This chapter focuses on the techniques used as background images.
1. Border (add border style, remove border);
2. Set the background image for the page, position setting, fixed background image;
3. Set the background image for any element;
4. The text is placed above the image (as a background image);
5. Add multiple background images to the document (this example uses HTML and body elements to produce multiple background images);
6. Use the transparency effect (using PNG format images) in the page.
Using the web search supplement to learn the padding 4 direction sequence (upper right and left clockwise), flow layout (see the online interpretation combined with the description of the book, probably refers to the page layout elements in a percentage specified location and size).
[Personal Understanding]
Adaptive layout: The container element adjusts the position according to the screen resolution, the text inside the container does not adjust the position (within a certain range), the size of the container element will not change to a certain extent;
Flow layout: The container element adjusts the size of the container according to the screen resolution, the position of each container is proportional, the relative position will not change;
Responsive layout: The container element adjusts the position according to the screen resolution, the size of each container according to different screen resolution according to different proportions distribution;
Static layout: The size and position of the container element is fixed.
