this graph (using APIs such as Jena ). There are two problems with this method: efficiency, and reduced readability of Java code, which is equivalent to the difference in using JDBC instead of hibernate for database operations. In the solo project, I used the first method, which is acceptable in all aspects, but the role of the ontology is not enough. This is a very important aspect, because if there is no difference with traditional projects, what is the reason for the painstaking efforts

CSS3 box learning and css3box Learning The box style provided by CSS3 enables the flexible layout of elements inside the box. We don't need to use float or display: inline to arrange block elements horizontally (box-orient can do this ), you can also calculate the width or percentage of each block to achieve the same balance (box-flex can do it ). So, use sister paper boldly. Set the display: box for the parent element to layout the internal block-le

It is geared toward the resilient layout of some early browsers.First, we'll set the container properties display for a few of the parent elements that need the layout module.We know the block level, which occupies an entire line, similar to the To set the elasticity, take Firefox as an example div {Display:-moz-box;}1.box-
.scale.linear (). Range ([height, 0]);The range of Y and y2 (i.e. like Sugao) should be the same. We put the tick tag on the right side of the y2 so that it looks more symmetrical:Defining axes var Xaxis = D3.svg.axis (). scale (X). Orient ("bottom"). Ticks (5); var yaxis = D3.svg.axis (). scale (Y). Orient ("left"). Ticks (5); var y2axis = D3.svg.axis (). scale (y2).

In the development of ipad and iphone web pages, we may need to determine whether the screen is landscape or landscape. The following describes how to use jQuery to determine whether an iPad, iPhone, or Android screen is a horizontal screen or a vertical screen. In fact, the method is mainly implemented through window. orientation. Let's take a look at the code below. The Code is as follows: Function orient (){If (window. orientation = 90 | win
