Hi all - I have a little experience and have written an E-book in HTML and turned it into an Epub with Calibre. However I got an enormous amount of errors in running it through Epubchecker which were all to do with my images which are in SVG format.
I then saw a post here about the Sigil validator and got it to open my HTML file and ran the validator. The only problem I am getting is also with my images but not the same as through calibre which all seemed to have to do with the xml coding going on under the bonnet of SVG images.
The problem I encountered with Sigil's validation was that I show the width of my images (mostly svg but dome gif and jpegs) as: width="100%" and height="auto". But the validators describes the height expression as: facet value 'auto' does not match regular expression facet '[-+]?(\d+|\d+(\.\d+)?%)'
I changed width to 100% but of course that stretched the picture. I did a wee biy of checking and it seems that expression must be in % or pixels but there are several hundred images and they are all different sizes and I don't really fancy going through them individually and enter the sizes. So I wondered if there was an easy way
Oh I should add that the actual "width" and "height" sizes don't actually affect the appearance of the images on screen as they are all wrapped in div tags for altering alignment and width and of course the width represents a percentage of the screen width and not the image width so I also am thinking that perhaps the width and height aren't strictly necessary.
Sorry this is so long but I wanted to try and cover all the bases - I hope someone can help and give thanks in advance.
