Les framework CSS pour développer des sites plus rapidement Après cette longue absence, je reviens avec une méthodologie que j’intègre peu à peu dans les conceptions web : les frameworks CSS et la notion de Grid. Il existe des frameworks pour développer plus rapidement en Ajax, PHP, Javascript ou en HTML. Mais depuis 6 mois les frameworks CSS ont connu une nouvelle expension. Pourquoi ces outils sont-ils tendances? Peut-être parce qu’ils simplifient la création des pages en proposant une nouvelle façon de travailler. Piqure de rappel Les feuilles de style CSS (Cascading Style Sheets) permettent de travailler sur le design des pages. J’ai découvert il y a quelques mois le système de Grilles (Grid System) qui présente de nombreux avantages : Etat des lieux des framework CSS Les frameworks qui sortent du lot sont : A ce jour, le plus répandu est surement Blueprint car il a une grosse communauté qui pousse le projet en l’utilisant et en créant des modules. Une fois le pas franchi… Dès que vous aurez choisi un système de grid, c’est comme l’adopter.
dataarts/webgl-globe · GitHub Pros and Cons of Using a CSS Framework A CSS framework is a piece of software that has a lot of options for you to use in your HTML development, potentially making it faster and easier for you to develop your website or web app. A CSS framework does this by containing predefined libraries of code. One example is a grid-based framework which sets up a multi-column arrangement with predefined pixel widths so you can focus on creating content instead of lining up blocks of text. But is it good to use a CSS framework? After all, sometimes something that saves you time ends up causing more problems down the line – rendering the saved time useless. There are plenty of CSS frameworks that do different things well, so you can find the specific one that helps you accomplish your web development goal faster. But should you use these CSS frameworks for your web development? Pros of Using a CSS Framework 1. A CSS framework lays out the groundwork for you so you can start developing quicker. 2. 3. 4. Cons of Using a CSS Framework 1. 2. 3.
Abbreviations Syntax Emmet uses syntax similar to CSS selectors for describing elements’ positions inside generated tree and elements’ attributes. Elements You can use elements’ names like div or p to generate HTML tags. Emmet doesn’t have a predefined set of available tag names, you can write any word and transform it into a tag: div → <div></div>, foo → <foo></foo> and so on. Nesting operators Nesting operators are used to position abbreviation elements inside generated tree: whether it should be placed inside or near the context element. Child: > You can use > operator to nest elements inside each other: div>ul>li ...will produce Sibling: + Use + operator to place elements near each other, on the same level: div+p+bq ...will output Climb-up: ^ With > operator you’re descending down the generated tree and positions of all sibling elements will be resolved against the most deepest element: div+div>p>span+em ...will be expanded to div+div>p>span+em^bq ...outputs to div+div>p>span+em^^^bq ...will output to Multiplication: *
KNACSS, un micro framework CSS pour débuter votre projet web facilement Git with Notepad++ | Ankita Kulkarni I am sure all developers love git and notepad++ as a editor. When you are doing web development on windows, its boring to go to the git bash to commit your files. But, there is a convenient way to commit files from notepad++ itself. Here are a few steps to use git and commit your files from Notepad++: Download and install Tortoise GitDownload and install mysysgitDownload the dll file for git on notepad++ from hereDrop the .dll file into the plugins folder of notepad++One thing to make sure, you must already have committed repo in your computerSo next time whenever you commit from notepad++, it can recognize the file structure and all you got to do is to enter username and passwordOpen Notepad++, Plugins -> Git -> Commit FilePut your commit message and rest is simple (username and password) Done :) Like this: Like Loading...
CSS Frameworks + CSS Reset: Design From Scratch Advertisement You don’t have to write the same CSS-code or (X)HTML-Markup over and over again. Whatever project you’re starting to work with, at some point you have to define classes and IDs you’ve already defined in your previous web-projects. To avoid unnecessary mistakes you might want to start not from a blank file, but from an almost “perfect” scratch. And this is where CSS Frameworks and CSS Reset are becoming important. Let’s take a look at the idea behind CSS Frameworks, their advantages and disadvantages, most popular CSS frameworks and dozens of default-stylesheets you can use designing a new web-site from scratch. This article partially covers tools and techniques which use Grids. What is a CSS Framework? A framework is a basic (usually abstract) conceptual structure which you can use as a “scratch” for your web-projects. Advantages of CSS Frameworks You increase your productivity and avoid common mistakes. Disadvantages of CSS Frameworks CSS Frameworks Blueprint Yahoo! Yahoo!
nbviewer.ipython.org/github/masinoa/machine_learning/blob/master/04_Neural_Networks.ipynb Here we will consider how to determine the network model parameters. We will use a maximum likelihood approach. The likelihood function for the network is dependent on the type of problem the network models. Of particular importance is the number and type of values generated at the output layer. Regression Single Gaussian Target Assume that our target variable, t, is Gaussian distributed with an \mathbf{x} dependent mean, \mu(\mathbf{x}) and constant variance \sigma^2 = 1/\beta. p(t|\mathbf{x},\mathbf{w}) = ND(t|y(\mathbf{x},\mathbf{w}), \beta^{-1}) where ND(\mu,\sigma^2) is the normal distribution with mean \mu and variance \sigma^2. p(\mathbf{t}|\mathbf{X},\mathbf{w}, \beta) = \prod_{n=1}^N p(t_n|\mathbf{x}_n, \mathbf{w}, \beta) The total error function is defined as the negative logarithm of the likelihood function given by \frac {\beta}{2} \sum_{n=1}^N \\{y(\mathbf{x}_n,\mathbf{w}) - t_n \\}^2 - \frac{N}{2} \ln(\beta) + \frac{N}{2} \ln (2\pi)
