How to adjust the background icon and color settings through CSS to solve the problem of the icon being blocked when the mouse is suspended?

CSS style optimization: Solve the problem of mouse hovering to block background icons

In web design, it is a common problem to be blocked by the background color when hovering. This article uses CSS code examples to demonstrate how to adjust background icons and color settings to improve the user experience.

Problem Description: The search box is hovering over the mouse, and the white search icon is blocked by the blue background. The goal is to keep the icon visible while hovering.

Initial CSS code:

 .tx_menu_together .donate-btn-header .lytop_search form .sc_btn input {
    /* ...Other styles... */
    background: #fff url('../img/home/search.png') center center no-repeat;
    background-size: 40px 40px;
    /* ...Other styles... */
}
.tx_menu_together .donate-btn-header .lytop_search:hover form .sc_btn input {
    background: #1a75bc url('../img/home/search-.png') center center no-repeat;
}

Problem analysis: Different images search-.png are used in hover state, causing the icon to be blocked by a blue background (#1a75bc).

Solution: Unify the pictures in hover and normal state, and adjust the color settings to ensure the icon is visible.

Optimized CSS code:

 .tx_menu_together .donate-btn-header .lytop_search form .sc_btn input {
    /* ...Other styles... */
    background: #fff url('../img/home/search.png') center center no-repeat;
    background-size: 40px 40px;
    /* ...Other styles... */
}
.tx_menu_together .donate-btn-header .lytop_search:hover form .sc_btn input {
    background: #1a75bc url('../img/home/search.png') center center no-repeat; /* Use the same image*/
}

Improve user experience by using the same image search.png and keeping the blue background (#1a75bc) ensures that the icon is still visible on the hover state. If the icon is still difficult to recognize against a blue background, consider adjusting the icon color or background color contrast.
