Adjusting the opacity and color of the Container background through gradient overlays

After borrowing some CSS from another website, I find myself struggling as I am not particularly skilled in CSS.

.power-top-container {
    background: rgb(255,255,255);
    background: -moz-linear-gradient(-45deg, rgba(255,255,255,0.9) 49%, rgba(204,204,204,0.95) 98%);
    background: -webkit-gradient(linear, left top, right bottom, color-stop(49%,rgba(255,255,255,0.9)), color-stop(93%,rgba(204,204,204,0.95)));
    background: -webkit-linear-gradient(-45deg, rgba(255,255,255,0.9) 49%,rgba(204,204,204,0.95) 98%);
    background: -o-linear-gradient(-45deg, rgba(255,255,255,0.9) 49%,rgba(204,204,204,0.95) 98%);
    background: -ms-linear-gradient(-45deg, rgba(255,255,255,0.9) 49%,rgba(204,204,204,0.95) 98%);
    background: linear-gradient(135deg, rgba(255,255,255,0.9) 49%,rgba(204,204,204,0.95) 98%);
    padding: .8em 1.5em .8em 1.7em;
    border-radius: 6px;
}

Accompanied by this HTML snippet:

<div class="row">
    <div class="small-10 large-10 large-centered columns">
        <div class="power-container">
            <div class="power-top-container">
                <p class="">Quisque ante quam, imperdiet vitae velius. Donec ligula orci, posuere sed suscipit at, feugiat vel mi.
            </div>
        </div>

    </div>
</div>
<div class="row">
    <div class="small-10 large-5 columns">
        <div class="power-container" style="">
            <div id="" class="power-top-container">
                <p>
                    Quisque ante quam, imperdiet vitae velius. Donec ligula orci, posuere sed suscipit at, feugiat vel mi.
                </p>

            </div>
        </div>
    </div>
    <div class="small-10 large-6 columns">
            <div class="power-container" style="">
                <div id="" class="power-top-container">
                    <p>
                        Quisque ante quam, imperdiet vitae velius. Donec ligula orci, posuere sed suscipit at, feugiat vel mi.
                    </p>
                    <img src="/PowerImages/cat.png" alt="cat Test Image" style="width:180px; height: 180px"/>
                </div>
            </div>
        </div>

I thought it would be clearer with an image demonstration of the gradient effect. https://i.sstatic.net/sQeUB.jpg It's interesting how the transparency increases towards the lower right corner. Although I appreciate the aesthetic, it feels a bit excessive. Despite attempting to adjust various values and percentages, the complexity of the code makes it difficult to prevent the excessive transparency on the right side.

I'm curious to learn more about how these specific values impact the appearance of the content. Any insights are greatly appreciated!

Answer №1

As it approaches the lower right corner, the transparency of the color actually decreases, creating an optical illusion due to its darker shade.

The alpha value in rgba(r,g,b,a) determines the transparency level - the lower the value, the more transparent the color appears.

To reduce the grayness of the color, consider increasing the values for "204".

For example:

background: linear-gradient(135deg, rgba(255,255,255,0.9) 49%,rgba(235,235,235,0.95) 98%);
