table cell containing a table datum XML a markup language that you can use to structure and format any kind of data that have multiple purposes such as the following: Data storage Data retrieval Data mining Data processing, which may include content that will display on a web page XML Prolog ?xml version="1.0" encoding="UTF-8"? All XML elements must have a ___ tag closing ____ tags are case sensitive XML ____ Elements must be properly nested within each other XML XML Attribute Values must always be ____ Quoted Entity Reference If you place a character like "". inside an element, it will generate an error because the parser interprets it as the start of a new element. to avoid this error, replace the "" with an entity reference There are 5 pre-defined entity references in XML: less than greater than & & ampersand ' ' apostrophe " " quotation mark White space is preserved in XML XML does not truncate multiple white-spaces (HTML truncates multiple white-spaces to one single white-space) An XML Element can contain Text Atributes Other Elements Or a mix of the above Empty XML Elements An element with no content is said to be empty. In XML, you can indicate an empty element like this: element/element You can also use a so called self closing tag: element/ XML Naming Rules Element names are case-sensitive Must start with a letter or underscore Cannot start with the letters xml can contain letters, digits, hyphens, underscores, and periods, cannot contain spaces XML Elements are Extensible XML elements can be extended to carry more information If the padding property has 4 values they cover top, right, bottom, left If padding property has 3 values they cover top, left and right, bottom If padding property has 2 values they cover top and bottom, and left and right If padding property has 1 value it is assigned to all 4 sides @keyframes rule the animation will gradually change from the current style to the new style at certain times animation-duration property defines how long an animation should take to complete. If the animation-duration property is not specified, no animation will occur animation-delay property specifies a delay for the start of an animation animation-iteration-count property specifies the number of times an animation should run animation-direction property specifies whether an animation should be played forwards, backwards or in alternate cycles Normal (animation-direction property) The animation is played as normal (forwards). this is default Reverse (animation-direction property) The animation is played in reverse direction (backwards) Alternate (animation-direction property) The animation is played forwards first, then backwards Alternate-reverse (animation-direction property) The animation is played backwards first, then forwards Animation-fill mode property specifies a style for the target element when the animation is not playing none (Animation-fill mode property) Default value. Animation will not apply any styles to the element before or after it is executing forwards (Animation-fill mode property) The element will retain the style values that is set by the last keyframe (depends on animation-direction and animation-iteration-count) backwards (Animation-fill mode property) The element will get the style values that is set by the first keyframe (depends on animation-direction), and retain this during the animation-delay period both (Animation-fill mode property) The animation will follow the rules for both forwards and backwards, extending the animation properties in both directions. W3C CSS Validation Service can bused to check the correctness (validity) of CSS
