I am looking at exporting SVG images using Adobe Illustrator 2020 for putting together my own custom icon library to use in a web page. This is a simple set of 2 artboards.  With a minus icon outline and a minus icon filled.  Exporting When I export these using File-&gt;Export-&gt;Export for Screens... I can select some SVG options.  This then generates the following files: minus.svg &lt;svg id=&quot;Layer_1&quot; data-name=&quot;Layer 1&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; viewBox=&quot;0 0 128 128&quot;&gt;   &lt;defs&gt;     &lt;style&gt;.cls-1{fill:red;}&lt;/style&gt;   &lt;/defs&gt;   &lt;rect id=&quot;minus-filled&quot; class=&quot;cls-1&quot; y=&quot;46&quot; width=&quot;128&quot; height=&quot;32&quot; rx=&quot;4.16&quot;/&gt; &lt;/svg&gt;  minus-outline.svg &lt;svg id=&quot;Layer_1&quot; data-name=&quot;Layer 1&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; viewBox=&quot;0 0 128 128&quot;&gt;   &lt;defs&gt;     &lt;style&gt;.cls-1{fill:none;stroke:red;stroke-miterlimit:10;stroke-width:4px;}&lt;/style&gt;   &lt;/defs&gt;   &lt;rect id=&quot;minus-outline&quot; class=&quot;cls-1&quot; x=&quot;2&quot; y=&quot;48.5&quot; width=&quot;124&quot; height=&quot;31&quot; rx=&quot;4.16&quot;/&gt; &lt;/svg&gt;  When I copy paste the svg directly to a web page and view it, then I see 2 outlined rectangles.  preview.html &lt;!DOCTYPE html&gt; &lt;html lang=&quot;en&quot;&gt;  &lt;head&gt;     &lt;meta charset=&quot;UTF-8&quot;&gt;     &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width, initial-scale=1.0&quot;&gt;     &lt;title&gt;Document&lt;/title&gt;      &lt;style&gt;         svg {             height: 128px;             width: 128px;         }      &lt;/style&gt; &lt;/head&gt;  &lt;body&gt;     &lt;svg id=&quot;Layer_1&quot; data-name=&quot;Layer 1&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; viewBox=&quot;0 0 128 128&quot;&gt;         &lt;defs&gt;             &lt;style&gt;                 .cls-1 {                     fill: red;                 }             &lt;/style&gt;         &lt;/defs&gt;         &lt;rect id=&quot;minus-filled&quot; class=&quot;cls-1&quot; y=&quot;46&quot; width=&quot;128&quot; height=&quot;32&quot; rx=&quot;4.16&quot; /&gt;     &lt;/svg&gt;      &lt;svg id=&quot;Layer_1&quot; data-name=&quot;Layer 1&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; viewBox=&quot;0 0 128 128&quot;&gt;         &lt;defs&gt;             &lt;style&gt;                 .cls-1 {                     fill: none;                     stroke: red;                     stroke-miterlimit: 10;                     stroke-width: 4px;                 }             &lt;/style&gt;         &lt;/defs&gt;         &lt;rect id=&quot;minus-outline&quot; class=&quot;cls-1&quot; x=&quot;2&quot; y=&quot;48.5&quot; width=&quot;124&quot; height=&quot;31&quot; rx=&quot;4.16&quot; /&gt;     &lt;/svg&gt; &lt;/body&gt;  &lt;/html&gt;  This can be corrected by adjusting the internal css (defs/styles), ala cls-1, in one of the svgs so the css classes do not clash. How To... Is it possible to get AI to generate the SVGs so I can get more control over these styles? Ideally I would want to get Adobe Illustrator to output different css classes depending on whether its outline of filled, something like: minus.svg &lt;svg id=&quot;Layer_1&quot; data-name=&quot;Layer 1&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; viewBox=&quot;0 0 128 128&quot;&gt;   &lt;rect id=&quot;minus-filled&quot; class=&quot;icon-filled&quot; y=&quot;46&quot; width=&quot;128&quot; height=&quot;32&quot; rx=&quot;4.16&quot;/&gt; &lt;/svg&gt;  minus-outline.svg &lt;svg id=&quot;Layer_1&quot; data-name=&quot;Layer 1&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; viewBox=&quot;0 0 128 128&quot;&gt;   &lt;rect id=&quot;minus-outline&quot; class=&quot;icon-outline&quot; x=&quot;2&quot; y=&quot;48.5&quot; width=&quot;124&quot; height=&quot;31&quot; rx=&quot;4.16&quot;/&gt; &lt;/svg&gt;  Then control the css colours in my own (global) css using: .icon-filled {   fill: red; }  .icon-outline {   fill: none;   stroke: red; }  Without using the IDs.
Is there a way to edit SVG files in Illustrator where you can specify a CSS class for each path?  I already know in Illustrator that if you give the layer name an actual name, Illustrator will use that name as the path's ID, which is fine if you don't plan on reusing the icon more than once on the same page.  My current workaround is to just use the IDs method, but then later convert the IDs to classes in my code editor, but it's pretty annoying to have to do every time I generate my SVG sprite.  If that's currently not possible in Illustrator, are there any other apps that will allow you to specify that? Or maybe a Grunt or Gulp package?  It looks like you might be able to do it with Inkscape with a , so I might look at that if there's no other good solutions out there.
How do I write a URL in Markdown on Stack Exchange? What are the differences between a pointer variable and a reference variable in C++? Is there a 2D generalization of the coefficient of restitution? The  characterizes a collision in one dimension by relating the initial and final speeds of the particles involved,  $$C_R = -\frac{v_{2f} - v_{1f}}{v_{2i} - v_{1i}}$$   In a 2D collision, the velocity can be split into components parallel and perpendicular to the "plane of collision" (the plane tangent to the two objects' surfaces at their contact point), and the equation above applies to the perpendicular components of the velocities only. One could write  $$\begin{pmatrix}v_{2f\shortparallel} - v_{1f\shortparallel} \\ v_{2f\perp} - v_{1f\perp}\end{pmatrix} = \begin{pmatrix}1 &amp; 0 \\ 0 &amp; -C_R\end{pmatrix}\begin{pmatrix}v_{2i\shortparallel} - v_{1i\shortparallel} \\ v_{2i\perp} - v_{1i\perp}\end{pmatrix}$$   My question is, is it useful (i.e. does it produce a more accurate description of realistic 2D collisions) to generalize that matrix? Perhaps by allowing the top left element to be unequal to 1, or allowing nonzero off-diagonal elements? Or is there some nonlinear relation that works better?

What is the exact reason that normal matter can not exist within an event horizon?  I can understand how a super-dense object like a neutron star could accrete mass until its physical radius is less than its Schwarzschild radius and an event horizon forms around it.   But why can't the neutron star remain inside the event horizon as it was before the event horizon formed? Aside from the escape velocity at the surface reaching $c$, what actually changed?  Why must all matter within an event horizon undergo complete physical collapse to a point? bilinear form - proof I have to prove that the mapping $f(x,y)={\displaystyle \sum_{i=1}^{n}}{\displaystyle \sum_{j=1}^{n}}x_{i}y_{j}{f}(e_{i},e_{j})$  is a bilinear form, that is, inter alia, the condition: $f(x+y,z)=f(x,z)+f(y,z)$  I have: $f(x+y,z)=f\left({\displaystyle \sum_{i=1}^{n}}x_{i}e_{i}+{\displaystyle \sum_{k=1}^{n}}y_{k}e_{k},{\displaystyle \sum_{j=1}^{n}}z_{j}e_{j}\right)=f\left({\displaystyle \sum_{i=1}^{n}}{\displaystyle \sum_{k=1}^{n}}\left(x_{i}e_{i}+y_{k}e_{k}\right),{\displaystyle \sum_{j=1}^{n}}z_{j}e_{j}\right)=\ldots$  and what's next?
