I have hide title bar in jQuery Dialog
as below
$(\".ui-dialog-titlebar\").hide();
This also hide close button in Dialo
Adding the following CSS will hide the title text and style, leaving the close button in place - see demo.
.ui-dialog-title {
display:none;
}
.ui-dialog-titlebar {
background:transparent;
border:none;
}
.ui-dialog .ui-dialog-titlebar-close {
right:0;
}
However, if you want to change the style of the close button itself (as mentioned in your other question - Arrow in Bottom of jQuery Dialog) then I suggest asking another question since showing the closeText is still a problem when using a jQuery theme - see jQuery UI Dialog - Cannot see the closeText
