How to change background color and the color of the navigation bar?


In the customer CSS file "custstyle.css" (located in webapp subdirectory "customer") a color for the navigation bar (bgcolornavbarNN) and a color for the background (bgcolorbodyNN) can be assigned for each entry (NN...1-9) of the defined server entries in the LOGIN mask..


.bgcolorbodyNN {
    background-color: #rrggbb;

.bgcolornavbarNN {
    background-color: #rrggbb;


The following server entries are defined:

TABEX/4 on Server A
TABEX/4 on Server B

The colors for the first entries (TABEX/4 on Server A) are defined in custstyle.css:

.bgcolorbody1 {
    background-color: #FFCCCC;

.bgcolornavbar1 {
    background-color: #FF0000;

The colors for the second entry (TABEX/4 on Server B) are defined in custstyle.css:

.bgcolorbody2 {
    background-color: #CCFFCC;

.bgcolornavbar2 {
    background-color: #00FF00;

The colors can be defined for up to 99 entries.

CSS notation for colors

There are three different input formats for the colors in the CSS notation:





rr ... HEX value (00-FF) for red

gg ... HEX value (00-FF) for green

bb ... HEX value (00-FF) for blue


rrr ... decimal value (0-255) for red

ggg ... decimal value (0-255) for green
