CSS 3 Margins Divs
VISA/APCO/STAC 2P61 WEBSITE CREATION Fall Term 2012 __________________________________________________________________________________ CSS 3 - LAYOUT BASICS A FUNDAMENTAL CONCEPT – WHAT IS MEANT BY CASCADING The cascade is how CSS resolves conflicts when more than one rule is applied to the same element 4 style sheets applying: Internal styles External styles sheet Internal styles Browserʼs default style sheet Inline will beat out all – WHY? It is lowest in the cascade. Order of CSS rules is important The later a rule appears in a style sheet the more weight it is given MARGINS, BORDERS, PADDING See Ch. 10 – Web Standardistas Book About spacing – the space around our elements The effect the relationship of one element to another. The all important BOX MODEL All elements treated as boxes. Some are block-level Some are inline-level Each box is comprised of a content area and optional margins, borders and padding Up to now these have all be set by the Browserʼs default style all these can be specified The width of an element includes all – e.g. Margin-left + border-left + padding left – element width + padding-right + border-right + margin right Applying margins borders and padding See short html page in Ch. 10 First pass – no margins – fits to left edge of page Second pass - add background colour so we can see the block-level paragraph element Third pass - Before we add margins we must remove margins set by the browserʼs default style sheet. Set margin on body and on p to margin: 0; Once this is done you can add margin: 40 px; This sets margin on all four sides to 40 pixels. -

Copyright © 2011 W3C® (MIT, ERCIM, Keio), All Rights Reserved. W3C liability, trademark and document use rules apply. Abstract This specification defines Cascading Style Sheets, level 2 revision 1 (CSS 2.1). CSS 2.1 is a style sheet language that allows authors and users to attach style (e.g., fonts and spacing) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS 2.1 simplifies Web authoring and site maintenance. CSS 2.1 builds on CSS2 [CSS2] which builds on CSS1 [CSS1]. It supports media- specific style sheets so that authors may tailor the presentation of their documents to visual browsers, aural devices, printers, braille devices, handheld devices, etc. It also supports content positioning, table layout, features for internationalization and some properties related to user interface. CSS 2.1 corrects a few errors in CSS2 (the most important being a new definition of the height/width of absolutely positioned elements, more influence for HTML's "style" attribute and a new calculation of the 'clip' property), and adds a few highly requested features which have already been widely implemented. -

Web Development Frameworks Ruby on Rails VS Google Web Toolkit
Bachelor thesis Web Development Frameworks Ruby on Rails VS Google Web Toolkit Author: Carlos Gallardo Adrián Extremera Supervisor: Welf Löwe Semester: Spring 2011 Course code: 2DV00E SE-391 82 Kalmar / SE-351 95 Växjö Tel +46 (0)772-28 80 00 [email protected] Lnu.se/dfm Abstract Web programming is getting more and more important every day and as a consequence, many new tools are created in order to help developers design and construct applications quicker, easier and better structured. Apart from different IDEs and Technologies, nowadays Web Frameworks are gaining popularity amongst users since they offer a large range of methods, classes, etc. that allow programmers to create and maintain solid Web systems. This research focuses on two different Web Frameworks: Ruby on Rails and Google Web Toolkit and within this document we will examine some of the most important differences between them during a Web development.

Introduction to CSS
Introduction to CSS Chapter 4: CSS CS 80: Internet Programming Instructor: Mark Edmonds Intro to CSS • CSS = Cascading Style Sheet • What does HTML5 do? – Specifies the content and structure of the webpage • So far, we haven’t controlled the presentation of the webpage at all. • CSS allows us to control the presentation of the page Intro to CSS • Why not control the presentation within the HTML? – You can! – But in general, it’s better to separate! * Why? Because you can swap the style without changing anything in the HTML docu- ment Inline Style • Specify the style in the html tag through a style attribute – E.g. to change the font size, one might apply the attribute style="font-size: 45pt;" which would set the font size to 45pt. Inline Styles • Advantage: – Styling is applied solely to this instance of the tag (useful if we want custom styling for one particular tag) • Disadvantage: – Styling is applied solely to this instance of the tag (meaning it has no generality; we can’t change the style of every tag across the entire document. In our example, we may want to change every <h2> in the document Mark Edmonds 1 Introduction to CSS Example: inline_styles.html 1 <!DOCTYPE html> 2 <html> 3 4 <head> 5 <meta charset="utf-8"> 6 <title>Inline CSS Styling</title> 7 </head> 8 9 <body> 10 <p style="font-size: 45pt">We can apply styling to one HTML tag</p> 11 <p>But take notice it doesn't persist in the document</p> 12 <h2 style="font-family: helvetica, tahoma, sans-serif; font-size: 10 pt; color: blue">We can overrride default settings for tags, notice the bold is still applied! </h2> 13 <p>Note: browser will attempt to use font-family specified in order of the comma-separated list. -
Fiz: a Component Framework for Web Applications
Fiz: A Component Framework for Web Applications John K. Ousterhout Department of Computer Science Stanford University Abstract Fiz is a framework for developing interactive Web applications. Its overall goal is to raise the level of programming for Web applications, first by providing a set of high-level reusable components that simplify the task of creating interactive Web applications, and second by providing a framework that encourages other people to create addi- tional components. Components in Fiz cover both the front-end of Web applications (managing a browser-based user interface) and the back end (managing the application's data). Fiz makes it possible to create components that encapsulate complex behaviors such as Ajax-based updates, hiding many of the Web's complexities from applica- tion developers. Because of its focus on components, Fiz does not use mechanisms such as templates and model- view-controller in the same way as other frameworks. ger and more useful structures.

The Role of Responsive Design in Web Development
Webology, Volume 14, Number 2, December, 2017 Home Table of Contents Titles & Subject Index Authors Index The Role of Responsive Design in Web Development Fernando Almeida Centre for Innovation, Technology and Entrepreneurship, INESC TEC, Porto, Portugal. E-mail: [email protected] José Monteiro Higher Polytechnic Institute of Gaya, ISPGaya, V.N.Gaia, Portugal. E-mail: [email protected] Received October 12, 2017; Accepted December 25, 2017 Abstract Responsive design allows software developers to build a Web page that can dynamically adapt to the size of the devices. This development philosophy enables the rendering of Web pages in a fast and optimized way, ensuring a good user experience on mobile devices, tablet and desktop. In the scope of this study, we intend to explore the main advantages and limitations associated with responsive Web design. We adopted a quantitative approach based on a questionnaire filled by 181 professionals in the industry that allowed us to identify the reasons that lead software developers to the adoption of the responsive design and also address the limitations felt by them. The results obtained indicate that offering a good user experience and increasing accessibility stands out as being the most important advantages. On the other hand, the main limitations include the compatibility with older Web browsers, the higher loading time and the difficulties in optimizing user experience. Finally, it was found that the perception of the advantages and limitations of responsive design is distinct for professionals with more professional experience in the field and for freelancer developers.
