SVG shapes is jagged even with antialiasing turned on - html

I have an svg image of two polygons in 220x220px container but I wonder if I can make the edges antialiased better?
http://jsfiddle.net/swist666/1Lk692xb/
<div class="container">
<svg version="1.1" id="ob" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 595.3 841.9" enable-background="new 0 0 595.3 841.9" xml:space="preserve">
<g id="LOGO">
<polygon points="311,374.7 417.7,401.7 565.4,380.8 438.6,342.4 "/>
<polygon points="298.4,370 426.9,337.5 298.4,298.5 169.9,337.5 "/>
</g>
</svg>
</div>
I have beed playing around with shape-rendering and that was not what I'm looking for.

Why am I unable to apply height and width to my SVG path elements?

Here is my HTML:
* {
box-sizing: border-box;
}
.side-svg {
width: 200px;
height: 200px;
border: 1px red solid;
}
.sto {
height: 100%;
width: 100%;
}
.rect-svg {
width: 200px;
height: 200px;
}
.rectangle {
width: 100%;
height: 100%;
}

I was experiemnting with SVG's and was wondering why my SVG with a rectangle element responded to height and width properites applied to it, but not the path elements in the four inline SVG's above.
I wanted to expand the SVG to be 100% of the viewport, thus setting 100% for both height and width, but this didn't work like it did for the rectange SVG. Why is this?
I set the same viewport attribute for all the inline SVG's as well, so why isn't this working?

As I've commented you need to use viewBox="0 0 32 32" instead of viewBox="0 0 200 200". However I understand you want to have the viewbox to fit exactly the viewport in this case

The size of paths in your SVGs are 32px by 32px, so set set your viewBox="0 0 32 32" and then scale the SVGs by applying width to the svg element, not to the path or rect elements inside of it:
svg {
width: 100%;
}
In order to create a rectangle you shall set the left and top position of the rectangle and set its width and height:
<svg class="rect-svg" viewBox="0 0 32 32">
<rect x="0" y="0" height="32" width="32"></rect>
</svg>

How change path and polyline in SVG?

I have two icons in svg.
Updated:
one
two
First of all, is it possible to make this icons using same markup?
For example:
<g>
<circle ... />
<path ... />
</g>?
Because i can operate only with classes. That mean that i want to change their styles in css and that why i want same markup for both icons.
Also i want remove cx="9" cy="9" from both icons, because this icon is part of the <rect /> and should be placed strictly on the verge of this <rect />. And this cx and cy move it sideways. If i just remove them, then icon become broken a bit. I need to change attributes of path and polyline also. How i can do it? Thank you

As for your re-use of SVG that part already has an answer here:
Inline SVG in CSS
You can do a lot with this using just CSS for example:
.firstxxx,
.secondxxx {
position: relative;
display: block;
top: -1.1em;
left: 6em;
}
.secondxxx circle{fill:blue;}
.containerthing {
height: 4em;
}

I don't know why, but if you want to remove cx="9" cy="9", you can use transform: translate()

You can position the shape where you want and reference the SVG through xlink:href in the shape's attributes definition along with a specific markup through the JointJS Devs plugin. E.g.:
joint.shapes.devs.Model.define('app.MyWindow', {
markup: `<image/><text/>`,
position: {
x: 100,
y: 100
},
size: {
width: 10,
height: 10
},
attrs: {
image: {
width: 8,
height: 8,
'xlink:href': 'assets/my_svg.svg'
},
}
});

I need delete this line on svg

I'm drawing a svg in html, when i draw this i get that line
and i dont want it, how i can sove it, this is my code
html
<svg style="background-color: #fff" version="1.1" xmlns="http://www.w3.org/2000/svg" height="100" width="100%" viewBox="0 0 100 20" preserveAspectRatio="none">
<path fill="#f2f2f2" d="M0 30 V12 Q30 17 55 5 T100 11 V30z" />
</svg>
after the line is another dive, its like a space between svg and another div

That line isn't part of your SVG shape- the height of your shape is 30px but your viewbox is only 20px high - you just need to change viewBox="0 0 100 20" to viewBox="0 0 100 30" so that the whole shape is in your viewport.

I opened it up in illustrator and that line is actually the edge of the artboard. I resized the art board and re-exported the code. I hope this helps. Unfortunately it did cram in some extra info.

As said in the comments on this answer
CSS does not apply cross-document and the img is a separate document.
Images must be self contained in a single file to preserve privacy. –
Robert Longson
So this means you won't be able to include your SVG in your img tag and customize it using CSS on the page. So you have two options:
Inline the SVG code, which means scrapping the img tag. You can then target the SVG as below.
#search-btn svg {
fill: blue;
background: grey;
width: 100px;
}
<div id="search-btn">
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 100 100" style="enable-background:new 0 0 100 100;" xml:space="preserve">

</svg>
</div>
Or you could add styles to the SVG file itself, as below, but this is similar to simply editing the file in Illustrator to get the colours you want.
<div id="search-btn">
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 100 100" style="enable-background:new 0 0 100 100;" xml:space="preserve">

</svg>
</div>

To set the background-color of your <svg> you have to use the background or background-color property. To set the color of the icon you have to use the fill property. See the following example:
svg {
background:yellow;
fill:red;
}
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
viewBox="0 0 100 100" style="enable-background:new 0 0 100 100;" xml:space="preserve">
<path id="XMLID_10_" d="M98.2,89.7L63,54.5c-0.1-0.1-0.1-0.1-0.2-0.2c4-5.6,6.3-12.4,6.3-19.8c0-19-15.4-34.4-34.4-34.4
c-19,0-34.4,15.4-34.4,34.4c0,19,15.4,34.4,34.4,34.4c7.3,0,14-2.3,19.6-6.1c0.1,0.1,0.1,0.2,0.2,0.3l35.2,35.2
c2.4,2.4,6.2,2.4,8.5,0l0,0C100.6,95.9,100.6,92.1,98.2,89.7z M7.3,34.5c0-15.1,12.3-27.4,27.4-27.4c15.1,0,27.4,12.3,27.4,27.4
c0,15.1-12.3,27.4-27.4,27.4C19.6,61.9,7.3,49.6,7.3,34.5z"/>
</svg>

You could use classes for svg elements.
Adobe Illustrator for example offers the possibility to create SVG internal CSS.
But you can also write the style definitions in your own stylesheet.
To set the background use the fill property, like sebastianbrosch mentioned.
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 300 300">
<defs>
<style>
.orange {
fill:#f66d00;
}
</style>
</defs>
<path class="orange" d="M98.2, ... ,34.5z"/>
</svg>

Is there something I can add to make it work in firefox?
