Portfolio Grid black and white hover to colour

Hi, how do I add a code to a portfolio layout page for the grid images to be black and white and for each to appear in colour only when hovered over after 2 seconds or so? I have tried adding codes to the specific pages advanced section but it just appears as text in the header and nothing changes. Please help!

Hi,

You want

Initial: Image in Black color, No text

Hover: Image in Full Color, No text

Is this right?

Hi, yes that's correct.

Can you actually let me know in the instance of this also please! Would like to try both

Initial: Image in Black color, No text

Hover: Image in Full Color, with text

To achieve this, you need to use original is fullcolor, then we will use code to invert its color with this code

a.grid-item img {
    filter: grayscale(1);
    -webkit-filter: grayscale(1);
}
a.grid-item:hover img {
    filter: grayscale(0);
    -webkit-filter: grayscale(0);
}
.portfolio-grid-overlay .grid-item:hover .portfolio-title {
    display: block !important;
}
