(50%), but the height of the two pictures does not look the same on the screen. This is because using the Box-sizing property changes the area in which one element applies a dimension attribute.
By default, width and height are required to be calculated before they can be applied to the content box of the element. The point here is that if the height attribute of the element is set to 100px, then the true height on the screen is 100px, which is also
ways to make styles:
1) Add a background image to the label;
2): Before;
3) Simple styles can be implemented by adding elements, using CSS.
At the same time with transition, transform and other properties to achieve a simple animation effect.3, switch: Marquee style switching can be achieved by: checked pseudo-elements (ie8+), for IE8 the following browser can be controlled by JS.Demo: pure CSS Implementationa more flattering effect.Animating using SVG: Animated checkboxes

Inner box size calculation (element size)Element space height = content height + (height includes the element content width, border, and inner distance)Element space width = content width + (width contains the element content width, border, and padding)
Currently, most browser elements are based on W3C-standard box models, but some elements in form are also based on traditional box models, such as submit, reset, button, and select elements in

Droid incredible displays the "Wrap_content" and "DP" images at 150x150 px. Since the Droid incredible ' s actual density is 254x254 dpi, greater than the hdpi buckets at + dpi, this means the pixels On it screen is smaller than the bucket size. This causes the 150x150 px image to appear smaller than the baseline size of 0.625 in. The images set with ' in ', ' mm ', and ' pt ' display at 158.8x158.8 px Since more pixels is needed to cover 0.625x0.625 in, a nd the image gets scaled up.Just like
CSS box model is the basis of CSS, but also difficult, this problem often in the interview will be asked, belongs to the classic problem. A lot of the blog is also very vague, so, I am here to reorganize. You can think of each HTML tag as a block, and then this block is wrapped in a few small squares, like a box layer of wrapping, this is the so-called box model. Box model is divided into IE box model and standard box model. IE box model and the standard box modeldifferenceWhat is it? 1. Standar

About Storage TiersEhcache have three storage tiers, summarized here:
Memory Store–heap memory that holds a copy of the hottest subset of data from the Off-heap store. Subject to Java GC.
Off-heap store–limited in size is only by available RAM. Not subject to Java GC. Can store serialized data only. Provides overflow capacity to the memory store.
Disk store–backs up in-memory data and provides overflow capacity to the other tiers. Can store serialized data only.

2 10-Gbps ports can be activated to meet the density requirements of the optical fiber switch above the rack and the edge access switch in the enterprise SAN. The product adopts a non-congested architecture and supports all 32 4-Gbps ports and two 10-Gbps ports running at the same time at the same speed.
