Consider the code snippet below
<div>
@for (int i = 0; i < 10; i++)
{
<span class="@classes[i]">@i</span>
}
</div>
The desired output is (with each character styled differently)
01234567890
However, the actual output shows extra whitespace between each character:
0 1 2 3 4 5 6 7 8 9
An investigation using ILSpy revealed the following render tree structure:
__builder.OpenElement(2, "div");
__builder.AddMarkupContent(3, "\r\n");
for (int i = 0; i < 10; i++)
{
__builder.AddContent(4, " ");
__builder.OpenElement(5, "span");
__builder.AddAttribute(6, "class", classes[i]);
__builder.AddContent(7, i);
__builder.CloseElement();
__builder.AddMarkupContent(8, "\r\n");
}
__builder.CloseElement();
Sequence 4 adds extra whitespaces and sequence 8 adds "\r\n", causing the unwanted spacing between characters.
To solve this issue, one workaround is to write the code in a more condensed manner as shown below:
<div>@for (int i = 0; i < 10; i++)
{<span class="@classes[i]">@i</span>}
</div>
However, this approach can lead to lengthy lines of code and potential formatting errors when auto-formatting the document. To address this, alternative suggestions include:
- Utilizing CSS to ignore whitespaces and line breaks between spans
- Exploring the possibility of adding additional @{} syntax for improved formatting
- Seeking out a parameter or technique to prevent the insertion of unnecessary whitespaces and line breaks in the render tree
