How to Add Scrollability to HTML5 Tables
To add a scrollbar to a table with only a limited number of displayed rows, follow these steps:
1. Define the Table Structure:
Create a basic HTML5 table with the necessary columns and rows. For instance:
<table>
2. Set the Table CSS:
To style the table, use CSS to specify its dimensions, colors, and alignment. For example:
#my_table {
border-radius: 20px;
background-color: transparent;
color: black;
width: 500px;
text-align: center;
}
3. Create a Scrollbar:
To add the scrollbar, focus on the tbody of the table. This section should be configured as follows:
tbody {
overflow: auto;
height: 150px;
}
- overflow: auto enables scrolling when the table content exceeds its height.
- height: 150px sets the visible height of the table to 150 pixels, ensuring that only a few rows are displayed at a time.
4. Maintain Column Alignment:
If your table has a header row, you'll need to ensure that it remains aligned with the main body as you scroll. This can be achieved by wrapping both elements in a tableSection class and applying the following CSS:
table.tableSection {
display: table;
width: 100%;
}
table.tableSection thead, table.tableSection tbody {
float: left;
width: 100%;
}
5. Adjust Column Widths (Optional):
To ensure that all table columns have the same width, regardless of their content, you can include the following CSS:
table.tableSection tr {
width: 100%;
display: table;
text-align: left;
}
table.tableSection th, table.tableSection td {
width: 33%;
}
6. Remove Scrollbars from Header (Optional):
If you don't want the header to be scrollable, add the following CSS rule:
table.tableSection thead {
overflow: hidden;
}
7. Handle Presence of Scrollbar (Optional):
To dynamically adjust your CSS based on the presence of a scrollbar, consider using JavaScript to detect its existence and apply the necessary styles.

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.
