Adding a Checkbox to a Select Option Menu
While it's not possible to directly embed a checkbox within a select element, you can achieve a similar functionality using a combination of HTML, CSS, and JavaScript.
HTML Code:
Create a div container with a class of "multiselect" that will hold the select menu and the checkboxes.
Within the "multiselect" div, create two child divs:
- selectBox: This div will contain the select element and a transparent overlay that covers the select option when clicked.
- checkboxes: This div will hold the individual checkboxes and will initially be hidden.
CSS Code:
Apply the following styles to the elements:
- multiselect: Set a fixed width to constrain the size of the menu.
- selectBox: Position the select element and the overlay relative to the div.
- overSelect: Use absolute positioning to cover the select option.
- checkboxes: Hide the checkboxes initially using "display: none". Style the labels to resemble select options.
JavaScript Code:
Add an event listener to the "selectBox" div that toggles the visibility of the "checkboxes" div when clicked.
Example Code:
<form> <div>
This code will provide a Select Option menu with checkboxes that can be toggled on and off when the select option is clicked. The checkboxes will mimic the behavior of select options by displaying the selected items in the menu.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
