This is my first blog, poorly written mess, a lot of understanding. If wrong, please correct me.
1. What is the front-end
That front-end web front section, running at PC side, the mobile terminal and other browsers presented to the user to browse the web. With the Internet technology development, HTML5 , CSS3 application, front-end framework, cross-platform responsive web design to fit screen resolutions, the perfect move-efficient design, giving users a high user experience . Simply put, the front page is displayed in a variety of user front, now also includes some simple applets and applications.
2. how about front-end salary
Internet industry in recent years in terms of salary levels are ahead of other industries, aspects of treatment due to province to province. Basically in the 8k up, look at the technical level and geographic location. So more and more people switch to the front, competitive pressure also will be increasing, the threshold is higher and higher.
3. The front end is simple yet
I personally feel that the front end compared to other languages is relatively simple in terms of a language. Getting Started Front is one of the easiest of all languages of several. Now many universities all computer-related professional web authoring basically opened this course, even many non-computer professional courses have opened so. Teaching content easy to understand. Getting the role is to lead the students to relate to the content taught in html and css section. html5 and css3 rarely involved. (Later there will be related to the interpretation of the term here)
4. a front-end engineers need to know what
(Hereinafter professional interpretation if too many do not understand the direct interpretation of the final turn to face)
Basic HTML and CSS:
1.HTML：
HTML known as
Hyper Text
Markup Language, is a logo of the language. It includes a series of tabs. These tags can be unified document format on a network, and the dispersion of
Internet
resources connected to a logical whole. HTML text is descriptive text consisting of HTML commands, HTML commands can be illustrated text, graphics, animation, sound, tables, links and so on.
Hypertext is a way of organizing information, it is the method by hyperlink in the text of text, graphics and other information associated with the media. These interrelated information media may be in the same text, it could be other documents, or geographically dispersed files on a remote computer. This way of organizing information will be distributed in different locations of information resources to connect with random way for people to find, easy retrieval of information provided.
2.
CSS：
- CSS means Cascading Style Sheets ( C ascading S tylE S heets)
- Styles define how to display HTML elements
- Style is typically stored in a style sheet in
- Adding style to HTML 4.0 in order to solve the problem of the separation of content and presentation
- External style sheet can greatly improve efficiency
- External style sheet is usually stored in a CSS file in
- A plurality of style definitions may be laminated as a
HTML5
and
CSS3
:
HTML and CSS content is added and improved. Including some of the new elements and attributes
JAVAScript：
JavaScript is a scripting language literal, is a dynamically typed, weakly typed, prototype-based language, built-in support types. It is known as JavaScript interpreter engine, as part of the browser, widely used in client-side scripting language, first in
HTML
use on (an application under the Standard Generalized Markup Language) pages, HTML pages used to increase the dynamic function .
AJAX：
Ajax namely "A
Synchronous
J
avascript And
the X-
ML
" (Asynchronous JavaScript and XML), refers to a create interactive
web
pages development technology applications.
Ajax is a technique for creating fast dynamic web pages.
Ajax is a without having to reload the entire web page technical section of the page can be updated.
By exchanging small amounts of data with the server behind the scenes, Ajax can make asynchronous page updates. This means that, for certain parts of the page to be updated without reloading the entire page.
Traditional web page (do not use Ajax) If you need to update the content, you must reload the entire web page.
JSON：
The JSON
(
the JavaScript
Object Notation, the JS objects notation) is a lightweight data-interchange format. It is based on
ECMAScript
subset (European Computer Society norms established by js), using completely independent of the programming language of the text format to store and represent data. Simple and clear hierarchy make JSON an ideal data-interchange language. Easy to read and write, but also easy for machines to parse and generate, and effectively improve the efficiency of network transmission.
jQuery：
jQuery is a fast and concise JavaScript frameworks, following yet another excellent Prototype JavaScript code libraries (
or JavaScript framework
). jQuery design aim is to "write Less, Do More", that is advocated write less code, do more things. It encapsulates the JavaScript code for commonly used functions, provide a simple JavaScript design patterns to optimize HTML document manipulation, event handling, animating and Ajax interactions design.
Popular point that, if the constitution is seen as a site of a house, then HTML (including HTML5) is equivalent to the basic structure of the house, and CSS (including CSS3) is a simple decoration of the house and decorated, they are static of. JavaScript is undergoing renovations to the house from the inside to the outside, including some linkage and the house owner. These three constitute a barely habitable house
Above is basically a front-end engineers need to master the most basic things, the latter also need to know there are a lot of things, there is not a one-time lists all the. After all, each in front-end technology development and new.
This is my first blog, poorly written mess, a lot of understanding. If wrong, please correct me.
If you are reading this blog technology Daniel, hoping to leave valuable advice and experience, if the technology is not white or students are preparing to enter into the row or rows, if this article help you, that's my with pleasure.
