typeset | TeX line breaking algorithm in JavaScript | Math library

In the following example, how would one utilize flex classes to make columns no.3 and 4 the same height as columns no.1 and 2? Without Javascript, that is.

More specifically, how would I make the height of all columns change automatically to the height of the column with the biggest content?

I am trying to align some fairly long equations the way I would usually do with LaTeX in groff. The general form I am aiming for:

How can I toggle 'Read more'/'Read less' using the following code?

I'm trying to do a customized markdown. I am also using katex with the $ ... $ group. But when replacing expressions, if they are in the $ ... $ group, I have to not replace these expressions.

EXAMPLE : Lorem **Ipsum**(1) is *simply*(2) dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, $ \sqrt{2} **must be no bold **(3) *must be no italic *(4) $ ****(5) **(6)...

• Example (1): Start with ** and end with ** and it's not in a $...$ group so it will be bold.
• Example (2): Start with * and end with * and it's not in a $...$ group so it will be italic.
• Example (3): Start with ** and end with ** but it's in a $...$ group so it will not be bold.
• Example (4): Start with * and end with * but it's in a $...$ group so it will not be italic.
• Example (5): Start with ** and end with ** but it's empty so it will not be bold.
• Example (6): Start with * and end with * but it's empty so it will not be italic.

So, I need two regex. One of them should select those that start with ** and end with ** that cannot be empty and are not in the $ ... $ group. The other is to select the ones that start with * and end with * that cannot be empty and are not in the $ ... $ group.

i am looking for a way to resize all images in an existing markdown file e.g. i want all pictures to have a max width of 80% of the textblock width and have all the images centered and bordered. How do I do this and is there a way to customize borders, e.g. colors and width of that border?

This is an example of my markdown file:

I created three boxes with content in this area. To make the boxes smaller, I've included more functionality. It was working great, but the buttons were not properly aligned. Could someone possibly assist me with aligning those buttons at the bottom of the div?

I work with Carousel view, and i have some dynamicaly elements, which should appear from Json list.

I have multiple paragraph with "id" that is working fine on click but i want to set position of para after click on left menu.

Not sure why I'm getting TypeError: project.Item is not a functionerror when I try to access an object inside of an array returned on my GET request. This is how my code looks. The weird thing about this is that sometimes I get no error with this exact same code.
