Many friends will encounter this situation when using Deamweaver8: the CSS file is linked to the currently edited document and the defined CSS style is applied to the page elements, but no effect is seen in DW8. As shown below.
The main reason is that DW8 has a new "Style Rendering Toolbar", which allows you to easily design for different media types, such as screens, handheld devices, and printouts. Other supported media types are projection devices, TTY (Television Type Devices), and TV media types. It also provides the ability to turn on or off the rendering of all styles by switching the CSS display button on and off.
The method to open the "Style Rendering Toolbar" is: open the "View" menu of DW8, select the lower-level submenu "Style Rendering" of "Toolbar", and then the toolbar panel can be opened in the DW8 environment.
1. Screen 2. Print 3. Handheld device 4. Projection device 5. TTY 6. TV 7. Turn on/off CSS
At this point, click the "Turn on/off CSS" activation button, and the CSS style of the page will be loaded successfully.
