The subject of the research in this scientific paper is a description of the opportunity for navigation through the websites, with special emphasis on analyzing different types of navigation systems. The important part of my paper is analyzing the characteristics of various navigation structures on the web pages, as well as the analyzing technical methods of displaying navigation on various users' computers. In addition, users can have different browsers, different operating systems, and different preferences in terms of their computers' settings. All these technical issues will have an impact on how the web pages will look on the user's computer. Another thing described in my work is the interpretation of navigation structures on the user's computer monitor. A special overview is made for the correlation between web navigation and all the other graphic elements in the web pages from point of view of a visual harmony of the websites. Additionally, here I give overall directions for using navigation type and their characteristics when designing websites, same as the description of some opinions and advice on the same topic. After that, I analyze twelve problems which arise from displaying navigation on the websites on the user's computer. In this paper, I will come across a few solutions for all of them, as well as recommendations for when to choose which solution. 

The subject of the research in this scientific paper are images on the websites, with special emphasis on displaying images chosen by the Web designer, along with its characteristic, on computers of various users. In addition, users can have different operating systems, different browsers, and different preferences in terms of their computers settings. An overall direction for using images and their characteristics when designing web pages, as well as some advice and opinions on the same topic are presented here. After that, several problems which arise from displaying images on the web pages of the computer of users are analyzed, for which a few solutions for the problems, as well as recommendations on which solution when to be chosen are also given in this text. A problem with a speed for loading web pages in correlation with size of images on those pages is studied as well. Then, problems with a speed for loading web pages in correlation with number of images on the page, problems with loading speed of second image on rollover, problems with a speed for loading web pages in correlation with size of background image, problems with texture in vertical bars used for background in web pages, and problems with users monitor size and background image are also analyzed. Finally, the problem with displaying the page without specifying image height and width is also considered.

The subject of the research in this scientific paper is the text on the Web pages, with special emphasis on the interpretation of the text fonts chosen by the Web designer, along with its typographic features, on computers of various users. In addition, users can have different operating systems, different browsers, and different preferences in terms of their computers settings. An overall direction of the choice of fonts and their characteristics when designing Web pages, as well as some advice and opinions on the same topic are presented here. After that, several problems which arise from the interpretation of the text on the Web pages of the users are analyzed, for which a few solutions for the problems, as well as recommendations on which solution when to be chosen are also given in this text. The problem of having no fonts, chosen by the designer, on the user's computer is studied as well. Then, the possibility of the users to change the default font, given by the designer, on their computers, and the possibility to change the typographic features of the default font is also analyzed. Finally, the problem with incompatibility with different operating systems and Web browsers in visualizing the fonts is also considered.
