c absolute value

started on the project root path. For example, there is a project named blog, the full path is: D:\work\IDE\workspace \blog. So this path is the JVM's boot path. So the above code if run in eclipse , the output is "D:\work\IDE\workspace\blog."The situation in Tomcat.If you are running a web app in Tomcat, at this point, if we use the following code in a class:File F = new file (".");String Absolutepath = F.getabsolutepath ();System.out.println (Absolutepath);Then the output will be the bin dire

Today, I encountered the position: absolute and relative problems when I was reading CSS. I have been confused and I finally figured it out today. Explanation on css2.0 Handbook:Setting this attribute value to absolute will drag the object out of the normal document stream for absolute positioning, regardless of t

Relative positioning:When the elements are set relative or absolutely positioned, the cascade is automatically generated , and their cascade level is naturally higher than the text flow unless set to a negative value of z-index.And we find that when the relative positioning element is shifted, the surface is out of the text flow, but in fact in the flow of the original relative positioning left the original total width and total height.Absolute positi

, regardless of whether there is a parent box, it is in its own upper left corner as the origin point.Also, it occupies a position, that is, there are other boxes, which will be lined up below.3. Fixed positioningPosition:fixedFixed positioning is also relative to the browser, he is fixed to a browser location. (IE6 does not support fixed positioning, can only be resolved separately)Fixed positioning, also does not occupy position, completely out of standard flow.4. Static positioningPosition:st

elements on the page and can control its hierarchical order by Z-index.) The higher the value of the Z-index, the more it displays on the upper level. ） Absolute positioning: ablution out of the document flow and floating model, exists independently of other objects, and does not occupy a position. 3. The parent container uses relative positioning, and when the child element uses

always adapts automatically with the resolution, while Absolute uses the browser's upper left corner as the original point, the location will not change due to resolution changes. Many people make mistakes in this case. The characteristics of a webpage are similar to those of Relative, but there are some essential differences. Relative: position: relative In CSS. It indicates absolute Relative positioning

is described below.Static default Positioning methodRelative relative positioning, relative to the original position, but the original position is still retainedAbsolute positioning, relative to the nearest non-standard Liu positioning, the original position disappeared, was replaced by the position behindTypically, the value of our element's position property defaults to static or no positioning, and the element appears in the normal flow of the doc

The element positioned as relative is detached from the normal text stream (the meaning of leaving the normal text stream is positioning, there is a reference object, which is positioned with top,bottom,left,right), but its position in the text stream still exists, The layer positioned as absolute is detached from the normal text stream, but the difference from the relative is that its position in the normal stream does not exist.
