Tis is my jquery
$(document).ready(function()
{
$("ol > li").css({margin: "1em", fontWeight: "bold"});
$("ol li li").css({fontWeight: "normal"});
$("li").hover(function()
{
$(this).css('border-color', 'red'); //switches color when on
},
function()
{
$(this).css('border-color', 'white') //switches back when the mouse moves off
})
});
What you have looks correct, unless you haven't assigned a border width and style yet. In that case, there's nothing to show the color.
You could do this for example:
$("li").hover(function()
{
$(this).css('border', '1px solid red');
},
function()
{
$(this).css('border', '1px solid white')
});
Or set the initial border before you do the hover:
$("ol > li").css({borderWidth:"1px", borderStyle:"solid", margin: "1em", fontWeight: "bold"});
$("ol li li").css({fontWeight: "normal"});
$("li").hover(function()
{
$(this).css('border-color', 'red');
},
function()
{
$(this).css('border-color', 'white')
})
