  • CSS Introduction

      • What is CSS?



        • CSS stands for Cascading Style Sheets
        • Styles define how to display HTML elements
        • Styles are normally stored in Style Sheets
        • Styles were added to HTML 4.0 to solve a problem
        • External Style Sheets can save you a lot of work
        • External Style Sheets are stored in CSS files
        • Multiple style definitions will cascade into one

      • Cascading Order



        What style will be used when there is more than one style specified for
        an HTML element?




        Generally speaking we can say that all the styles will "cascade" into
        a new "virtual" style sheet by the following rules, where number four
        has the highest priority:



        1. Browser default
        2. External style sheet
        3. Internal style sheet (inside the <head> tag)
        4. Inline style (inside an HTML element)


        So, an inline style (inside an HTML element) has the highest priority, which
        means that it will override a style declared inside the <head> tag, in
        an external style sheet, or in a browser (a default value).

    • 因为GIF格式的图片文件更小，这样能使页面载入的速度更快，当然使用此格式之前必须确定图片并没有使用太多的颜色，当我们使用了GIF格式时，从肉眼上并不能看出图片有什么太大的变化，因此这是可行的。
    • * 接下来的Banner部分还能使用GIF格式吗？
      答案是不能，因为Banner部分是一个细致的图片，如果使用GIF格式颜色会有太大的损失，所以必须使用JPEG格式，将文件导出为banner.jpg。
