What are the main aspects of lines in layout design?

There are three common forms of layout design. 1. Classical Layout Design This is a layout design form established by some European book design artists represented by Gutenberg in Germany more than 500 years ago. It has the characteristics of elegance, balance and symmetry, and has been used ever since. The characteristics of this design form are: symmetrical left and right with the stop as the axis, uniform size standards for word spacing and row spacing, and a protective frame composed of top, foot, stop and stop in a certain proportion. There are strict corresponding standards for the depth of text ink and the black-and-white relationship of the picture embedded in the center of the plate. Second, grid design Grid design originated in Switzerland in the 1930s. This is a method of layout design using fixed grid: the height and width of the plate center are divided into one column, two columns, three columns or even more columns, thus defining a certain standard size; Use this standard size to control and arrange articles, titles and pictures, so that the layout forms a rhythmic combination, and the unprinted part becomes the background of the printed part. Grid design uses artistic laws such as proportion, force field, center, direction, symmetry, balance, blank space, rhythm, contrast and segmentation to achieve ideal design results. The formation of grid design style is inseparable from the profound influence of architectural art, which uses mathematical proportional relations and has the characteristics of close coherence and rigorous structure. If we only consider the structure of the grid and ignore the flexibility of application, then the grid will become a constraint, resulting in a rigid layout. Therefore, it is particularly important to creatively apply grid design in modern design. Thirdly, the breakthrough of scientific and technological achievements in free-form design and the emergence of laser phototypesetting technology are prerequisites for the birth and development of free-form design. Especially the popularization of computer plate making technology makes free layout design an irresistible trend. The representative figure of freeform design is American designer David Carson. He changed the rules of font and writing, broke through the boundary between people's original understanding of layout design and traditional design, and created an epoch-making new design concept. Of course, free layout design must also have its own formal rules, that is, the version center has no boundaries, the characters and pictures are integrated, the structure is deconstructed, some parts are unreadable, and the fonts are changeable. 1. Version thinking has no boundaries. Free layout design is not only different from strictly symmetrical classical structure, but also different from the division of columns in grid design. But freely arranged according to the contents of characters and graphics in the design object. The space occupied by physical objects is as important as the blank space, and the head, feet, mouth and mouth don't matter, which can give readers rich imagination space. 2. Word-graph integration. This is to regard words as a part of graphics, take this "word graphics" as a painting, and use formal beauty such as rhythm, rhythm, verticality, inclination and realism to achieve the integration of words and graphics; You can also overlap the text to increase the thickness and level of the space. 3. Deconstruction. This refers to dismembering and destroying the classical typesetting order, thus reorganizing the new layout. This is in line with the post-modernism trend of artistic creation and graphic design. 4. I don't study locally. This is the pursuit of higher realm in modern design, and it is the combination of functional beauty and harmony. For example, David Carson often blurs words, which greatly weakens the function of expressing meaning through the rotation and overlapping of words, thus becoming a non-reading part. This is an artistic technique, which simplifies some information especially needed in high-information living environment and strengthens others to achieve a high degree of unity between the two. 5. Variability of fonts. This refers to the full use of various font forms in the design to make the design full of the sense of the times.
