Highlighting a Letter with HTML: A Quick Tutorial

In summary, the conversation is about a user wanting to highlight a letter in an equation by changing its color to red, but encountering difficulties with the code. The solution is to include the color change in the LaTeX code itself.

Note: You'll have to quote this to see the code. I don't think the noparse tags are working here.

I recently wanted to correct a member's equation and wanted to highlight a change. I decided to change a letter's color to red:
\(\displaystyle T \left ( \left [ \begin{array}{c}x-2y \\ 3x-y \end{array} \right ] \right ) \)

I'd like to highlight the T: T

But this gives:
\(\displaystyle T \left ( \left [ \begin{array}{c}x-2y \\ 3x-y \end{array} \right ] \right ) \)How do I fix this?

Thanks!

\(\displaystyle {\color{red}{T}}\left(\begin{bmatrix}
x-2y\\ 3x-y
\end{bmatrix}\right)\)

Like so?

YES! Thanks for the tip. For some reason I didn't think of changing the color in LaTeX code. (Doh)

1. What is HTML?

HTML (HyperText Markup Language) is a coding language used to create and design web pages. It is the foundation of all websites and is used to structure and format content on a webpage.

2. How do I highlight a letter with HTML?

To highlight a letter with HTML, you can use the <mark> tag. Simply place the letter you want to highlight between the opening and closing <mark> tags.

3. Can I change the color of the highlighted letter?

Yes, you can change the color of the highlighted letter by adding the "style" attribute to the <mark> tag and specifying the color you want to use. For example, <mark style="color: red">H</mark> will highlight the letter "H" in red.

4. Can I highlight multiple letters or words with HTML?

Yes, you can highlight multiple letters or words by placing them between the opening and closing <mark> tags. You can also use the "style" attribute to change the color of each highlighted letter or word individually.

5. Is highlighting a letter with HTML supported by all browsers?

Yes, highlighting a letter with HTML using the <mark> tag is supported by all modern browsers. However, some older browsers may not support this feature, so it's always best to test your code on different browsers to ensure compatibility.
