Currently, I am in the process of developing a basic website with the assistance of bootstrap and encountered an issue while trying to customize the appearance of an alert box.
In my code structure, I have linked the Bootstrap CSS followed by the Bootstrap optional theme, and lastly my own custom style sheet. The specific alert box that I intend to modify is as follows:
<div id="success" class="alert alert-success">Success</div>
Within my personal style sheet, I have implemented the following modifications:
#success {
color: white;
background-color: black;
border-color: red;
}
The issue arises where although the font color and border color adjust correctly, the background color remains unchanged.
Upon extensive research and experimentation, I uncovered that omitting the optional Bootstrap theme results in the desired background color alteration. Yet, the reason behind this eludes me. Upon reviewing the optional theme's CSS related to the alert box in question, it reveals:
alert-success {
background-image: -webkit-linear-gradient(top, #dff0d8 0%, #c8e5bc 100%);
background-image: -o-linear-gradient(top, #dff0d8 0%, #c8e5bc 100%);
background-image: -webkit-gradient(linear, left top, left bottom, from(#dff0d8), to(#c8e5bc));
background-image: linear-gradient(to bottom, #dff0d8 0%, #c8e5bc 100%);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffdff0d8', endColorstr='#ffc8e5bc', GradientType=0);
background-repeat: repeat-x;
border-color: #b2dba1;
}
It appears that the persistently green color (#dff0d8) is causing the inability to switch to black as intended. My assumption is that the optional CSS theme transforms the background into a webkit gradient rather than a simple solid color like "background-color: black;". Is my interpretation accurate? Moreover, is there a straightforward method to override or disable this gradient for the specified alert box within my customized CSS file?
I'm relatively new to this field and not yet well-versed in the intricacies of webkit rules within CSS. Thank you for your anticipated support.
Update
With the valuable assistance provided by individuals below, I managed to grasp the issue at hand and find a solution. Here it is:
The Bootstrap optional theme employed utilizes a "background-image" property rather than "background-color", contrary to my initial approach. Although I successfully altered the background-color, an additional background-image was superimposed over it. To combat this, two available methods are: - Including "background-image: none;" in the personalized CSS - Or changing "background-color: black;" to "background: black;" within the personalized CSS rule
Thank you, everyone.
