CSS。 菜单文字颜色在悬停时未更改或菜单文字颜色已更改

Question

I have created a sub menu for a website using CSS. But I want to change menu text color on mouse hover. But when I change the code to 'make it work' the other text color in the sub menu changes.

Problem 1 CSS code

ul ul {
    display: none;
}

ul li:hover > ul {
        display: block;
}
ul#header_menu {
    list-style: none;
    position: relative;
    display: inline-table;
    border-bottom: 1px solid #ccc;
    width: 100%;
}
ul:after {
        content: ""; clear: both; display: block;
}
ul li {
    float: left;
    padding-right: 10px;
}
ul li:hover a {  

    color: #1583BE;

    transition: color .16s linear;
}
ul li:hover {
    color: #1583BE;
    transition: color .16s linear;
}

ul li a {
    display: block;
    color: black; 
    text-decoration: none;
    font-size: 1.3em;
}
ul ul {
    background: white; 
    padding: 0;
    position: absolute; 
    top: 100%; 
    width: 100px;
    border: 1px solid #ccc;
}
ul ul li {
    border-bottom: 1px solid #ccc;
    float: none; 
    position: relative;
    list-style-type: none;
}
ul ul li a {
    font-size: 1.2em;
}
ul ul li a:hover {
    color: #1583BE;
    transition: color .16s linear;
}

Problem 2 CSS code

ul ul {
    display: none;
}

ul li:hover > ul {
        display: block;
}
ul#header_menu {
    list-style: none;
    position: relative;
    display: inline-table;
    border-bottom: 1px solid #ccc;
    width: 100%;
}
ul:after {
        content: ""; clear: both; display: block;
}
ul li {
    float: left;
    padding-right: 10px;
}
ul li:hover a {  

    color: #1583BE;
    transition: color .16s linear;
}
ul li:hover {
    color: #1583BE;
    transition: color .16s linear;
}

ul li a {
    display: block;
    color: black; 
    text-decoration: none;
    font-size: 1.3em;
}
ul ul {
    background: white; 
    padding: 0;
    position: absolute; 
    top: 100%; 
    width: 100px;
    border: 1px solid #ccc;
}
ul ul li {
    border-bottom: 1px solid #ccc;
    float: none;
    position: relative;
    list-style-type: none;
}
ul ul li a {
    font-size: 1.2em;
}
ul ul li a:hover {
    color: #1583BE;
    transition: color .16s linear;
}

I have tried to make it work but not successfully. Sorry for my, sometimes, poor English. Thank you for your time.

Answer 1

I worked from your first fiddle. The problem is where you apply the :hover on. So if you change there this part (line 22 of the CSS)

ul li:hover a {  

    color: #1583BE;
    transition: color .16s linear;
}

to this

ul li a:hover {  

    color: #1583BE;
    transition: color .16s linear;
}

If I understood your question correctly, then that solves your problem.
